[LG Monitor] I connected a TV monitor to the PC, but there is something wrong on the screen.

Troubleshooting Monitor Products 07/17/2023

You connected your TV monitor to the PC, but is the screen blurry or out of position?

A TV monitor has built-in antenna connection ports and speakers, thus you can watch TV and connect it to the PC for use as a monitor.
When connecting it to the PC for use, if the monitor or PC setting is wrong, then the screen can get blurry or size fails to fit the monitor.
In this case, check the HDMI device connection setting and the resolution of the PC.

Causes and Symptoms

  • When connecting the HDMI cable to it, the monitor input setting is wrong.
  • The resolution of PC is set incorrectly for the monitor screen.
