true although I use TN now, I used IPS. Both are crap in terms of blacks, but for gaming I'm afraid TN is better(from personal point of view). Especially black equalizer feature in games helps a lot. And no more IPS glow...that thing make me nuts...

Both of you guys must have used bad examples of IPS. Have 3 IPS displays and 2 of them have exceptional black level performance (measured and calibrated @ .12 -.14 cd/m2) and minimal IPS glow which can only be seen very faintly at off angles and on very dark backgrounds. Also had a premium grade 120hz TN (Samsung S27950d) that cost more than my IPS units and its blacks paled in comparison. It excelled only in motion and fast paced gaming, but would not go back to it vs my IPS, ever. VA can get lower measured blacks (but often with black crush) which results in higher contrast levels, but beyond certain levels there are points of diminishing returns. Like all displays, there are good ones and bad ones regardless of panel tech used. Ones personal experience should not be used to make sweeping judgments against one panel tech vs another, but there is a reason why IPS type displays are used by majority of professions that require top color accuracy and why TNs are not. Things may be changing on that front though as some TNs are beginning to use 10-bit displays that may one day rival IPS performance.

VA ? omg NO !!! Have you seen those horror movies where people go into the woods and crazy people kill them in horrible ways ? That's what you'll experience if you buy a "gaming" VA panel. Do yourself a favor stay away from that technology it's not able to handle anything in motion at all ever ! VA produce VERY obvious dark/purple trails & the reverse ghosting is INSANE, it's not a faint ghost its a perfect black or white clone of your moving item it's not a monitor video but I don't have much more time so it'll do: https://www.youtube.com/watch?v=ikGOqdBGUDY that's what an Acer Z35 predator will give you be it in 200Hz G-Sync or even ULMB the only thing that will change is the size of the pruple trails ranging from I'm not joking 1-3" long...actually in one of the modes I had an half screen long trail, half the screen of a 35" monitor 😛uke2::banana: I tried 3 others all were the same, went to check TVs in supermarkets, same purple trails if less than the awful Z35, VA is totally unfit for gaming or anything really other than being a digital photo frame... I also tried a few IPS screens and if not great even at 60Hz and from office monitors I would still play on them rather than see those unforgettable purple trails. I currently and from the look of things will still have it for several years an ASUS VG278H that with the lighboost hack http://www.blurbusters.com - can run this test @120Hz with almost zero ghosting I faintly see if I put my head at less than 1" of the screen a lighter black shape following the ufo but it's not noticeable at a regular distance and I have 9/10 10/10 vision http://www.testufo.com/#test=framerates - I can also READ the text on this http://www.testufo.com/#test=photo&photo=toronto-map.png&pps=1920&pursuit=0&height=0 and see no motion blur whatsoever being a TN it has horrible blacks, more like grey actually but still NO motion blur it's priceless if you don't have or seen an ULMB monitor in action you do not know what a gaming monitor is, it's impossible to go back once you have one. p.s. CRT were blurry as hell BUT they had real black depth as in reality like, go outside on a bright night and if you stay away from light sources after a while you will start seeing a lot of details even at a good distance..that's what CRTs had if you looked really carefully you could see the texture on the wall far at the end of a dark tunnel, with LCDs you see a small distance and then you have a black patch of nothingness. btw Z35 screen uniformity was great, low backlight bleed no cloduing great colors stock that's why I felt evenm more stabbed in the back when I realized VA technology was a failure and there was nothing to be done to save this, it shouldn't be sold at all or if yes for 1/3 of the price of what they are because it's a faulty technology. IPS/TN/OLED/PLASMA even the bad samples never had something that broken.

I still choose 4k over 2k 120 or 200hz if price not much difference

And Ill still choose a 2k 21:9 over a 16:9 4k. Its all preference. Give me a 21:9 1440p any day over a 5k 16:9. 30inch is a tad small for a curved 21:9. Needs to be 34inch for curved.
