I'm in the market for new monitors. Mine are now the better part of a decade old, and they're showing it.

I'm looking at IPS screens. I notice a lot of people complain about grainy anti-glare coatings. Since I'm likely going to be saddled with whatever I buy for 5+ years, I want to avoid anything less than perfect.

What should I look for to identify the distortion from an anti-glare coating, what tests should I run on the monitor, and how should I avoid it? Is there any way to really go compare it on televisions out in the wild/Wal Mart/Best Buy?

Thanks!
