Hi, which application do you use to watch video's from websites? If you use mediacenter, please check http://windows.microsoft.com/en-us/windows7/How-do-I-change-the-way-Windows-Media-Center-looks-on-my-display For media Player check Open Media Player -> Right click -> More Options -> Devices -> Display -> Properties and adjust the aspect ratio. For other softwares you should check your helpfile/manual for "how to change aspect ratio".MCP/MCSA/MCTS/MCITP
