HAPPY NEW YEAR EVERYONE!!! Bring on 2020, it's going to be one hell of a year! We have some exciting things to announce next year, so keep your eyes peeled!

[@Vijaythalapathy28]

TechFlow we are waiting 🎉🎉🎉 happy new year

[@cmou8]

you too, thank you, nice testing video, what about to mode up the units, and may add some good antenna instead of the built-in ones,

[@Elbori239]

Type this in on amazon, i think these will work better and they agree 4k at 60hz J-Tech Digital HDBaseT 4K@60HZ HDMI Extender 4K@60HZ 4:4:4, HDMI 2.0 Over Single Cable CAT5e/6A up to 230ft (1080P) 131ft(4K) Supports HDMI 2.0 18Gbps, HDR, HDCP 2.2, RS232, Bi-Directional IR

2020 has really turned into one hell of a year!!!

[@felipebenchaya]

thanks for wishing a hell of a year, you made it!!

[@Dr.HouseMD]

Something about him reminds me of a tech Steve Irwin. I think it’s all the physicality. “If eye sneak up on it, here’s a jumpin’ pixel! Let’s get a bit closah! Oh he’s a sneaky lil’ buggah isn’t he...”

[@timboslice4019]

5:25 my dumbass thought you ejected a CD from your Mac book 😂

[@christopherrobinson387]

This is too funny

[@AraceaeFanatics]

This comment had me go look. Funny!

[@Amatshezi_events]

Dangit I had to look , n was fooled for a second, lol

[@scousej7187]

Been subbed for a while and you're so frickin switched on its amazing well done bro

[@LazyKingAus]

buying something to minimize wires only to have more wires than you started.

[@sankalpkhira5140]

Love your channel, and happy new year

[@paullangan193]

Could also be an issue with the usb NOT delivering enough power to transmitter?.

[@leandrohenrique3568]

Could you test a PC game? Will the transmission work well?

[@cormacobrien7638]

What is the TV and Soundbar setup you're using in the main room? They look insane!

[@josh.299]

Happy new yr!

[@joshdoktor8363]

3:23 Alex: what seem to be American Power cables Also Alex: *grabs the Australian plug adaptor*

[@LONGBOW-cy6hu]

this annoys me

[@Morenob1]

Would be nice if I can leave my pc or laptop in my room and connect it to my tv in the living room wireless. 2nd question is would bluetooth reach that distance? (Edited:) My Logitech K375s and MX Master 2 and Xbox controller reached the distance. Now I'm actually interested in the wireless HDMI if it's any good.

[@QuadcopterBoy]

Buys from the eu then says the plugs are American lol very close tho

[@Murvalous]

But they were American and not European plugs, you can see the flat 2 prong plug

[@Murvalous]

What would you recommend to go from pc upstairs to TV downstairs, is wireless an option?

[@bartycrouchjr.8831]

This video is awesome btw. Everything could happen at any moment. This video excited me. Your energy and your home-studio is an awesome and warm place.

[@C-ONE30SEVEN]

Ever heard of Chromecast ultra? Also your argument about not having to chase an HDMI down your wall with these boxes.....wouldn't you already have the TV's power inside in the wall?

[@CtrlAltElite123]

Happy New Year Alex!! Thanks for your videos over the last year.

[@johannesgoetzen]

When will it work without adapter on my laptop?

[@will300c]

would it not be better to do hdmi over cat 6? using hdmi xmitter/recvr?

[@dtwistrewind7361]

Can you solder a short extension of copper to the internal Ariel, a 2cm piece increased my Bluetooth amp distance but about three times and is stable.

[@JhorulAhmed]

Happy New Year

[@jeffytube198]

works Netflix or only Black Screen ?

[@rohittawani]

Happy New Year 🥳 bro ❤️🔥

[@Liehjan]

Can't you do the same thing with a Chromecast Ultra and share desktop?

