HDMI Dummy Plug Headless Ghost Display Emulator/Virtual Monitor Compatible with Windows, Mac OS, Linux[Fit-Headless 1920x1080@60HZ] 3 Pack

Do the job and I can control my mac mini used as server without the need of a screen monitor

Silly this is required to have a headless Mac without 3rd party software, but it works well and is affordably priced.

As advertsied.

I am using my old desktop to run a plex server, file hosting, and some other things. I noticed weird issues when I tried to connect to it via remote desktop, also some other issues w/plex too. That's when I discovered that video cards/windows don't always play nice when you don't have a monitor plugged into it. Anyway, bought this, plugged it in, everything working as expected now.

Used this plug on my server to get my GPU passthrough to work with ProxMox.

Those devices (pair of 2) had been working for like 3 days and after that suddenly stopped. After investigating what’s the issue my RTX card got burned at the HDMI port because of this “device”. Don’t plug it to your computer.

I've purchased similar products before, but they're small and wander away when not in use. I thought this was similar, but found the connector does NOT accept a male HDMI cable to plug into the plug. If you were to use this from your DVR, you need a splitter to be able to have output from the DVR. Other than that, works great.My TV supposedly supports 4K, but when I use 4K input, video is very irregular. I used this to force my DVR to be 1920x1080 since video wasn't stable at 4K. Every time the DVR downloaded an update, it reset to 4K, so I needed to correct it in flashing video. Instead, I needed a 1-3 splitter instead of my 1-2, but the video is stable. DVR is now sticking to 1920x1080.

Works perfect with an ASUS 690 motherboard using integrated graphics.
