XEYOU DisplayPort Headless Ghost Display Emulator for PC 4K DP Dummy Plug (fit Headless 3840x2160@17hz)-3Pack

I run a headless Plex server and wanted to make sure I didn't have any issues with remote desktop; others have reported that without a monitor actually plugged in, the GPU (discrete, not onboard) won't output properly in regards to hardware-based transcoding. Not only do these work great, but they report to the system as a 4k60 monitor (unlike the cheaper alternatives that just report as a 1080p display). Not only that, but they're DisplayPort which is necessary for the Quadro P2200 my server utilizes. Aaaand you get THREE of them. If I accidentally... I don't know, swallow one (kids, don't swallow electronics dongles!), I'll have two more to swallo- I mean use.

These were perfect for my work PC that was brought home at the beginning of the Covid 19 crisis. My work PC had 3 displays connected to it when at work. In order to use the 3 displays on my home PC while using Microsoft Remote Desktop, I needed 3 of these dummy plugs.

These work to simulate a 4k display so that you can remote in with gpu hardware acceleration to a headless machine. Hot pluggable as well. A little difficult to release the display port connectors as the spring clamp is a bit tight and located on the bottom with a standard gpu orientation.

in my case i needed remote computers to think they had two monitors, and now they do

Works as advertised.

Works like they should

I use these to keep the graphics card working on PCs running digital signage. Without them the displays do not turn back on when power cycling the PC.

Works as expected!
