Kaya Mehmet I have this 144hz samsung curved monitor it is AMAZING. I would urge you to look at the new chg70 27inch as its 2k 1440p and HDR.
If looking for a 1080P 144hz display this Samsung one is fantastic.
My wife has a 144hz 27" 1080P Gsync Acer Predator with the eye tracking tech. This samsung blows it out of the water in color fedlity and overall picture quality.
I would eagerly sell you mine if your in the US so i could upgrade to the chg70. IF money permits check out the chg70.
