Alienware 38 Curved Gaming Monitor - AW3821DW

Anyone have it? How is the HDR, how are the colors? Does the G-Sync work well in MSFS? What’s the lowest refresh rate that it supports with G-Sync? Just got a good deal on a RTX 3090 and am looking to upgrade my monitor as well. Currently have a 21:9, but it’s 34" and this one is 38". Have had this monitor for about 5 years now.

I saw this post, but am not too concerned. But this is why I’m asking.

I saw the Asus Rog Swift, but dunno if I want to spend that much money for the customization.
