IPS is best for photo editing ..... 120/144Hz TN is best for gaming.
All models are LED.
MS doesnt matter if ya looking at advertised as they all lie
.... well the lower prices ones all do. Read reputable sites like tftcentral for 'real numbers'.
My son has a Dell IPS which he bought for photo editing while minoring in photography in college.... he'll play games on it, but when the other puter is free with the 120Hz TN panel, he'll play on that one.
