That's the game itself, it's extremely low quality.

Some game developers don't create their games under calibration. While most of the big ones do.
Couldn't be happier with this monitor now I'm finished with all the returns lol. Can't spot any bleed at all on my normal brightness settings and just enjoying gaming and studio work on it .
Colours are just outstanding. Especially when calibrated but even when not it still looked good. Il never go back to 16:9 for gaming as this just takes it up a level.. Even more than 4k in my opinion. It's an expensive monitor but when you think about how much 4k ips panels cost for a 34 inch the price isn't that terrible for what you get.
Mine shipped today - should have it early next week @ work - cheapskate isnt sending it via tracked service though
My LG calibrator was just dispatched, can't believe it actually went through at £5.18!
£5 for a pretty much professional calibration is crazy lol.
