Was initially worried about the PLS panel type as I've had experience with these panels not being up to scratch colour-wise before. This monitor however has no such issues. It's insanely bright (To the point where I've turned brightness down to 40/100) and the colour is immensely vibrant with very dark blacks.
Viewing angles are above par too, with the worst issue being a negligible desaturation when viewing from above (Pretty impractical anyway)
I'm not competitive FPS player or anything but for general gaming I can't notice any response issues.
The real winner for this monitor is purely the 1440p display. The extra screen real estate adds real value to the professional workspace and adds another level of sharpness to games.
Very happy with this AOC monitor. At this price, for this size and resolution, you just can't beat it. 5/5 from me.
