a monitor with an HDMI cable, but the screen display or sound does not work correctly. Disconnect and then reconnect the HDMI cable to reset the connection. Disconnect the HDMI cable from the computer and television. Compare the HDMI connector to the HDMI port. The connector on the cable must match the port. Connect the HDMI cable to the ports on the computer and television. Set the input source on the television to
match the port the HDMI cable is connected to, and then check the display and sound again. If the display or sound still does not work
correctly, continue to the next step. On your computer, configure the sound settings for the HDMI sound output. Select Start, type Sound Settings, and then select it from the results. Select Sound Control Panel. Select the connected monitor, and then select Set Default. Select Properties, and then select the Levels tab. Set the monitor volume to at least seventy-five, and then select OK. If changing the sound settings and volume do not resolve the problem, continue to the next step.
