Has anyone had any luck connecting their 28LD5200 up to their pc using the dvi input? For some reason, I can only get the tele to sync to the signal if I disable my graphics card and default to the standard windows drivers? Apparently this problem doesn't manifest itself with the analouge input but I'm loathed to follow this option because my graphics card doesn't have an analogue out. I've gone through all the resolutions the manual says are supported on the dvi in but no luck. Anyone been succesful in attempting this?
