Why don't you use a splitter for the video signal?

> Hi everyone,
> 
> I would like to connect 2 LCD computer screens (monitors) to one PC by 2
> cables each with a length of 5 meters. Most of graphic cards provide one
> D-Sub, one DVI and one HDMI port. In my experiment I have to present the
> same stimulus in the same time on each screen. My question is: will there
> be any time difference in transfering the image by cable connected to D-
> sub and DVI slot? The first one is analog port and DVI/HDMI are digital.
> In my view, I should use DVI and HDMI to provide the same latency on each
> screen (I am not sure that these 2 different ports and cables provides the
> same transfer speed). The problem is, I do not have monitor with HDMI
> port. If I use adapter HDMI-->DVI will it not change the time of
> transfering the data?

> Thank you in advance for all replies!
