各位大大，我詢問了美國"MagicTune"的客服，他們今天給了這個失望的答案！

Thank you for the inquiry. We have discovered that the NVIDIA GeForce 6600
series of graphic cards only support MagicTune when connected with the VGA
cable. DVI connections will not allow the DDC/CI communication needed by the
MagicTune software. Our engineering team is currently looking into this
issue.

Please use the VGA connection of your monitor if you wish to use MagicTune
at this time.

We apologize for this inconvenience.

Regards,
Technical Support Team
