So I just bought an Evga GTX 970 FTW from newegg. Got the card yesterday and installed it. Only problem is that it wont send a video signal to my Qnix Qx2710 monitor? The monitor's blue light comes on and doesn't blink, and windows recognizes that it is connected, but the screen just stays black. I've tried a few different dvi-d cables and can't get it to work. All the other ports seem to work fine, is it possible to just have a broken dvi port on a graphics card? Thanks.

Are you using a DVI cable or a DVI-D cable? The 1440p monitors need DVI-D to run at full resolution, but not sure that is the problem. Can you connect another monitor to that card via DVI-D? Also can you try running an HDMI connection? Not sure that monitor supports 1440p over HDMI, but you should at least get it to run at 1080p just to make sure the monitor is not completely dead.

FYI I went through two of the Korean knock-offs and gave up after getting two bad ones. It's possible it could be a bad DVI port on the monitor, or the monitor is just DOA. This is why you should check the video card with another monitor if you can and try a different connection (HDMI) to the Qnix.

Sorry I should have made it more clear, the monitor was working fine with my old graphics card a week ago, and I wanted to test it with a different graphics card but I sold the old one so I can't. And yeah Im using a dual link dvi-d cable. I can't test it with hdmi because my qnix only has a dual link dvi port.

Yeah its a Corsair TX650w. Was more than enough for my R9 290. I'm currently using the 970 on my tv with the hdmi port and the card works fine.

Can someone besides this idiot help me? It's giving me flashbacks to when I had to argue with Dell's Indian customer service.

It appears some Qx2710's have both DVI-D and HDMI inputs and others do not. Now that we got that cleared up, we know the monitor worked with the old GPU, so that's not the issue. You tried different DVI-D cables and that didn't work either. You have the GPU connected via HDMI to your HDTV and it works fine, so the card is not DOA.

The only other thing I can think of trying is seeing if you can get hold of a DVI-VGA adapter and see if you can connect the DVI-out from the GPU to a VGA-in into the TV. Just about all the GPUs I've bought over the years came with a DVI-VGA adapter. Also that GPU is like my 970s in that they have two DVI outputs, a DVI-I and DVI-D. The DVI-VGA adapter goes into the DVI-I output (bottom one).
