What should I do if I do not see proper images or videos?
❑ Be sure to select Highest (32 bit) for the display colors before using video/image software or starting DVD playback.
Selecting any other option may prevent such software from displaying images successfully. To change the display colors,
follow these steps:
1
Right-click on the desktop and select Personalize.
2
Click Display Settings.
3
Select Highest (32 bit) under Colors.
❑ Do not change the display resolution or colors while using video/image software or playing DVDs, as it may cause
unsuccessful playback/display or unstable system operations.
Additionally, it is recommended you disable your screen saver before starting DVD playback. If the screen saver is
enabled, it may be activated during DVD playback and prevent it from running successfully. Some screen savers have
been found to even change the display resolution and colors.
What should I do if no image is displayed on my TV screen or external display connected
to the HDMI output port?
❑ The HDMI output port is disabled when your computer is in STAMINA mode. Change the performance mode to SPEED
mode before connecting an external device to the HDMI output port. See Selecting Performance Modes
for
mode selection.
❑ Make sure you are using an HDCP-compliant display. The copyright protected contents are not displayed on a non-HDCP
compliant display. See Connecting a Computer Display
for more information.
