I ended up trying a couple of LG VA monitors. Both have been a major improvement. Not perfect eye fatigue relief for me, but much much better. I am thinking about trying out a Samung VA QLED just to see if there is any major difference to what LG offers. The two I have tried from LG are the 32UD60-B (4K) and the 32GK650F (1440). The panel quality is worse on the 4K, but I still prefer it for it's higher PPI for text sharpness. I am running it at 180% scaling and at a viewing distance of about 3 feet, which makes most everything of a very comfortable size.
Also what I have tried along the way is switching back to my IPS monitor, which ends up giving me eye fatigue sooner or later. And I tried out a newer gaming TN monitor, the Dell S2716DGR. It also gave me eye fatigue. To really find out if the IPS and TN were more fatiguing than VA, after eye fatigue began to really set in, I swapped in the VA, and the relief began right away, and within around an hour or so my eyes were back to feeling much better. And it is even better if I use the VA without having first used the IPS or TN monitors. I would say that the overall improvement is major, where instead of getting painful eye fatigue, my eyes eventually reach a tired level and stay there. It feels different than fatigue, where my eyes ache and my focus begins getting blurry. And the general look and feel on the eyes of VA is warm and soft. If I had to put a number on it, I guess I would say that using a VA is a 75% improvement, enough that I can get on with using a computer for text work and everything else without worrying about getting eye ache.
Any way, VA is definitely worth a shot.
