Well, I posted another advice topic before, but i've got more budget so I'll try to go for the next tier.
I'm going to wait until Black Friday, knowing that right now only the PG35VQ is available in Spain, and it cost about 3000USD, the monitors that i'm looking for are:
-Acer Predator x35/Asus PG35VQ/AOC AG353UCG (For what i've heard it's the same as the other 2 and it will cost significantly less around the price of the LG, but i'm not sure)
-LG 38GL950G
If the AOC thing is correct, then we're at the same price range, the LG with 3840x1600 and a 38" display and the others with true HDR (FALD, HDR1000, and all that sort of stuff) but 3440x1440 and 34".
The big point right here is if the HDR is that different in games that support it, I would try it, but i don't have the opportunity to do so due to where I live.