[@hassanhussain1099]

When he said none of the others showed 4k. But they all legit said 4k

[@mrtunes1347]

I like the idea, what I got from this video is that it had potential but at the moment it's not currently worth it Would be pretty cool if they where smaller and you could charge the receiver part up. That way you could connect it to a portable/ zen screen monitor ( I want to do that because I'm lazy)

[@AnandakrishnanM27]

can hdmi over ethernet work over power line adapter?

[@cdav2199]

You've literally bought the exact same device basically but one is from a china seller who had advertised is 4k and at a higher cost lol. EDIT: Basically the 1st one on amazon is the same and was £169 , and you bought from banggood at $289, i thought you would've realised also and it is common with china, they can change USBs to show it can hold 64gb and not hold more than 2gb etc. Can make 720p in 4k technically too... *Just Be Cautious*

[@rayamundson8394]

NOW you have more wires than what you started out with.

[@theonlydarian]

4k at 30hz uses roughly the same bandwidth as 1080p at 60hz, this is why HDMI 1.4 spec (older laptops, pcs) support 4K up to 30hz. HDMI 2.0 is required to support 4k over 30hz

[@solomonbooth63]

Yep and that’s why you can’t use HDR on 1.4 spec

[@inverse_of_zero]

"roughly the same"? not even close. 3840p30 is literally double the data of 1080p60

[@Henery007]

That fireplace KZbin ruined my OLED.

[@gdwlaw5549]

Will this wok with HDMI arc?

[@forid200]

Tech flow quick tips?? 😂

[@BillygGaming]

Ikr 😂

[@speedracer123222]

For range sake I would just get a nyrus 1080p wireless hdmi. It has zero latency and it actually can go through wall a fair bit that ive seen(depends on how the house is)

[@unbekannternutzer8506]

Well you will always get some kind of pixelation with this. It has to compress the signal (x265 or sth. similar) in order to achieve the resolution.

[@rubsk1]

Happy new year Alex ......why do you talk with Big Pauses all The Time like Your talking To kids.

[@maxxirunner7219]

Close to the TV it works but working at 60GHz just a person or a wall that falls the transmission ... the 2.4GHz frequency transmitters are more stable ...

[@seanomight5401]

Editing this. So I mean, it waouldnt be fair to compare one device you find only off of amazon and make a myth or not video based on that without doing any research into if there are any other devices out there besides that one. Gotta do a comparison to see if its a real myth in this case i think. But i do like your videos.

[@chrisnicholson3363]

My question is this is 2022 does the new xbox series x work on the wireless hdmi

[@Ivar1231]

Nice review 👍🏻👍🏻👍🏻

[@GoldDominik893]

Nice intro ,happpy new year everyone

[@Muzik_Junkie]

I'm trying to find a solution to having my PS4/PS5 not wired to my TV. Only around a metre or 2 away but guessing when it comes to gaming the delay is much more noticeable.

[@B-DINO]

Nyrius has a 4K one. I never bought one but I have their 1080 one and it is truly 0 latency and works flawlessly.

[@yassinnajjar3044]

3840x2160 is 4K. It won't support more

[@anis-cq5po]

Wow even if it is running on 2k it's amazing, This why I love Chinese cheap goods when it works, e.g. Xiaomi , Oppo, Lenovo, Motorola etc

[@gaeljs9493]

It's very useful for projector setup

[@Gilbertvanhaasen]

That's exactly what I want to do because a wire is not possible in my situation. Thinking of buying this ...

[@DjadamGee]

No link for the product?

[@AraceaeFanatics]

His channel isn't new, yet he still can't get this part figured out.

[@transgrl]

Just pointing out, 4k hdmi when transferred over ethernet or wifi is never going to be true 4K as it's roughly 40gbps. You also lose out on HDR and Dolby Vision. Really not worth it at all.

[@jserenity]

I was wondering about this product myself

[@bennijr]

This is the Future i hope

[@Fishbait075]

What's the range like on 1080p? Did that manage to work from upstairs to downstairs?

