4Kのリモートデスクトップ用に安定して使えてます。

Perfect, does exactly what I needed. Allows me to vnc into my pc without a monitor attached without needing to turn of direct draw in realvnc settings.

I used this solve an issue with Steam Remote Play. I wanted the beefy machine in the livingroom to stream 4k to a laptop connected to a 4k TV in the home office. The only way I could do that was turn on the projector in the living room, which defeated the purpose of remote play to begin with for me. Here's my setup so you can understand the problem. I have beefy system in the living room connected to a 1080p projector w/ surround sound, projecting to 120" screen. I usually use Nvidia's DSR to render to 4k, but output it to 1080p, naturally resulting is a more detailed (but naturally not as good as a native 4k display would be) 1080p experience, that looks really good at 120". In the home office, is my lenovo 2-in-1 i use for school and basically everything on the go. It's connected to a 4k HDR TV. If the projector in the living room is off, then Steam Remote Play will only stream a 1080p signal to the laptop in the office connected to the 4k display. In fact, it's almost like DSR is disabled once the projector is turned off because I can't even select any resolution above 1080p. If I turn the projector in the living room on, it's like DSR works again and I can pick resolutions higher than 1080p, including 4k, and stream at 4k to the laptop in the office. I don't want to burn up lamp hours on my projector just so I can play a game in the home office at 4k. I've researched a solution to this on and off for over a year and came up with everything from modifying EDID, to other stranger methods. It's seems like it would be such a simple fix, but alas, it is frustratingly not. Until now. I found out about devices like these. Put it into a spare HDMI port and walah. As acts as an active display. This worked great. I mirrored my monitor to this fake display and now even with the projector off, I have the option to stream 4k to my laptop in the home office. Wish I had discovered this a year ago.
