I have a custom built computer with a geforce fx 5200 and i jus upgraded the driver with a newer driver from the nVidia website:: 163.75_forceware_winxp_32bit_english_whql.I've hooked my desktop to the tv and i opened up the display settings and nVidia control panel but i still can't get it to work. i even tried to force the software to detect my tv by using the rigorous deisplay detectin and still nothing. any ideas?
