Media Playback
-
During video playback on all platforms, please do not change the display mode, position or
arrangement of video player window (such as dragging the video player window between
main display and attached display). This usually causes the video player to have strange
behavior and the video may stop playing. We suggest stopping the video playback, moving the
window to the USB graphics device attached display and then selecting the video clip to start
playing.
-
You may experience poor video performance on USB graphics device attached display under
some low-spec PC system.
-
Video rendering using hardware overlays is supported.
-
Some DVD playback software packages do not support playing on a second display adapter of
any kind. You may try to open the media player in the secondary display first before start
playing the DVD.
