Overlays need additional onboard graphics memory and may not be available under
all resolutions. You may want to reduce the resolution or color depth if you have
problems accessing overlay functionality.
Using Video Overlay Settings
Use the Video Overlay settings to adjust the quality of video or DVD playback on
your display.
Note that these settings affect videos that are created using the hardware overlay, but
have no effect on videos created using software overlays, or a “blit” process such as
VMR.
Note:

Tip:
Overlays need additional onboard graphics memory and may not be
available under all resolutions. You may want to reduce the resolution
or color depth if you have problems accessing overlay functionality.
Tip:
If the stereo or overlay features do not work properly, you may want to
try setting different screen resolutions and refresh rates until you arrive
at a setting or combination of settings for better results.
