Running a gigabyte mobo with hdmi out to a Hitachi rptv about 5 years old, model 57uwx20b, video card is hd 3200. I'm running hdmi to the dvi port on the tv. I get a clear picture with xbmc, but it is washed out, very dull color, I've tried every setting in ati control panel with no luck. could this be a bad hdmi cable? or should i just run straight dvi? When I hook it up to my 24 inch dell the picture is wonderful. I know I need a new tv, but any help appreciated.