[@xxcr4ckzzxx840]

It wont, because the 60Ghz Band has limited Range. What Kind of Bitrate u pushing is irrelevant at that point, because it cant establish a connection in the first place.

[@joewebber5956]

Keep up the great work. Happy new year

[@colinbyrne5018]

I’m not sure if this is correct could you not just use something like a fire stick 4K or a chrome cast ultra?

[@MovieCaveDave]

Try tha Skylarx, I’d love ta know if it can do Dolby Vision and HDR, press tha info on the LG so we can see what the signal is....smdh, thought ya knew tech ? ?

[@ricks3085]

Is M Dot your dad? 😂 proper look like him

[@GanetUK]

Is it legal to broadcast on the 60ghz range without a licence?

[@zamraqayum]

Yeah it's fine I pretty sure it's anything over 150is not

[@shawnheatherly9219]

Please elaborate a bit. I can't answer your question but I'm curious on why it would be illegal or why its a concern

[@GanetUK]

@@shawnheatherly9219 In the UK you need a licence to broadcast on most of the frequencies on the radio spectrum, there are exceptions for certain frequencies but usually there is a limit to the power you can broadcast it at without said licence.

[@shawnheatherly9219]

@@GanetUK that seems strange. If youre only broadcasting from the inside of your home to other devices in your home why would there be regulations like that?

[@GanetUK]

@@shawnheatherly9219 I agree but regulations don't have to make any sense, I think there is an EU regulation that means banana's have to be grown straight (not sure if it still applies), regarding the signal strength it's likely so it doesn't interfere with others using the same frequency, regarding the other frequencies it is likely to stop things like pirate radio stations and signal blocking. I would not worry to much about it as any wifi device you buy in the UK (unless you hack it) is restricted to only broadcast up to the signal strength limit.

[@mprie4]

maybe in the future it work even better

[@alimugeni5357]

where both parts receiver and transmitter being power 5volts 2amps?

[@thefamilymanshow]

Ali Mugeni wonder about that too

[@EllieMappin]

Then you realise chromecast ultra has kinda the same functionality with being able to stream another screen to a tv in 4k.

[@LONGBOW-cy6hu]

and airplay, and a normal cable does too

[@EllieMappin]

@@LONGBOW-cy6hu haha yeah

[@tcntad87]

100Mbit/s ? Easily done over 802.11n. You get interference beacuse 60Ghz

[@KillYou360]

annnnnnnnnnd noob alert. Just so everyone knows, most tvs don't support none native resolutions. That is why 4096 did not work. And if he knew what he was doing, he would've know that it shouldn't have been the first resolution to test with.... 3840x2160 is the native resolution of nearly all 4k displays.

[@niczoom]

Haha, agreed. Exactly my thoughts whilst watching this. He's just adding unnecessary drama.

[@christovercomers]

What's the name of this transmiter

[@maxtheinvincible1925]

The power cables are AU That means Australia

[@LONGBOW-cy6hu]

what annoys me is he said the plug for the usb charger is American when its acually Australian. Banggood is also an Australian company

[@speedlink7998]

Very Nice......

[@razielmcr]

4K at 30fps 8bits is 10.2Gbps through HDMI 1.4.

Lol, I am having the same desk (under your macbook) in my living room :D

[@kito1san]

Watching this video on youtube 4k 2160p. Works fine.. However, some smoke are coming out. Is this normal?

[@SamRobertsonYT]

clicked this just to comment a tip.. work on the thumbnails chief! Exciting title can't sell a video with a lifeless thumbnail. Left me thinking meh wireless 4k probably works now what do I wanna watch

Skylarx wireless hdmi review

[@garethdawson9746]

now introducing the new Wireless Xbox

[@chanj8426]

very informative THanks. but the device seems not useful. maybe I'll be better to wait until the device get fixed whole limitation.

[@mrnait5169]

Maybe the usb from pc or tv is not giving enough juice to it. Just like phone charging man

[@RyanArmstrong89]

man the level of knowledge you dont know astounds me. DCI 4K isn't regular 4K. you should know this with the amount of top level gear you have.

