XEYOU HDMI Dummy Plug Display Emulator for Headless PC 4096x2160@60Hz, 3 Pack 4K Virtual Screen

I had a lot of trouble trying to get Steam streaming to work without having a monitor attached. Without a monitor attached, every once in a while, the game would actually start properly with sound. But generally it wouldn't, or at I'd have picture but no sound. This little emulator has worked out perfectly. I have my main PC set up to log in automatically and start Steam. When I'm ready to stream a game from my laptop, it's totally ready-to-go. No issues ; full resolution and sound. I ready setting up TeamViewer should work as well; there's some magic there. However, I didn't want to rely on another piece of software. With this adapter, I turn the PC on and it's good-to-go.

仮想PCでGPUパススルーした時の画面表示用に購入しました。4K@60Hzで無事動いています。しかしDP用の4K@60Hz対応ダミープラグってものがないですよね、HDMI用はいっぱいあるのに...。なんでなんでしょう？

Son perfectas para el Trabajo desde casa, utilizas los recursos de la computadora de tu oficina sin tener que tener conectado el monitor.

I cannot believe that I have been in IT for over 30 years and didn't know that these exist. I was literally thinking one day "I wonder if someone has come up with a dummy HDMI connector that tricks the server into thinking that there is a high-resolution monitor attached for better remote access" Well obviously someone was way ahead of me. These work perfectly and make things much easier for me on some older machines that revert to 640x480 when there is no monitor connected when it boots. Now when I connect with TeamViewer, I get a full range of resolution options to choose from, making remote work SO MUCH EASIER.

Needed a few DELL towers to boot to NVIDIA cards without monitors. Plug these into card and system boots up fine. Low cost, does exactly what I needed.
