Honestly, for 2 months of trial I am delighted to have bought it for my setup Rtx5090 and i9 14900kf, the black impeccable with the hdr, the 400 hz too, and nothing else to say.

Perfect size for playing immersive games or watching films, deep blacks, very good contrast, I think it's the best 4K screen on the market, I recommend it.
