HDMI Distribution over your Home Network? Low-Cost HDMI Matrix using IP-Based Hardware

[@apalrdsadventures]

I made an update video answering YOUR QUESTIONS! kzbin.info/www/bejne/a5-QmYRobtaKnpY

[@billkillernic]

could you please test sending an HDMI signal to a transmitter and then directly hook the transmitter to a PC via its ethernet port? I would to use OBS to stream my game session from my gaming pc via ethernet to the PC that is going to compress the signal and upload the session (so that I dont lose FPS performance on my gaming pc) and I would like to do that over ethrnet so that I wont need to buy an expensive capture card. So topology would be gaming PC having 2 HDMI cables, HDMI1 hooked to my main gaming monitor, HDMI 2 hooked to that transmitter you showcase here and then ethernet from that transmitter hooked on the ethernet port of my second pc and then receive that signal over OBS.

5-6Mbps sounds very low though. Even if it using H.264 there should be some easily noticeable visual degradation at 1080p60 with full motion video. Especially if it transmits RGB/4:4:4. Otherwise it's a very neat device.

[@PierreVilleneuve88]

Yeah I was thinking the same. Taking 12+Gb data from HDMI and converting it to 3Mb stream is hugely compressing it. more than 1000:1 in fact.

[@foobar5442]

[@TheInsomniaddict]

I doubt it's the raw video, and more likely JPEG or MPEG conversion to "update" the display. This would be similar to what thinclients or zero clients would do. That's amount of bandwidth usage would be about right.

[@Chris_Cable]

Multicast triggered a bad memory.. A long time ago at a company i used to work at.. we just bought Norton Ghost to image a bunch of machines. We found out the hard way that our infrastructure didn't like multicast. I've never seen the network guys run to fast in my life.

Networking has come a long way! Now you can migrate everything to IPv6!

[@Darkk6969]

@@apalrdsadventures IPv6 is fun. Works well with pfsense and several of my MikroTik switches. 😁 There is one thing I've discovered with pfsense's HA Proxy is if you have IPv6 on the WAN you don't need IPv6 on the backend server as pfsense will NAT6to4 it. At first I thought I needed that but it works fine without it since I don't have static IPv6 from Comcast to setup internal DHCP6.

[@apalrdsadventures]

HAProxy is a bit of a different beast, it's not really doing NAT, it's terminating the TCP socket and then opening a new one to the backend server and passing the data through (possibly doing TLS termination too). I actually have Comcast too, and I've found that DHCPv6 PD is effectively static. They haven't changed my prefix in over a year, so I treat it as static and use internal DHCPv6, but I also use a ULA prefix at the same time for internal communications.

[@frequentfrenzied]

I used little HDMI to IP converter boxes like the ones featured in this video to drive several displays from a single media computer at a church about 8 years ago. They had several TVs spread around their building that they wanted to display their announcements and various other things on and already had ethernet to most of the rooms where these TVs were located so we thought that this would be a good solution for them. What we found out was that the converter boxes that we used got extremely hot while they were in use and ended up cooking themselves to death after a couple of months. We ended up coming back in and putting a low powered computer at each screen instead that could be managed via a VNC connection if anything needed to be updated. I haven't given these converters another thought after that job as we had a 100% failure rate on them in less than a year. I don't know if anything has changed since then but I feel like that is definitely something everyone should be aware of before buying into this solution.

[@Mtaalas]

Many manufacturers, especially ones selling cheaper devices, have horrible over heating issues. I work at a AV-systems integrator as a service technician and I've blasted my fair share of manufacturers, even big ones, about their really really bad thermal designs and inefficient electronics design. Before working at this company, I did a lot of electronics design so I have keen understanding of how electronics works and how to design stuff regarding thermals and for long service life... and it's expensive and takes along time and also usually makes the device much, much bigger. And many companies don't create their equipment for high duty cycles. Many expect that their devices are on for 1-2 hours a day and have ample free air to cool or are installed in a rack that's forcefully cooled... then people people and use them in unptimal conditions 24/7 stuck into another piece of equipment that heats uo the ambient... and that's that. One has to pay ridiculous amounts for equipment that can serve 24/7/365 for 5 years... and that makes the pool of equipment to choose from very small as well..

