Edit: I'm a big fan of the Cooler Master GP27Q and GP27U. They both have eye-bleedingly gorgeous HDR and won't break the bank. You can get the Q for about $550 and the U for under $900; the difference is that the Q is 1440p and the U is 4K.

The only criticism I have at all with them is that the firmware is kinda fucky (you will be spending your first few days with it constantly messing with settings, I guarantee) and doing computer stuff can be aggravating with FALD active; for example, I can scroll through a reddit post and watch the background color change between white and various shades of gray as I scroll, depending on the density of the text. But this is a complete non-issue if you're buying it as a TV replacement, and even if you are using it as a regular computer monitor, you get used to it real fast (and you can always turn off FALD when you're not watching something).
