When selecting extended desktop without a 2nd screen attached clickshare says: "Cannot share extended desktop Check the Barco FAQ at"


To fix the problem, update your AMD catalyst drivers to 13.8 or higher

Extended desktop doesn't work on systems with:

  • Windows XP / Vista
  • Mac OS X
  • AMD Catalyst 13.1
  • AMD Catalyst 13.4

We have seen problems with:

  • nvidia control panel 320.18

To verify if your system should be able to share extended desktop:

  1. Please open you resolutions settings in Windows.
  2. Press windows + p keycombination
  3. Select extend mode
  4. Verify if you have now 2 visible screens in the resolution window or not
  5. if your system is not able to make the second screen and is not in the list above please contact us.
