Hello there. Not really sure how to describe my problem.

Recently my monitor decided to start dieing on me (an Philips 190cw8fb), so I purchased an LG LED 22en33.
Was quite happy to get a bigger monitor but I think it's broken or something.

My new monitor has way worse, irregular image comparing to the old one, top corners seem to have a too high contrast, middle is fine and the bottom seems pale and grayed out a lot, similar to a gradient effect put over the whole screen.
To see the image relatively okay, I would have to stay over 2m away from it and lay on the ground, that doesn't seem normal, lol.
Autotuning sometimes makes the image wavy and ripped, especialy when I auto adjust on full text.

I know LCD TN monitors aren't good but I don't think it's normal for a new LED monitor to be so bad comparing to a very old LCD model.

What should I do, is it enought for a check at the store and maybe a payback/getting a replacement?