[@Netz0]

I was wondering about this. Like any computing device, they have to do the encoding and decoding on each end, not only heat but reliability is probably a big issue. How long until they fry or, worse, if they hang every couple of hours, and you need to reset the power manually on each one. I suspect these are fine for casual KVM use, but 24x365 hours a day running video, I guess they will not last long before they die. And if you have to get more expensive ones in terms of quality, at that point it is just more cost affordable to put budget thin clients on each endpoint that can do more things as well. They might involve more time in terms of management, but also more reliable in terms of electronics. Thanks for sharing!

[@Netz0]

@@Mtaalas Agree, but on their marketing page they list usage cases like security cameras monitoring, which means they are advertising them for 24 - hours use. As you said, based on experience, it is very unlikely they are actually rated for that sort of use, or they even tested them for longevity.

[@jasonbrindamour903]

Same here. I noticed they got very hot and started dying, we use them for security camera monitors. This week I am replacing them once again because they just don't work for long. I had even made fan driven cooling boxes for them to no avail. I'm thinking now I want to just hack some of the HDMI optical cables with my own length optics and go that route.

[@TheInsomniaddict]

I've not used HDMI to IP converter boxes, but if you only need a couple displays we've had good luck with cheap HDMI extenders attached to an HDMI splitter box. You do need to be careful in cases where you're attaching to TVs with different resolutions as the splitter can only use a single resolution, or have a device that's smart enough to run 2 separate streams for eg 720i and 1080p, and then use a separate splitter for each stream. The cheapest extenders don't carry the EDID information from the splitter/PC and so they don't allow you to set the resolution. They still work fine, but you need to make certain they are uniform (all 720i, or 720p, or 1080i, or 1080p with no mixing) and attach to TVs that support the hard-coded resolution. You can't run these extenders over switches; they have to be connected one-to-one: Tx-to-Rx. At the price point, even getting a few failures once in a while is fine. We've had problems with more expensive options that used DIP switches on the transmitter/receiver pair as they became extremely picky over time and failed. Current ones that just pass through EDID or are hardcoded for a single resolution haven't failed (yet), but they're cheap enough that keeping a couple spare pairs and replacing as needed isn't a problem. Still, they've lasted for upwards of 5 years in certain cases and are on 24/7. Considering how cheap the units are, I don't believe they do any conversion of the video stream and instead just send it as is with some limitations on refresh rate and colour depth to stay within the 1gig bandwidth. They get a bit warm but not hot, and i've yet to notice wire issues for the ones that use passive receivers. If you only need a single stream these extenders might be the more reliable option. A single Rx or Tx unit for the shown TESmart unit is about $50, or $90 for both. The dumb extenders are about $20-30 for a Tx/Rx pair, and as long as you stick to a singular model they're interchangeable. Add a splitter for about $100 ( assuming 1 in, 8 out) and you're good. You pay a bit more in space/money for HDMI cables to hook everything together, but there's less to fail since there's no active conversion. Food for thought, I'll be picking up a couple of these IP units for testing myself. I like the idea that I can hook up multiple racks/benches, and then have them be accessible from multiple workstations around the office. The fact that they don't pass through USB outside mouse/keyboard would actually be a plus in my use-case. One of my racks has a KVM that can change selection via IR, which this might work with. Pretty sweet.

[@siberx4]

This is a really cool device! It's super unfortunate it doesn't use general-purpose USB forwarding protocols (like what VirtualHere does, which works beautifully), because it really limits the potential use-cases if you want to do things like have a headset with bidirectional audio or use a gamepad at the remote end.

[@tetyoonlee4373]

Yeah and given that volume control buttons don't work I strongly suspect it means even other HID devices like controllers and joysticks don't work at all or are risky. And depending on the distance and walls etc, I don't think you can assume even wireless devices will work if just plugged into the host machine

[@obuw1]

Exactly what I thought. It really sucks that the USB is not general purpose. Probably means that it doesn't work with wireless usb keyboards & mice either. Has a ton of potential if they can release a new version with full USB support though. Edit: Nevermind, he's using a wireless mouse. So I guess they work at least. That kind of widens the use cases for sure.

Thanks for the video. However it would be great if you would measure "the interesting" parts of the product. The lag, the compression artifacts, etc... Because if you are compressing 1080p60 which is almost 3Gb/s into a single digit Mb/s, then the compression must be pretty impactful. And this product is marketed more as IPKVM than a HDMI over IP. You do not need any fancy measurement tools to do it. For example you can set the input monitor and the output monitor side by side, write simple program to flash black and white and then record it on your phone with 60FPS. Then you can watch the video frame by frame and see what the delay is. Similar setup can be used to check for the compression artifacts. Switch different images fast, try one pixel wide black and white lines, 1 pixel checker board. Even the "standard" HDTV test patterns include patterns for checking some of these things. Or run a more demanding video or game/demo.

