HDMIダミープラグ 4K@60Hz、バーチャルモニターエミュレーター 1パック

Does as advertised, only complaint is that the light located on the back of it does shine a bit bright and has woken me up multiple times at night, but that is just nit-picking. Other than that, works well for it's price.

While I only needed one dummy plug for a headless Linux server, I purchased this three pack due to its value. After extended use I have not had any issues with the one I have installed tricking the server into thinking an 4k monitor is attached and if I do I have two more as backup.

doesnt seem to produce good output on crd or rdp.

I've been using my machine headless on Ubuntu with the NoMachine server, but wasn't able to use any GPU acceleration in visual apps like Blender due to the lack of a physical display. Ubuntu also had some quirks where my Snap apps won't show in the Super menu on a virtual display. I plugged one of these into the machine and voilà the computer treated it just like a physical display, so I got the hardware acceleration capabilities I wanted and my Snap apps worked as expected.

i use these for game streaming. out of the box the resolutions only support 60hz, but they can be modified with an edid editor to get higher frequencies. i did this so i could get 90fps on my steam deck while streaming.
