HDMI Dummy Plug 4K Headless Ghost Display Emulator Compatible with Windows Mac OSX Linux Support 4kx2k 1080x2160 for Computer Desktop (fit-Headless, 2 Pack)

Work vary well

I have an M1 Mac mini server that runs without a screen. With screen sharing, the default resolution was disappointing and could not be changed. Text and images viewed while screen sharing were all rather poor, lacking in detail or difficult to read. Anything animated became a little pixelated, and this included dragging windows across the screen, or menu items dropping down. With the dongle fitted most of these issues disappear. Text is pin sharp, images are detailed and animations look much better. You can still tell it's a shared screen, but it is altogether improved. Recommended. I've shown a screen-grab taken with and without the dongle fitted. Note in particular the quality of the text and detail visible in the image. The M1 Mac mini is running Tahoe, my desktop machine an earlier version of OS X.

I bought this product to see if it would give me control over the screen resolutions available to a headless M2 Mac mini. It did precisely that so overall I am happy. It did not produce quite the range of resolution choices I was hoping for to make best use of my ultra wide screen on my controlling Mac, but it is still very useful. For the money it is great.

I was having issues with my GPU not rendering properly when I turned my screen off and wanted to use Remote Desktop. I bought this to set my PC in duplicate mode, my standard display on HDR 240Hz and this adapter running at 60Hz. So far so good, and came with 2 which I’ll probably fit in another PC at some point.

Its useless. I couldn't see what he does.

Enabled me to remote into Windows 10 machines reliably.

Works well simulating a 4k screen.

Not a lot to say except they work as advertised.

Does at it says works great..

If you need one, you probably already know what this is, but if you are buying for someone else who needs it, just know that the DTECH HDMI Dummy Plug works perfectly for OBS if you're looking to use it with OSC. There are other uses for it such as for Twitch Streaming, Crypto Mining, and gaining remote access to your computer at a 4K resolution, but we're only using for OBS purposes and can safely say it works great. It's simply plug-and-go, and at $11 for two dummy plugs, it's a bargain. Overall works well without any problems.

I specifically needed a dummy plug such as this one that offers 1920x1200. The first two brands I ordered off Amazon advertised the resolution I needed, but were not actually programmed to provide that resolution. This one here is the first of 3 different brands I ordered from Amazon that actually has the 1920x1200 I needed. 10/10 A+++ product. Thanks!

I use an old gaming computer as a plex and data backup server and this lets me use that computer without a monitor. The outer metal casing wasn't glued on super well so it came off on one of mine, but frankly it doesn't matter. I've had no functionality issues with this.

I bought these dongles to make it possible to remotely connect to a Windows-11 box from a Win-11 laptop. When a physical monitor was connected to the machine, the RDC worked well but it was basically unusable with these HDMI emulator dongles. The screen would show up but mouse clicks did not work well and if the start menu was opened it could not be seen. I tried several different resolutions and refresh rates but the behavior was the same or worse. I am using NoMachine, which has worked for me in the past between Windows and Linux systems with actual monitors. These HDMI emulators were a waste of money for me.
