DisplayPort give less input lag ?

Using DisplayPort to conneting the monitor i'll have less input lag ?
post #2 of 5
Latency and band with are two different things. Input lag is caused by high latency. Moving to Display will only increase your band with not decrease the latency between the input to display.

It is possible, but depends on implementation. As a general statement this should not be true, though. For displays with multiple input options all incoming signals usually pass the control electronics of the display before being passed on into the TCon of the screen. For display-port to be "faster" the implementation would need to be such that display-port input is passed through directly to TCon of the display while for any other input the input is first converted into eDP and then sent into the TCon of the screen. But for all practical purposes I would say there is no perceivable difference in latency in regards of what kind of input you are using.

i see an user review where dell u2713hm with display port reduce its input lag to almost zero.

And prad.de misured all low value of input lag using DP as connection

Then it is quite possible that in the case of U2713HM there is indeed a difference. It is relatively modern screen so it's possible that they have eDP panel and indeed just pass DP port straight to panel while having conversion circuitry in the path of other signal types. It is ofc only speculation from my side as I have no experience with that particular screen nor I am aware of how it's engineered internally.
