I have a Philips 23pf9946 lcd tv which works beautifully when connected to my GeForce FX5200 card via analogue VGA. However, whenever i try using the DVI connection, the TV displays "no input signal". Does anyone know what is causing the problem? By way of further information, i don't know if it's relevant. The graphics card has a DVI-I output, and the TV has a DVI-D input. The cable i have is a single pass DVI-D. Everything I have read so far, indicates that the cable should be suitable. Yet it does not work. Any ideas? Thanks.
