I doubt the video card's drivers accept S-Video as a connected monitor, therefore I doubt they'll let you use it as one. IMHO it's best not to use the TV as any part of the Windows desk top. I would save the tricks for a genuine dual monitor rig.why doesnt it load the windows xp screen on the tv, rather it loads it on the laptop. wit the dvi cable it would load the xp windows screen on both, but this one doesnt. how can i fix that?
