4k UHD Headless adapter review for Mac or PC

[@pparks1utube]

For those totally stumped on what this does, it's this. When you run a device like a Mac headless (with no monitor attached), the OS knows you don't have an attached monitor. When you remotely connect to the Mac from another device, since the Mac knows a monitor isn't attached, it gives you a very basic resolution you can connect to and you are stuck with it. The dummy plug does nothing more than fool the OS into thinking an actual monitor is attached and thus when you remotely connect to the Mac from another device, you will now see a whole bunch of resolutions you can pick from. So, it does not wirlessly send your display somewhere, it doesn't turn anything that couldn't previously do 4k into 4k, it doesn't give you additional monitor support. It's only useful if you have a computer on a shelf or a rack without any monitor attached, and it only provides ability to see additional resolutions when you remotely connect to it via something like team viewer.

Okay, still not totally clear on this. OWC advertises their NewerTech Headless plug as working with PC, Mac and Linux. Using this plugged into the Linux box, will I be able to access the Ubuntu Graphic interface when I ssh into from my M1 Mini? Meaning, I no longer need to have a monitor plugged into the Ubuntu box? I already run ssh between all my machines now, but that limits me to using just the command line to work on the Ubuntu box...

Thank you

[@0ngoing3xistence]

I have a Samsung monitor would it work on that? I’m trying to connect my gpus

[@paulmaister]

Thanks for the clear explanation

[@COMPTROL]

Thanks pparks, I was searching for the use of this. ​@@dennismosercreativearts no, you need a remote desktop app to see your desktop. In video vnc viewer app is used.

[@bangdollarsign]

Hold on a second, I don't see a GPU listed here, just the onboard video, which it would have been using without the dongle connected. I'm not saying nothing was achieved, but the same video hardware was in use regardless of the presence of a display.

[@maqui1814]

Ohhh, I think I need one for my laptop. There are more GPU settings you can set up with external monitor connected.

[@ramidaoud3776]

Why not Betterdisplay app?

[@rackzpsy]

what's the purpose of the connector?

[@NotBROLL]

I got one so I could use my old PC remotely without needing a screen connected (via Parsec, for free). It basically fakes a screen being connected. There are several other use cases.

[@tabithaledbetter5370]

@@NotBROLL can you elaborate on using remotely and the other uses? Ty

[@NotBROLL]

@@tabithaledbetter5370 Remotely meaning you can have a desktop PC in another room/house, plugin a keyboard/mouse and this HDMI adapter, from say another room/house/location, with e.g. a laptop, you can then remote into your other PC (via the Parsec remote software in my case). Main reason to use this adapter, is so you don't need a real display plugged into the remote PC, this adapter will also "fake" a bunch of different resolutions, were as a plugged in screen would be way more limited.

Is there one we’re you connect one into a gaming console or anything and then you plug the the other one into a tv or monitor and it displays it from far away where the console is

how to setup multiple display wirelessly?

[@wojciechzdzarski1838]

Use VNC protocol. Your transmitter should be VNC server, your reciever VNC client.

[@dk-ku4tc]

My laptop supports 1920*1080 60hz, but when I trythat resolution to see.my.EGPU dummy HDMI screen my mouse lags and I get low Fps, any fix

What resolutions appear on the scaled menu? You can set there a 4K resolution or is this dummy not that effective?

[@FrimleyComputing]

Hi and thanks for your comment. So far I've tested with an HD 1920x1080 display with VNC Viewer. It scales up to full screen with no issues at all. The resolutions it supports are: 3840x2160 @60Hz(with HDMI2.0) 2560x1440 @60Hz 1920x1200 @60Hz 1920x1080 @60hz 1680x1050 @60hz 1600x1200 @60hz 1600x900 @60hz 1440x900 @60hz 1366x768 @60hz 1280x720 @60hz 1024x768 @60hz 800x600 @60hz I paid £5.99 for it on Amazon with free delivery. One of my best purchases and I'm really pleased with it - previously I was limited to a 1280x1024 or 1024x768 choice via the Mojave display options - now at least I can have it running at full screen with no blurring! :-)

[@aonezzzz]

Ian Robson also with the dummy the CPU has less work to do! I had some problems with this in Mac OSX 10.7 and earlier, it got frozen if no monitor was plugged. It’s great to have such cheap HDMI solution now. Thanks and enjoy your new Mini :)

[@Dragonkill-music]

what software do you use to connect remote Mac ? is there something free ?

[@cmlosaria]

I have one HDMI port on my laptop, if I plug this in at that HDMI port, how can I now use my second monitor? or because I have a second monitor, this isnt necessary? or should I buy a hdmi splitter so from 1, it becomes 2 port and I can plug this and the monitor? I am confused what this actually does.

[@NiallOHagan]

I too am completely stumped on how this thing works... I mean no offense or anything...I'm just totally lost on what's going on lol

[@100Bucks]

I got one. There's two ways to use this. If your computer doesn't support 4k, it will infact give you a 4k display. The other method is for remote use. In windows display, pick the fake HDMI and your computer will go completely black. Only way to access it is with a app like parsec or TeamViewer. If you wanna change it back for upscale use only. You need TeamViewer or parsec to change windows display back to duplicate these displays. Once you make display changes, it takes like that forever until you access it remotely. I had to share this info because some of you will use this, get a black screen and assume it doesn't work. It 100 percent works.

Nice explanation, gives 4k on non 4k computer.

[@pparks1utube]

Not at all what it does.

[@100Bucks]

@@pparks1utube I actually bought one and it does in fact upscale. You have to keep it set on "Duplicate these displays" inside windows. If some how you get black screen using this. You must access your PC remotely to change it back to duplicate these display so it upscales properly. I use parsec app for remote use. This device combined with Lossless Scaling is great together. Upscale 720p video games to 4k on a weak GPU with the help of a dummy HDMI 😂

[@BadAimPH]

Nice video

[@plepethnaut9548]

Can this device used to stream game remotely?

[@FrimleyComputing]

It can but NOT recommended as all video and graphics content would stream via VNC so I would connect a monitor to be able play games with no lag. Hope that helps.

How do you know what your computer is doing while using this ? Maybe a dumb question but I’m mining and occasionally every day or so it might crash and I have to restart, if you use this adapter and can’t see anything how do you know what your computer is actually doing
