Using Display Port Question

[rossiboy001]

Hi, Just wondering if using a GPU outputting DVi and display port signals to run triple screen surround has any performance loss against running 3x display port? I was just thinking that the GPU has to create two signals of different protocols and this splitting between two jobs may make some sort of hit in lag and or FPS? Its not a question of is DVI or DP better what there outputs are ect, its a specific GPU related question about its output. I know when using DVI and HDMI is the same signal so that combination i would expect not too. Of course this is easily solved with a third DP lead but is it worth the bother?

I've run 3 screens from DVI-DVI-DP and DVI-DVI-HDMI from the same GPUs at different times and noticed no difference in performance at all. The GPU has to produce an independent output to each screen anyway so I can't believe there would even be a theoretical benefit (workload-wise) to having matching output connectors for different screens. There certainly wouldn't be a measurable one.

So long as the connectors you're using work to get a digital signal from your GPU(s) to your monitor(s), I really wouldn't worry any more than that. The only connection type I try to avoid is VGA, but that's just because I think it should have died off a long time ago!

Thanks confused stu, so just carry on with what i got. The only need I think then for 3 matching will be for 3D surround should I look at that one day.
