Consider the following scenario:
The operating system is Windows 8 and you are using multiple displays in "duplicate" mode. When selecting Advanced Settings in the Screen Resolution Control Panel and then selecting the List All Modes button on the Adapter tab of the monitor and display driver dialog box, the list of available modes is different than the list that is displayed on Windows 7.
This behavior is by design. The list of display modes available when "duplicate" mode is selected on a Windows 8 client is based upon the selected primary monitor at the time of selecting "duplicate" mode. In Windows 7, all display modes are displayed regardless of the primary monitor selection.
If the desired display mode is not available in "duplicate" mode, select a different monitor as the primary monitor prior to selecting "duplicate" display mode.
