connected.
• Turn the TV off and back on using the remote control.
• Restart the PC with the TV on.
• Check if the resolution is correctly set for PC input.
• To use the TV as a secondary monitor, check if the
connected desktop or laptop supports dual monitor
displays.

There is no sound after
connecting the computer
with the HDMI cable.

supports HDMI voice output. (Video cards manufactured in
DVI format require connection of a separate sound cable.)
