dell supports 1080p (aka 1920x1080)

but sometimes when u try and set the 1920x1080 through PC, you might get some mismatched refresh rate settings, hence the 'out of range' message...

i kena b4...but i can't remember wat i did to rectify it

but it really doesn't matter cuz y on earth would anyone wanna run 1920x1080 on the PC when they can have 1920x1200
