Ive been gaming on 2560 x 1600 displays for 3 yrs now but aren't affordable for most people at $1200+. If they added LED and 120hz the price would be over $1500 easy so its not cost efficient or that profitable for companies to invest in tech although I wish they would. The money is with those cheap 1080p displays for around $250 people tend to eat up. I'm going to make the jump to a 4K display next year when they come down to Earth prices for around a grand. Maybe those will be LED and 120hz or better.
