Hello. I have an MSI Geforce 4 MX 440 64 MB video card with TV-out. I was using Dualview with my Philips 150B Flat Monitor and TV (on Video-out) a time, but in these days, suddenly the DualView option dissapeared from the display mode list! What could be the problem? I tried to reinstall nVidia Forceware 81.98, but nothing happened.
