Hi there, I am using IBM Thinkpad R40 which has ATI MOBILITY RADEON as the display adapter. It ha built-in S-Video port. I turned off my TV (a Sony 47" HDTV) and the computer, then pluged in S-Video cable, and turned on TV and switched to the Channel where S-Video is connected, then I turned on the computer. The TV has a clone view of my desktop, but when I played movie, there is no video but a black rectangle on TV while I can view the video on the computer. I changed the Settings of Display Properties and chose "Extend my Windows desktop onto this monitor", and then I drag the video window to TV. Bingo - I can see the video now! So far so good... But after I finished viewing the movie, I inserted another disc. Oops, black window again! I repeated the procedure above again and again but it's always showing the black window on TV when I played video, and I could never make TV as a clone view of my desktop again like it was at the beginning. Remember I checked "Extend my Windows desktop onto this monitor", I unchecked this and hope it will go back to the clone view, but the TV just showed nothing instead of my desktop, and if I choose to extend my desktop to TV, it did extend the desktop, yet it couldn't show video. I don't know what has happened magically when I switched the movie ( I tried to play the fist movie, but it didn't work either). I really hope somebody could give me some hint. Thanks in advance - Frank

I suggest contacting ATI tech support. http://www.atitech.com/index.html

My problem has been resolved. The original OEM driver doesn't have the options to speicify the TV as the primary output, and after I installed the latest drvier from IBM's website, it gives me a lot of more options such as "Clone View", "Extend My Desktop to This Monitor", and Specifying which one to be the primary output,etc., while the only option available before is "Extend my Desktop to this Monitor". Thanks. -Frank
