Hello, excuse my english.
I have a problem with ATI and a BENQ G2750, a year ago i change my NVIDIA and buy ATI 7790, and that problem appears.
My monitor not got detected on boot, "No Signal" and when windows start windows/driver detect but i have a 640x480 resolution and can't change, i can only change using HDTV .
I upgrade one week ago to r9-290 and problem continue.
That seems a problem with that monitor only or DVI-D signal, becauseworks with VGA and HDMI (i not check with other DVI-D monitor)
nown with r9-290 i haven't VGA or analog signal i my problem its worst.
Anyone have idea?
