Not GP but I use Virtual Desktop with decent home Wifi so I can max out the quality settings.

(I can even work remotely if both sides have very fast broadband)

One caveat - this is an alternative to using a laptop and my eyesight is somewhat flawed due to middle age. If you're a 20-something with perfect vision and an addiction to 4k screens then this is probably a step down. For me it's on par with my non-VR experience.

I’ve done the same with a q3 and virtual desktop for a few weeks and hours at a time when I didn’t have a good monitor. I could run a 4k screen after tweaking the settings a bit. (And using a dummy hdmi plug so an external monitor was not needed)

It was best curved and large (and angled down a bit) so that I use it like it is 4 1080p screens. And move head to see each (and a bit more) sharp.

The newer version (tested briefly) lets you arrange several virtual monitors wherever. Not as convenient/sharp as a large 4k tv/monitor on my desk, but for a backup monitor and mobile it was great. I’ll give it a shot again.

I use Virtual Desktop over home WiFi. I don't even really tweak it beyond that, but I'll sit at an empty desk with a wireless kb+m and a few virtual monitors. Works well!
