Certain video files, which use video overlay, may not display properly on a secondary monitor when running in dual monitor mode. To enable video playback on your secondary monitor or TV, Full Screen Video should be enabled.
Please follow the directions below to enable Full Screen Video:
- Right-click on your Desktop and select "Properties."
- This will bring up the Display Properties control panel. Click on the "Settings" tab and then click on the advanced button.
- Click on the tab corresponding to the graphics card installed in your computer. For example, if you are using an NVIDIA based GeforceFX 5700 graphics card, choose the GeforceFX 5700 tab. A pull out window will appear to the left of the panel. Select "Full Screen Video" from the left pull out window.
- The "Full Screen Video" panel will appear. If you are running in Dualview mode, select "Auto-Select" from the "Full Screen Device" drop down menu . If you are running in Clone mode, choose "Secondary Display" from the "Full Screen Device" drop down menu option,
Click the OK button to confirm these changes. When a video, which uses video overlay, is running, the video will now appear in Full Screen mode on your secondary display.
