When i plugged my computer into my tv using the hdmi input and i turn my computer on it goes through the loading screen then shows windows there. then after windows loads up it does a muli colored horizontal line then goes to black. i have a radeon 9500 video card with 128mb memory on the computer. I have gotten it to work with my other computer that has an nvidia card. any ideas?
Are you using a DVI to HDMI converter? Radeon cards older than x1*** series or roundabout didnt support hdcp on dvi which is required to run Hi-Def rez thru an HDMI cable on most TVs. A video card with hdmi prebuilt in or HDCP compliance listed on the box should be able to handle it. And you should find a resolution both your normal monitor and HDTV can handle to set the coimputer to before you switch it over to the HDTV to be sure it will still show you picture. If you arent using 1080P you might as well use a component input which doesnt require HDCP.
