All USB ports and screens connected to the Alienware Graphics Amplifier will work normally and the video card will be detected by the system, however, all graphics processing will continue to be performed by the discrete card in the notebook. Please read on for a workaround solution.

  1. Connect an external screen to the Alienware Graphics Amplifier

  2. Right Click on your windows desktop

  3. Click NVIDIA Control Panel

  4. Click Setup G-SYNC on the left side menu

  5. Uncheck the Enable G-SYNC checkbox

  10. Under Multiple Displays click on Make this my main display
