can a dvi splitter operate both ways e.g. instead of turning one output into two can you use it to connect two dvi connections to one like two computers into one monitor.

if not can i connect a pc to the other end of the "Y" splitter and the other end to a monitor basically what i asked just above minus the second computer?

 

the thing is i have a dvi connection leading from my wii component cable + adapter but its DVI-I and the dvi input for my monitor doesn't support that :\ it only supports dvi-D and similar connections but my dvi Y cable has a dvi D on one end and a DVI_I on the other so could i use that like a normal dvi canle ?

 

I'm assuming as you are saying your monitor only supports DVI-D it really only supports DVI-D. DVI-I is an analog + digital cable type whereas D is only digital. Now assuming your Wii is using the DVI-I with only the analog signal (can't imagine that being digital as it is component which is an analog signal, there would have to be a converter inside the cable somewhere otherwise) you simply cannot hook it up to your monitor without a component converter to either DVI-D or another format your monitor understands (VGA maybe).

Aside from that, combining 2 outputs on 1 line is a bad idea. Think about it, if it is an analoge signal and one source says 5 and the other 3, what will be the outcome (aside from possibly dead hardware on both ends)? Same for digital, what happens if different or even the same signals get sent for that matter.
