The display looks unstable and then freezes.
The screen may freeze when a resolution other than the recommended resolution is used or if the signal is not
stable. To resolve the issue, change the PC resolution to the recommended resolution.
The screen cannot be displayed in full screen.
A scaled SD (4:3) content file can cause black bars on both sides of an HD channel screen.
A video with an aspect ratio different from the product can cause black bars at the top and bottom of the screen.
Change the screen size setting to full screen on the product or source device.
Sound issue

If a source device is used
• Make sure the audio cable is properly connected to the audio input port on the product.
• Check the audio output settings for the source device.
(For example, if an HDMI cable is connected to the monitor, the audio setting for the cable box may need to be
changed to HDMI.)
If a DVI-HDMI cable is used, a separate audio cable is required.
If the product has a headphone port, make sure nothing is connected to it.
Reconnect the power cable to the device and then reboot the device.
There is static coming from the speakers.
Check the cable connection. Make sure a video cable is not connected to an audio input port.
Check the signal strength after connecting a cable.
Low signal level can cause corrupted sound.