[@testthisfordecficiencies]

On these crappy units, sure. If you go high-end its lossless with ms response times. Look at Crestron DM-NVX for example. 10 times the price though.

[@radekhladik7895]

@@testthisfordecficiencies I have some experience with HDMI over IP. And one thing is for sure. 3Gbit/s > 1GBit/s 🙂 So unless you are using 10Gbit Ethernet you need to have some form of compression. And I've seen a fair share of weird compression artifacts...

[@testthisfordecficiencies]

@@radekhladik7895 Definitely compressed. But a good algorithm and enough processing, the picture can be uncompressed pixel perfect at the other end. 4K60 4:4:4 12 bit @ 18 GBPS over a 1Gbps ethernet. Crestron, QSC, Extron all do it at only a couple ms of latency. I have professional experience with AVoIP and broadcast. Evertz does it really well to.

[@uncrunch398]

There is hardware that can stream av1 at ridiculously low bitrates before it appears annoying. Most low action 4k would be transparent well below 1Mbps. I wonder if anyone can figure how to leverage that in a desktop streaming solution that gives the same experience as hdmi over ip. I don't know how many times to multiply the bitrate by to look the same at the lowest possible latency though. It's a clear tradeoff and probably would be noticeable; without caring about latency would be annoying where input lag is important.

[@powerpower-rg7bk]

For general home usage, these are fine, nothing special. However, these are likely high latency in terms of encoding so I wouldn't recomment them for gaming as they are likely using H.264 for encoding/decoding. Curious if you can just pop open a VLC instance on a computer and watch the raw stream. Opening something like Bonjour browser on the network could point you toward the proper stream url. As for other other devices, I can name a dozen of them off hand. (Crestron NVX using M-JPEG2000 or M-JPEG-XS, Samsung/Harman/AMX/SVSI using M-JPEG2000 or H.264, SDVoE consortium, Dante AV using M-JPEG200, Biamp TesiraLux using M-JPEG over AVB/TSN capable networks, Extron NAV using their own hybrid codec, Atlona Omnistream using Dirac/VC-1 or Dirac Pro/VC-2, NewTek using NDI, SMPTE 2022 using MPEG2, SMPTE 2011 using uncompressed SDI encapsulated over IP for broadcast work, various H.264, various H.265/HEVC, and various AV-1 systems coming soon). The problem with so many is that while various vendors can use the same core codec, the discovery, encryption and handshaking protocols are all different between vendors. The reasoning being mainly vendor locking as many of these systems end up being the same price as HDbaseT equipment in terms of end points but they end up being 'cheaper' due to the presence of an existing networking switch at the business/enterprise/corporate level. Oh yeah, I forgot that HDbaseT-IP was also a thing for a little while as that was supposed to be the HDbaseT consortium's bridge to the IP world. This is why that while I strongly believe that AV-over-IP is the wave of the future, I tend to avoid it today until this period of proprietary vendor-lock in is over. For 1080p60, 1 Gbit Ethernet is fine with most of the various solutions I listed above. Things get challenging when attempting to do 4k60 over the same 1 Gbit Ethernet link. So far I've been able to tell that compression is invoked using all the capable codecs at 1 Gbit. Those that offer 10 Gbit support fair far better at 4k60. What I want to see are various 2.5 Gbit capable equipment as that can use the same cabling as 1 Gbit Ethernet because well they're nearly the same thing. For the consumer space, good quality, low latency 4k60 support is out of reach outside of the high end still. (Arguably at high latency, low quality, various solutions already exist today.) Those willing to look at used pro/enterprise gear for the consumer market is another story but buyer beware as with all used goods. One other aspect that differentiates between consumer and pro/enterprise gear is PoE support. This means less outlets to have around devices which is generally a good thing. Pro/Enterprise systems also have management features that are nice for admins but generally lost on consumers. Security is a big thing for business and all products aimed at them adhere to HDCP and encrypt their network traffic. Consumer systems are more wild west here. As for USB extension over IP, full encapsulated USB 2.0 support exists. A company called Icron makes the chipset to do it and resells them to various vendors. This is why most USB extenders over Ethernet look the same as they literally are minus the logo on them.

