2560x1440 on 1920x1080 display works!!??

It works in a way your graphics card is sending 2560x1440 resolution to your monitor, but not in a way your monitor can display it. Read this:
http://en.wikipedia.org/wiki/Native_resolution

so what is it actually displaying then? it is definitely sharper and switched to 16:10 now, everything is smaller, the games look clearer, it looks alot like 2560x1440.

It's just optical illusion. It still displays 1920x1080 as it CANNOT display anything other than that physically. If you took a photo of your screen at both resolutions and zoom it in, you'll see the pixels are the exact same size.

P. S. 2560x1440 is 16:9. It's 16:10 equivalent is 2560x1600.

yeah, i figured it couldnt do more than it is capable of lol... , so why would it resize everything smaller then?? and i still dont get how it looks better lol. and it definitely does. and its made my framerate slower.

p.s i was asking about graphics cards last night lol and you helped me out there, jus thought i would update you that i have decided to scrap the 7870 idea and go with nvidia again and get a 670.

i see, makes sense. might have to invest in a 2560x 1440 monitor if pretend 2560x 1440 looks so good to me lol! switched back now as it all must have been a placebo effect, obviously by what your saying, the graphics card was just working harder, for no gain, except everything was tiny lol. thanks.