[@matthewshaw1995]

not sure why this comment has 6 likes dci 4k is newer and higher res than UHD DCI 4K is 4096 × 2160, while 4K UHD is 3840 × 2160 see google reference www.hireacamera.com/en-gb/blog/motion/technical-jargon-explained-what-is-the-difference-between-ultra-hd-uhd-and-4k-dci/

[@mrb3991]

Hi would it work better with an high speed hdmi data cable

[@LONGBOW-cy6hu]

it would work better if you dont even buy this and use a cable as intended

[@nickevans8977]

Does Alex even know what compression is?

[@TheGaggenau]

Nick Evans no he clearly does not.

[@BlueKnight87]

Those plugs weren't American; they're Australian/New Zealander!

[@714Wajihali]

Great video! I'm sorry you didn't make your money back though

[@malmstring]

I don't understand the premise for this video. 1080p/120 and 2160p/30 is within same HDMI specification - HDMI 1.4. Why is the reviewers premise that it should be so much harder to project 4K/30 compared till 1080p/60? Is he even aware of the HDMI specifications? Is this video a spoof? Did I miss the joke?

[@lupsik1]

Didnt watch the video past the 2nd minute yet so i might take my words back but I felt i need to reply. 1080p is is about 2 million pixels, 4K is about 8 million pixels so 4k/30 compared to 1080p/60 is 2x more bits of information to transfer. 2 times more is not ridiculous but its a lot more, for reference right now we double processing power of consumer cpu's about every 5 years. The video signal going over an HDMI cable needs to be in sync with the graphical processor that sends the data, afair it determines the frequency of updates and expects to have new data in those even intervals if the frequency fits its specification. To allow this wirelessly the receiving device must have at least a small buffer for when a packet gets lost and needs to be sent again etc. so that you dont experience stutter, flickering etc. If the wireless connection isnt able to fill that buffer faster then its being emptied then you're missing the time windows for when the image was supposed to be displayed and end up with a black screen, then some image and black screen again and so on. My point is, the hdmi specification might allow 4k/30fps data to be pulled from the receiver but the wireless connection has to have enough bandwidth to provide that data on the receiving side. Sorry for the terrible explanation, but I dont understand why you're talking about HDMI specification when the discussed problem is sending the raw uncompressed data wirelessly which is a whole different thing from f.e. streaming compressed 4k video from netflix.

@@danielplusben is it? Oh

[@bartycrouchjr.8831]

I prefer external hdd and HDMI cable connection for watching 4k movies.

[@JohnWeland]

Yeah, 60Hz, I don't think 30 meters is legit. There were some works being done for wireless VR that were doing to use 60Hz (Wireless AD) they only could promise same room/open room coverage. That is pretty cool though.

[@James-ns6jm]

Bit different to VR mate. As it's essentially two screens and it needs to be at a higher refresh rate than 60Hz as it will cause motion sickness very quickly.

[@scotchegg6422]

That works about as well as your DIY skills

[@prosperityokechukwu1503]

can I use this for a camera in my church

[@Gkokkinakis2]

It should work

[@GeorgiaDawgAthens]

Excellent review with, possibly, some perceived short-comings contributed by some commenters. I need to connect my TV to an upstairs device ~10 feet directly above. Your evaluation of this device is most helpful. Disregard the comment by riko herlambang. I enjoy your enthusiasm in presenting this review.

The only point of this is that cleans any clutter or wired mess.does it work from downstairs to upstairs doubt it.

[@samihyppia8472]

Wired or cluttered mess??? What the hell are you talking about dude? This thing uses USB + HDMI cable + has a huge large box!!! No way in hell is this less "cluttered" - on the contra it has more cables+box compared to 1 hdmi wired cable. The only thing I see here is that if you really can't have wired connection to another room - then you have no choice but to use this - otherwise - it sucks !