For cheaper non-routable point-to-point 4K HDMI over UTP, we use CleanDigital TPU4120 kits, but they only do 4:2:0 - good enough for workplace presentation requirements, but what's great is that they are rock solid - they never ever fail, and one end conveniently powers the other end via PoE so it's just one PSU with a range of 100m - the supplied mains power PSU can be connected to either the TX or RX side. They also have serial connections to relay commands for those devices with RS232 connections.

[@forresthopkinsa]

I'm currently using NDI for video-over-IP in a large live production setup. It works flawlessly over the existing network, and since it's software-based, we don't need additional hardware on the transmitter side - the machine is already connected to the network anyway, so it just sends it. On the receiving sides we use a mix of thin clients (raspberry pis) and hardware solutions (e.g. the $150 Birddog Play, which is super convenient) I was initially drawn to NDI because it's both low-latency and high-fidelity. The one cost is bandwidth - but for a hardwired gigabit network, you can afford a much higher bitrate than would ever make sense over the internet. Another lovely aspect of NDI is that there's a good amount of existing management software to handle its network connections, so you get pretty good visibility.

[@graysonpeddie]

Maybe one day there will be HDMI 2.1 boxes that work over IP. I'm talking 4k at 120Hz with VRR support. That would be cool to have. USB 2 would be nice to have.

Have you measured the latency (both single path and roundtrip)? I'm interested in how many ms it is. Another use case that might be interesting to test is to have the streams recorded with ffmpeg or even vlc (if it's a generic h264 encoded format that is standardized, otherwise you might have to capture the raw packets and transcode it to a known standard in order to play them back). It would also be nice to get it working over a layer-2 VPN and see how it performs. Nice video and keep up the good work!

[@apalrdsadventures]

I don't have a way to measure HDMI latency without also introducing latency of the capture setup (which is not great with what I have). So at best I can try to get the number of frames behind at 60fps. I suspect it's either 1 or 2. But I can definitely do VPN testing in the future

[@jonathandebolster8089]

@@apalrdsadventures an easy way to test the latency from transmitter to receiver is to passively split the hdmi on the input, connect it to a monitor directly and then put a second monitor next to it that is connected to the receiver (ideally it should be two monitors of the exact same type, but it won’t make that much of a difference). Then display a clock on the pc that also displays milliseconds (just an online timer will work fine). Take a photo with your phone or camera from both the screens at the same time, and the difference between the two clocks will be the latency with an accuracy depending on the frame rate.

Excellent video, a few questions in case you do a follow-up: 1) will the transmitters constantly blast data at the router even if there are no receivers tuned to their channel? 2) what kind of power consumption are the transmitters/receivers using (especially when there are no receivers are tuned, are the constantly compressing the video)? 3) if you have a WiFi hotspot set up, it would be critical to ensure multicast is correctly handled in your network not to blast this into the air? how could one verify that's the case?

[@apalrdsadventures]

1. Yes, but the switch should ignore it if it supports IGMP snooping (no subscribers to IGMP group = nobody to forward the traffic to). If the switch doesn't support IGMP snooping, it will treat multicast as broadcast and send it to everyone, which is.... not ideal. 2. Transmitter doesn't turn off when there are no receivers. Transmitter pulls about 1.5W (Kill-a-watt isn't very accurate down this low though). 3. It depends. AFAIK a WiFI AP should always be doing IGMP snooping and only sending multicast packets to clients subscribed to the group, but I'm sure there's some AP out there that does this poorly. It would show up as a constant data rate when there are clients connected to the AP but otherwise not doing anything.

Finding a transmitter like this that allows me to adjust the frame rate and bittrate has been a challenge for me. I HAVE found "ONVIF encoders" that does encode HDMI over IP and under other formats such as ONVIF and with a matching decoder I could very well stream my DVR's HDMI output at pretty much any framerate and bitrate I want, but the problem is that for those encoders, you can't attach a mouse to them to also be able to control the device in its entirely, its just HDMI transmission and that's it.

Actually this is great for bussineses with lots of mirrored screens, since a single hdmi source is going over ip, the switch will duplicate that single input into different outputs withoud increasing the load of the source hdmi because of it, well, running a lot of duplicates

My experience with TESmart's USB keyboard/mouse KVM firmware is that it's rather atrocious. Eating media keys, dropping out keystrokes, breaking extended functionality (like battery status on Logitech mice) and plain old crashing and requiring switch power cycle.

Can 2 or more TESmart HKE12MMA20 devices be connected to the Mikrotik router and can be streamed via VLC on a PC? like IPTV players?

