No, but I don't really have a means to, I've basically only ever used Dell LCD's. Also, at this point I am not educated in the differences in panel types.
Fair enough. Just curious because I've almost exclusively used TN panels due to them being cheap and large and good for gaming, but did end up with some sort of PVA 19" due to a packaging error for a Black Friday special a couple years ago (box said 1440 x 768, which would have been a TN panel; actual product was 1680x1050 and I later worked out that it was a PVA panel of some sort).
There is some variation between the quality of TN panels on the market, but AFAICT the age of the manufacturing makes more difference than brand or screen size. The benefits of PVA and IPS aren't obvious to the casual user but once you get into digital photo and graphics editing, and see how a photo edited on a TN panel can significantly change in both brightness and color rendition on a better-quality panel, the difference becomes meaningful.
At my workplace some of our drafters and engineers use a panel very similar to yours, though, so they're at least good enough for that in addition to standard gaming fare.
