yeah what I’m looking for is a little easier on X11 based DEs.

But HDR brings me to Wayland/KDE, and there seems to be a tool I missed last time I looked to do virtual monitors

My problem there is it only solves half of a computer. Audio/visual sure, but not input or control.

I’ve started a small collection of ones trying to get HDR 4K@120.

I just found https://www.amazon.ca/AviWrap-Virtual-Emulator-Headless-Supports/dp/B0GHWG97MR

Might give that a try as well.

My basement to my TV is beyond bluetooth range. I need something network based.
