I have a 2006 13" MacBook. I am trying to run a bicycle training program (Bootcamp-Windows XP) through a 2003 Toshiba standard TV. I have all the correct adapters and cables and have set them up correctly. What I get on the TV screen is an image that is almost there, but appears as though it needs the tuning tweaked a little (however, I cannot tune this TV). Image is attached. When running the PC-based program, the program assessed my computer's specs as being OK to run the program although there is no video or sound card. Could the video card be the issue? Any other ideas? Thanks.
