SYMPTOMS
When you hot or warm dock a laptop computer into a docking station, the screen resolution or the frame rate may not change to the settings that you previously selected. For example, if you set up the laptop to have a 800x600 resolution when it is undocked and 1024x768 when it is docked, the resolution remains at 800x600 when you hot dock the laptop in a docking station. If you undock the laptop, the resolution may change to the docked setting, 1024x768 in this example.

Additionally, if you start the laptop in the docking station, then undock the laptop, the display resolution may not change. For example, using the same settings listed earlier, the laptop starts into Windows at 1024x768 and will not change when the laptop is undocked.



CAUSE
This problem occurs because the information that is stored in the hardware profile is not processed during a hot or a warm docking/undocking procedure.



RESOLUTION
To effectively switch video modes, use one of the following methods:
 * Use the Fn + (function key) combination to toggle the display between the internal laptop computer screen and external monitor. The function key for this use varies, depending on the manufacturer of the laptop computer.
 * Use the Display Properties tool in Control Panel to set the screen resolution or the frame rate.
 * Restart the computer.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
