How to Cast Windows PC to LG TV to Extend Displays (Wireless Display Mirror)

To connect your PC to an LG TV and extend displays, follow these steps:

1. Check Available Ports
PC Ports: Identify the video output ports on your PC (e.g., HDMI, DisplayPort, VGA, or USB-C).

LG TV Ports: Check the input ports on your LG TV (most modern LG TVs have HDMI, some older models may have VGA or DVI).
Ensure you have a compatible cable (e.g., HDMI-to-HDMI, DisplayPort-to-HDMI) or adapter.

2. Connect the PC to the LG TV
HDMI (Most Common):
Plug one end of an HDMI cable into your PC’s HDMI output port.
Plug the other end into an HDMI input port on your LG TV.
Other Connections:

For DisplayPort or USB-C, use an appropriate adapter or cable (e.g., DisplayPort-to-HDMI or USB-C-to-HDMI).
For VGA, connect a VGA cable and ensure your TV supports VGA input (less common on newer LG TVs).

Power on both the PC and LG TV.

3. Select the Input Source on the LG TV
Press the Input or Source button on your LG TV remote.
Select the corresponding input (e.g., HDMI 1, HDMI 2) where your PC is connected.

4. Configure Display Settings on Your PC
Windows:

Right-click on the desktop and select Display Settings.
Scroll to Multiple Displays and choose Extend these displays to use the LG TV as an additional screen.

Click Detect to ensure the TV is recognized.
Adjust the resolution (e.g., 1920x1080 or 4K if supported) and orientation for the TV.

Drag the display boxes in the settings to align with your physical setup (e.g., TV to the right of the PC monitor).
