I have a pavillion dv9850ea lappy the graphics chip installed is artifacting and blanking my screen when any nvidia driver is installed, i know there is a problem with the graphics chip itself ,but when i operate with the basic vista driver all is ok.I don't game with this but i do watch a lot of hd tv/movies through the HDMI port connected to my lcd,my question, is there another basic driver i could try to enable me to watch hd content that is not by Nvidia....(drivers tried - all of the HP ones and THE ones from Nvidia download section)
