High quality, high resolution monitor advice


I’m looking for a high quality, high resolution monitor with good colours; preferably IPS, but I’m unsure of what to go for. I’m not particularly looking to game on it, so it doesn’t necessarily have to have a high refresh rate but it would be a bonus. I have been looking at some Korean monitors but there aren’t many solid reviews on them. My price range would be around the ~£450 range.

Any advice would be appreciated.
