I was trying to recreate my desktop, I have 4 2560x1440 monitors and 1 4k core monitor. Even with direct connect on my occulus to my laptop with a 2nd wifi, I was getting 5-30ms latency and lots of hiccups. It wasn't pleasent, definitely not as pleasent as just setting up a travel dell 2560x1440 monitor and nothing on the new 4k 17" I just picked up for $300 on amazon.
The gpu on my laptop was also on fire and the machine was sluggish due to gpu issues, thermal issues, network issues.
It was also a less pleasant and less quality experience than real physical monitors. I also tried it with my index on the beast desktop I have that has those physical monitors turning the monitors off and putting in dummy plugs (same as laptop).
It sucked, my neck hurt, it was laggy, hard to position monitors which I had to do every time I set it up, and the resolution sucked compared to a physical monitor, and don't get me started on fots let alon comparing it to 43" 4k monitor.
I spent a decent amount of time in discord with immersed trying to get it to work. It's just not meant to be currently. And for the same price as a occulus, same weight, smaller footprint (the occulus is huge in a backpack, a tablet monitor is just and extra half inch of laptop), I get a much better experience. Also my neck doesn't hurt, I can see the world, and it's much higher res.
