Hi i have a AOC E2795VH 27" widescreen LED monitor and a cheap 19" generic monitor, i run extended desktop. Switched computer on this morning and the AOC displays no signal, i have tried both DVI and HDMI and still no joy the other monitor is still working fine, so i have pluged the AOC into my PS3 and still no signal so im thinking the monitor is at fault anyone had a similar problem? should i RMA i got it in November last year.
