After tons of research i could not find a good monitor that has a high quality with IPS panel and no BLeeding or noticable Input lag under 400 $!
I think of Asus PA248Q , but somebody said this has a noticable input lag and bleeding ,
I thought about Benq XL2420 but it doesn't have a ips panel !
I wanted to buy 27" and 120 hz but 27 inch is good with 1440 P resoulation and i would have pixel density ,isn't it?!
After that 120 hz is good for gamers who paly above 120 FPS and not for 80 FPS even though , my videocar can not handle 120 FPS ! ( I have a GTX 570). I think a 24 inch with IPS panel and low respons time/ input lag is Fair decision . I dont like to buy online monitor!
