kenzobusceti Posted May 15, 2015 Share Posted May 15, 2015 Hi there Today I bought a new 27" display from Dell, the u2715h. Since my system is running with a gt8800 and I just have a dvi dual output I had to connect a hdmi adapter to a dvi d cable to connect this display. However, everything fine running this display at 2048 x 1152 @ 60 Hz but when I try to get full resolution to 2560 x 1440 @ 60 Hz I just get a black screen, the display tells me that it needs proper input, can't handle the signal. Any idea what I could try to fix this problem? Thx Link to comment Share on other sites More sharing options...

Thx You need Display Port or at least HDMI all the way at them resolutions you can get a dual link DVI cable I think that is what they call them that allows that high a resolution (up to 2560x1600 IIRC) over it. Realistically you are probably looking at newer video card to drive that display at that resolution as the specs I looked up list no DVI input.
