I have two HDMI inputs on my TV. One say's (DVI) next to it. When I plug my laptop into one of them the screen on the laptop seems to go to 4:3 and the picture the TV screen seems to be cut off or stretched out. If i use the other input it works fine. I haven't noticed if it makes a difference with my PS3 or not.
So whats the difference between the two inputs and why does it do that to the screen? Should I just use one for both my PS3 and my laptop?
the one labeled dvi is for computer use and might have different settings. honestly though what input you use on the tv normally doesnt matter however on a few particular models it is.
if the picture looks zoomed in or zoomed out its likely your overscan/underscan settings in windows. if it looks to be a different resolution than what the monitor is (ie looks 4:3 with black bars when your tv is 16:9) then it might be your laptop display mode (mirror display instead of extend) or perhaps your system having the wrong resolution set for the external monitor (tv)
i have a laptop which i've hooked to many tvs and typically overscan/underscan issues are the only problem i've had and those are normally pretty easy to resolve.