Currently no ability to stream to VLC, although it's just streaming bare h.265 with no encapsulation (this seems to trip up VLC). We (my discord community) were able to decode it, but not with VLC.

The bank I was working for did something like this in 2009. They pulled in a fiber line then to our network stack. From there they had cat 6 running out. A few of those lines went to the display TVs we had. There would be an HDMI cable out from the TV to a box about the same size here that had both Ethernet and HDMI connections. We get news and promotions played on it during the day. It was a solid solution for us.

I connected two Lorex DVR security camera systems across 300 ft in our office at work. Using two JustAddPower transmitters (one TX for each DVR box with 4 cameras each) Out to 3 offices, each with 2 receivers (1 for each DVR) Also used 2 DLink unmanaged switches to distribute the 3 feeds per DVR to the 6 monitors.

[@gavinnoname1424]

These could also be switched using VLANs rather than having to use their remote to set a number. Example VLAN1 has Transmitter1 connected VLAN2 has Transmitter2 connected. Then you can control which source your receiver gets by changing the VLAN assignment of your receivers switch port. Note. You'd need to leave all devices set to the same 1-16 number.

[@gavinnoname1424]

Assuming your switch has API/SSH/Serial interface the switching could be controlled by HomeAssistant, Alexa, etc

[@apalrdsadventures]

Of course, and that's the approach I'm using in the next episode with the Mikrotik hEX. But it's not as approachable in general, which is why I started without it.

[@gavinnoname1424]

@apalrd's adventures it should also make to product scale greater than 16 transmitters. Because they can all be set to channel 01 and not clash because of the VLAN isolation. This is how the JustAddPower devices work. There is no addressing for them. The homeautomation systems like Control4 have drivers to talk to switches and reassign VLANs

The problem with that solution is the small number of USB ports available. You can put a HUB, but that will slow things down.

I am giving a dislike because you were not honest with gaming experience. It has a huge input delay. I could see that you move your mouse and the display response was almost half a second later. That is no way to play any game. It may be a good sytem for many other things but not gaming.

[@Kemia_]

[@KauaiboyRayce]

Nvidia Shield Pro costs about the same and has quite a bit more functionality. I fought it for awhile myself.. even pondering various NDI solutions since they hinted at the lowest latency. The shield is just the best.

[@mechanicalmonk2020]

You don't even need that for something like this. A $10 Android TV stick will do the job. The only issue is ensuring the connection always stays up.

[@forresthopkinsa]

NDI is pretty fantastic, but you can get similar performance from Moonlight as well if you spend some time tuning it.

[@moeburn]

I just ran 30ft of HDMI through the walls, works for me at 1080p120 w/HDR. What I'd like to figure out is USB, because right now the only way this works is with wireless mouse, keyboard, gamepad and headphones. I'd like to be able to use my USB joystick, but USB is limited to 15ft.

[@kras_mazov]

Do you go to the basement, if you need to connect a thumb drive?

[@apalrdsadventures]

Depends. The basement is the same room I film in, so it's not inconvenient to sit with the machine during BIOS setup and then leave it for the rest of the testing since I'll be doing a basic setup on camera. For things like camera ingest and the like I can copy the files onto a network share from my laptop and then edit remotely over the HDMI bridge. But yes it doesn't pass USB storage traffic so if you need to connect a bootable drive you'd have to walk down there.

[@Heathfx5]

I’m surprised there was no mention of binary and their MoIP system. It’s extremely low latency, supports 4k, bidirectional IR, rs-232, HDCP and is powered with PoE. The box it does not check is low cost. It also takes anywhere from 300-800Mbps, so needs to live on a single switch unless you get into 10gb uplinks.

[@lilrex2015]

I just found your channel last night. I love how no frills, to the point and information packed your content is.

[@HenryLoenwind]

It should be mentioned that if you just want to connect to one or more computers with a (mini) computer, a software solution like Moonlight or Parsec is even cheaper (i.e. free) and provides keyboard/mouse/gamepad forwarding, too. That's how I got my gaming PC to heat up the basement instead of the house.

[@apalrdsadventures]

Moonlight and Parsec are definitely solutions for gaming computers, but it's not as generic and doesn't work for all sources.

