Display resolution or color depth is incompatible

Symptoms
The following message appears:
“Display resolution or color depth is incompatible.”

Cause of problem
Invoke sessions require a minimum resolution of 1024x768 and color depth of 16 bit. The message appears because the display settings on your computer are incompatible with this requirement.

Solution
You need to change your display resolution. To do this, follow these steps:

In Windows XP:

  • Click on the Start button at the bottom left-hand corner of your screen and click on Control Panel.In the window that appears, double-click on the Display icon. In the window that opens, select the Settings tab.
  • Check the resolution at the left-hand side of the Settings tab. If your current setting is lower than 1024x768, move the slider to the right until it reaches 1024x768 or higher.
  • Check the color palette in the Color quality section on the right-hand side of the Settings tab in the Display Properties window. Choose High Color (16 bit) from the drop-down list.
  • in the Setting tab of the Display Properties window, click Apply:
    The settings change for 15 seconds. Click Yes if the change has applied properly. If you do not click on Yes, the settings will revert to the previous resolution and depth after 15 seconds.
    If you are unable to make any of the changes described above, unfortunately you will not be able to attend the Invoke session because of hardware incompatibility.
