GTX 780, how do I get 144hz out of HDMI or DP?
I have dual GTX 780s and will be soon upgrading to quad GTX 780s in a 4 way sli configuration. For a while I was running 2 monitors, but as a look developer, screen space, colors, frame rates, and signal frequency are very important to an almost religious level so I bought 3 new monitors running at 144hz with a true color calibrator and sRGB config.
Problem...... Each 780 only has 2 DVI ports so I am plugging my third monitor into the second card, but that prohibits me from running sli in max performance mode. When I try using HDMI or Display Port cables to connect them all to the first card, I no longer can set the frequency to 144hz. In fact, it caps me at 60hz. I have considered trying to overclock the monitor but I feel its cable related. My HDMI and DP cables are not suited (as far as I am aware) for 4k or high frame rates. After doing some research, some people have said the cable is rather irreverent, but where I looked, that problem was never solved.
I hope someone might be able to help me figure out a way to solve this, could an active display port adapter to DVI-D perhaps fix this? is there an easier way? is it just the cables? I hope someone can help because I really want to free up this second, and soon third and fourth graphics cards so I can continue working without my render engines crashing every 5 seconds.
(side note, my HDMI and DP cables are about 6 years old, could that be part of the problem?)
