I don't know what issues you're experiencing, but I recently purchased a new monitor to replace my old VA panel monitor. My Viotek monitor was nice, although I found that I had some issues with eye strain when reading text.
The panel was the most important bit to me, although I had some other requirements for the "right" monitor for me. I like my monitors to be slightly curved and 32 inches with a high refresh rate (i.e., anything 120hz and above is fine with me). Something I wanted that my old monitor didn't have was a glossy finish for those "deeper blacks", as I had an old monitor that really liked 6 years ago that had a glossy finish.
Anyway, after looking into it, I ended up buying the Alienware AW3225QF as it ticked all the boxes. It's a QD-OLED monitor and I can say that it's very easy to use my monitor for long periods of times without suffering any kind of eye strain like I used to with my previous monitor. The only issue is that it is a bit expensive at $1,200. If this is too high for you, there are plenty of other nice OLED monitors in the $600-$900 price range, although they're 27 inches and have matte finishes on the screen.
