Any monitor expert here?

I'm planning on upgrading my monitor to either a 1440p or 4K monitor preferably ips QHD for my secondary screen. Size around 24-27 inches since I don't have the desk space for my other 2 monitors so no 32 inches. 144+hz is a bonus for gaming but it's not important since I do have a gaming monitor. Colour accuracy is appreciated for my work as well so if there's an adobe rgb certified that's a bonus but not needed since my budget is only around $350-550. Currently, I'm interested in Samsung G5 but I need more references before buying it. I also don't understand that that WQHD vs QHD so I don't know which one is better. I would appreciate it if you help.

Xiaomi g pro 27 <- this one is a bit pricy, but really good.
Lenovo r27qe
Skyworth H27G30Q <- the cheapest of the bunch.
only xiaomi one got the actual HDR feature. other than LED monitor, HDR in LCD monitor doesn't feel good.

Samsung G5 has decent colours but nothing crazy, there are definitely much better colour quality monitors out there.

If you are going for sqrt(2)K aim for atleast 27 inch display. I bought an BENQ 4K monitor for around 600USD @27 inches but I suffered from the same issue of desk space.
Now I kinda regret it cause I cannot really enjoy 4K on 27 inches. You need 32 inch or higher to truly appreciate a 4K monitor.

Also the jump from 1080p to sqrt(2)K is massive. However sqrt(2)K to 4K is not that massive at least on 27 inches. Definately don't buy a 24 inch monitor for anything above 1080p.

If you already have a high refresh rate monitor, probably get a 2K BENQ monitor with good colour quality and HDR (it matters) at 60FPS. Use it for AAA gaming as you probably are anyways not getting crazy FPS with maxed settings. It will also act as a good monitor for watching movies/youtube.

Only for valorant or other eSports, pull out your gaming monitor.
