Most 3D applications attempt to run on the primary display in full screen mode. This isn't necessarily the display labeled "1" from the Windows Control Panel. To check and make sure you have your 3D Ready display set as the primary display, follows these steps:
Change Primary Monitor
- Right click on the Windows Desktop and click Personalize > Display settings. On the Display Settings tab of the Display Properties dialog box, click the monitor icon that represents the monitor you want to designate as my main monitor.
- Click to select the Use this device as the main monitor check box. Note that this check box is unavailable when you select the monitor icon that is currently set as your primary monitor.
