When I try to change the PC resolution, a message “Mode
Not Supported" appears.

There is no sound from the speakers in HDMI mode when a
DVI-HDMI cable is connected.
DVI cables do not transmit sound data.
Make sure to connect the audio cable to the correct input port to enable audio.
HDMI Black Level is not functioning properly on an external
device with HDMI YCbCr output.
This function is available only when a source device with RGB signal, such as a DVD player and
STB, is connected to the product to HDMI cable.
There is not sound in HDMI mode
The picture may not display normally (if at all) or the audio may not work if an external device
that uses an older version of HDMI mode is connected to the product.
If these issues occur, connect an audio cable along with the HDMI cable.
Some PC graphics cards may not automatically recognize HDMI signals that do not include
sound. In this case, manually select a sound input.
