• A dialog box may appear on the screen to inform you of this change in
GPU. Click OK to confirm this change.

Always perform GPU switching under Windows operating system.
Notes:
•
The screen might go blank for a few seconds during GPU switch.

To gain the best quality of video output, switch to discrete GPU before
connecting an external display device through HDMI cable.

Some Direct3D applications running in full-screen mode might not be able to
detect the switch in GPU, resulting in a blank screen. Switch GPU before running
these applications.
