[LG TV No Signal] I have connected a PC to the TV, but the No Signal message appears.

Troubleshooting

To display the same content on both your TV and PC screens, you need to choose the [Duplicate] option in the Multiple Displays mode.
In the PC's display settings, you can choose from multiple display modes, including [PC screen only], [Duplicate], [Expand], and [Second screen only].

Causes and Symptoms

  • Multiple Displays mode is set to [PC screen only].
  • This issue may be caused by a problem with the graphics card driver installed on the computer.

Wait! Here are more tips!
If your PC does not have an HDMI port but only has a DVI port, then use a DVI-to-HDMI gender to connect the PC and TV with a DVI cable.
When using a DVI cable, a separate audio cable must be connected as well to connect the audio.
Use a 3.5 mm stereo cable: One end to the [Audio Out] port on the back of the TV and the other to the [Audio Out] port on your PC.

※ Supported ports may differ depending on the product being used.
Please refer to the user manual for your particular model.
