Err, no it does not mean more performance.Quote from okb1100
I am an IT student and our teacher told "DVI port doesn't use the analog-digital converter on GPU so that means more performance" if that's right,i may buy a DVI monitor
There is no difference between HDMI and DVI. There is no difference between VGA, DVI, HDMI, and DP outside of their max supported resolutions, that VGA is analog, and that there is more interference with VGA.
There is no "performance" or "color" difference.