There are things and tools that allow you to make an HDMI cable the right length: the right HDMI cable, HDMI connectors and HDMI crimping pliers. I have experience making 80m cable this way and it works well!

its a KVM thru Ethernet😊 and yes one of the many things you can do with a KVM (depends mainly on what features you got for your kvm)

[@arki3439]

Really love your videos, watched quite a few and implemented lots of similar stuff in my own Homelab. This video really got my head scratching. What do you think about removing the compression (and thus probably some more latency) from the equation? Upgrading to 10gig (or more) Networking would allow for plenty bandwidth (1080p60 would be ~4gbit). Going for a cheap used switch + a few thin-clients (+ m.2+pcie adapters) + a few sfp+ network adapters would allow for a similar, completely software based solution. Am i going crazy or is this a great idea (and way to rationalize a 10/40gbit homenetwork)?

[@apalrdsadventures]

That's essentially what HDBaseT does, except not over an Ethernet carrier. It starts streaming the frame as soon as it starts receiving it over HDMI, so it doesn't need to wait for the entire frame to compress and transmit it. In a completely software based solution, you still need to wait for the frame to be rendered anyway, but not transmitted over HDMI. As long as the encoder can run at 2-3x the frame rate you won't be introducing much latency, and even a little compression makes a BIG difference in data rate. Using GPU accelerated encoding, getting down in the 20-30Mbit range is pretty fast, and the decoding is a more straightforward process that can probably be done by thin clients.

unfortunatelly it wont run at least QHD on 144mhz monitor... only FHD@60, which today is quite limited.. also, if you put your computer in basement, you wont have access to any of its USB ports (except keyb+mouse), and if you use any USB Peripherals, like webcam and usb headset... well, you are out of luck.. these features imho is a must for solution like this.. also, having 2.5Gb port instead of 1GB would be nice..

[@Ata5ll]

in 2021 I bought a 8K fiber HDMI cable on Amazon, for a steep 158 euros, with some brand that was awarded with crazy revolutionary stuff for video over fiber. Yesterday I found out that the issues i've had since I bought it (trying to have use it on my TV in the past always had issues and hardly ever worked flawless) was broken. As it didnt even want to transmit PC to monitor information. Luckely because it was of a external seller amazon is like just sent it back and we give a 100% refund (holy cow?) So yeah... Looking for some 4k over IP solution now.. There's so much options and there's always one thing missing. either its only 30hz or its only HDMI 2.0 or even 1.4 etc etc etc And also while watching this video half of the options on Amazon don't even imply any way to work with a switch... Anyway Im going to keep watching because now youre going to throw my solution ;D thanks in advanced

[@Justfillintheblank]

Very interesting concept. I never would have even thought of doing it this way. I want to add my 2c for 7:36: UTP just means unsheilded twisted pair, what most ethernet cables are by default. STP (shielded twisted pair) is better if you want to run the cable through plenum, since they have shielding against EMR. A bit pedantic, but you seemed confused about it haha.

I have a 2960S managed switch and smaller 2960G-8 port switches on the other end. All are managed switches, and it would be good to place these on their own VLAN.

[@wzk921109]

I’d recommend optic fibre hdmi for long distance. Distribution box for multi sources & multi destination. Do not use HDMI over ethernet if you care about video quality. Over IP is not recommended either. Compressing 18Gbs to 1Gbs will lead to quality loss.

[@ZeIsAnEnemy]

It’s not solving anything until 4k available, real scenario - pc, gaming monitor, projector 4k, ps5, tv with 4k and only old hdmi cable inside the wall. So I’m sucking to have ability to get 4k on projector from ps5 because projector is mounted under suspended ceilings and cable can’t be replaced, I’m unable play ps5 on tv without moving. I want to play on gaming monitor widescreen type like Samsung odyssey in parallel with work side, without moving back console. The same story with pc, unable to have 4k on projector, unable to move pc to tv, able use with monitor only. So what’s a point of 1080p in general? Just kvm for pornohub from any device on the same screen in 1080p even in this case don’t enjoy it much. Someone pointed to birddog but their receiver and transmitter in summary about 900$, kinda too expensive.

Scenerio: I'm cooking dinner in the kitchen while others watch TV, I don't see TV and I don't have a place for a standard display in the kitchen only tablet size device. Suggested solution is nice for some applications but it still require extra hardware, also it won't work with laptop reciever, no option to connect HDMI source to it, so I'm not able to stream games from my desktop PC to my over 8y old laptop, while steam link works perfetly fine. I have a plan to explore option of using capture card with TV, connect it to some RPi3 I still have and see what happens, it's not a very powerful hardware but I hope I can put all of it's computing power into that one task.
