Speaking of advantages, while IPS panels have improved in the three key areas listed above, those improvements did not come at the cost of existing qualities.
With an IPS gaming monitor you get the best colours hands down. Regardless of colour space, an IPS panel gets you closest to the original intent of the artists than any other panel type. In other words, you get the most accurate colour depiction with IPS. If you want to enjoy your games in the liveliest colour possible, choose IPS.
Viewing angles! That’s another area where IPS stands head and shoulders above all competitors. With 178/178 degrees on the vertical and horizontal axes, IPS gaming monitors consistently retain brightness levels even from extremely low angles. You could be standing five meters off to the side of your IPS monitor eating an apple on a break from a gaming session and still not notice much difference in image quality, whereby with a TN or even VA most of the picture would be reduced to mush. That makes IPS gaming monitors great for flexibility in where you place yourself while gaming and for local coop if you have several people gaming on one screen or at the very least looking on when you game. IPS is thus the most sociable LCD technology.
In summation, IPS gaming monitors aren’t just viable, they’re now advisable. The technology has outgrown past limitations and currently offers its advantages of great colours and viewing angles with no strings attached, unless you count the HDMI or DisplayPort cable.
