HDMI to DVI Monitor Input Lag

displaydvigaminghdmivga

I have a monitor (not an HDTV) that has two different types of input ports: VGA, and HDMI. No DVI. My GPU has two DVI ports and one HDMI port.

I use the computer primarily for gaming, although only on one monitor. If I were to convert the HDMI to DVI, would there be any real difference than if it were regular DVI? Alternatively, would I get better performance converting VGA to DVI instead?

There is no penalty to convert from DVI on your video card to HDMI on your monitor; The DVI ports on your graphics card simultaneously output a DVI-D, DVI-A, HDMI, and VGA signal over each DVI port. The DVI -> HDMI and DVI -> VGA "adapters" you find are really just selecting which signal to use.

Note, this is true only for the DVI ports you find on today's graphics cards as a video source. Judging from the fact that you mentioned a) A graphics card, and b) a monitor, I'm assuming this is your situation (and ignoring the fact that you said "convert the HDMI to DVI"). If you're talking about using things the other way around (where VGA or HDMI is the video source/output, and you have a DVI monitor/input), then the reverse does not hold true.
