Looking for a non-IPS, 27 inch, 2560x1440 monitor

I found that TN based panels tend to turn dark purple when the pixel is off. I have always found this distracting because you see grey getting darker and darker then it turns purple, not black.

Backlight dimming is much less impressive than it was supposed to be by this time. Now even most TV's use edge lit because consumers want thinner(form over function is very popular). full array local dimming(edge lit TV's can still dim sections just not with such accuracy) was the ultimate in black level control for LCD panels. While it was at all the trade shows years back it has almost disappeared.
Something like this. It takes more power because it requires a special controller(cpu) and also should be used with better led's if we are ever to get better color reproduction. Few people realize that the back light plays a roll in color.

Moving on.

I find this screen has some of the better dark color reproduction I have seen in years(this is actually impressive for a screen that can NOT dim the backlight in any way being as dark as many screens that have to dim the backlight. This thing is also a pig on power as a result) and they do not change colors(dark purple is not an issue for this screen). I can see all intended things in the games I play. When they have a calibration I most times have to turn down the slider.

The off angle contras actually allows you to see things you may not want to see. Dark scenes on compressed video(all modern video is compressed) will actually show you more compression artifacts off center than in front, the darker colors just become brighter.

I am so picky with monitors that I bring a laptop to the store to shop(Funny thing is a store associate once told me that image on a monitor has nothing to do with the screen and all to do with the video card driving it. Yeah...sure, my video card makes a cheap monitor color band....). It is packed with various images to check for color banding/dark and light color reproduction and I always make sure that dynamic contrast can be turned OFF. I do not want the entire heads up display to get darker in a game when I enter a dark room and then to get super bright when I leave that room. It is one of those things that I never want to use and seems only designed to sell products on a feature that falls flat when the screen has to display dark and light sections at once.

Unfortunately, the quality of monitors is all over the place. In the image above you can see the one screen clearly has trouble with darker colors(the screen can do dark[very dark], it just mashes a large section of dark colors into one single color) and the camera sees much better than I can because it looked even worse in person. Even on the S-PVA thing are very dark, but dark as they should be I think(to see much more would show all kinds of artifacts in the game it self).

Please note that because this is a wide color monitor(high 90's in adobe RBG compared the the low 70's of the sRBG setup), things do not always look the same either. Some users may be put off by this because some colors can be over saturated. Seeing as how over saturated many screens ship, It has never been an issue to be(just sucks that very little takes advantage of this feature.).

My overall recommendation is to check out screens locally because they seem to have quite a variation from screen to screen(even from the same maker. They had a Samsung TN 23 inch screen that had almost no color banding while the 27inch of the same screen family had quite a bit of it.).
