Measurements were made by numerous websites many years ago when the digital connections first came out, including AnandTech, and it was found to be minor (e.g. 1ms or 2ms).flood wrote:Are there actual measurements of this? or is it something related to the HDMI/DVI/DisplayPort protocols?Chief Blur Buster wrote:VGA is the lowest lag, while HDMI/DVI/DisplayPort has a bit more.
I suppose it varies depending on the graphics card and monitor...
Is Bodnar input lag tester accurate?

Re: Is Bodnar input lag tester accurate?
it would be interesting to try that again on modern hardware.

This makes sense but there could be some overhead inherent in DVI. Regardless it's not a big deal and I avoid vga on lcd screens simply to not have to adjust phase.In addition, using the VGA input on any LCD is bound to add additional lag, as this is definitely a hardware scaler operation to go from analog to digital signaling, compared to the entirely digital DVI datapath.
