IT seems that most IPS high end monitors specifically the Asus ROG PG279Q have alot of back light bleed. Many reports of people returning monitors and that it is a lottery getting one with minimal BLB. It seems that even without BLB there is a IPS glow. I know IPS is better picture quality but is IPS THAT much better than a high end TN panel? Is it worth the frustration and IPS glow and price increase? I don't care about viewing angles at all. Only picture quality.
"Picture quality" is too broad for this discussion.
IPS = Very good colors, medium response time / hz, poor blacks (IPS glow and/or BLB), great viewing angles
TN = Average to bad colors, fast response time / hz, average blacks, bad viewing angles (colors and blacks look very bad off angle, so TN turns to bad across the board except HZ when off angle)
VA = Good to very colors, slow response time / hz, very good blacks (e.g. contrast ratio), medium to good viewing angles
that's the quick and dirty.
It's 100% about what you prioritize and what you use the monitor for. If you need black blacks then don't get an IPS. If you want vibrant or accurate colors, you want IPS.
So far the best "no compromises" monitors are high refresh rate, high resolution, 8 or 10 bit VA gaming models. The compromise is they are extremely expensive, still more ghosting than IPS or TN but not really enough to notice for most people.
I think it's telling that every top of the line model of 4k UHD TV out today (except OLEDs of course) use VA.
