Ive been fooling around with this notion but for the life of me I cant seem to get it to work. Ive got a Radeon x600 Connected to a DVI to HDMI cable which is connected to the HDMi port on my Sony KSL32M4000. Now in safe mode I can use it just fine with no problems. Also before I install the drivers no problems. As soon as I install I get invalid format from the TV. I can see the splash screen for the bios and then Xp. but after that Invalid format. Is my computer pushing a higher resolution to the TV thru the HDMI?
