New monitor decision

[MatsyLR]

Hey, currently using two monitors one 27 and one 24.
Looking it upgrade to something bigger than 27 for my main monitor, maybe 30inch.
Need some choices on bigger monitors (maybe 1440p) with good black levels and colors, response time is a non factor as I'm not effected by it.
Price is a concern, but I'm open to anything below £400.

If you didn't need the colors I'd say at £420 a 4k monitor would be worth a try, or if you really need to stay under £400 get a B grade AOC 4k for £350. Plenty of decent 1440p monitors out now for under £300, take your pick on any of them.
