Things to know before connecting your PC to your TV
1. Different connection methods
There are two ways to share your screen: a wired connection using an HDMI cable, or a wireless connection using Wi-Fi. Choose the method that works best for your setup.
2. Different wireless standards by operating system
Windows PCs and Macs use different methods to share the screen wirelessly. Make sure to use the correct settings for your operating system.
3. Different cable specifications affecting audio and video
Depending on the type or manufacturer of your cable, audio or video signals may not transmit properly.
How to connect your PC to your TV
Case 1. Connect with an HDMI cable
Connect an HDMI cable to the HDMI ports on the back of your PC and TV.

f the TV screen is blank, press the [Windows] key and [P] at the same time on your keyboard to choose a display option ([Duplicate], [Extend], etc.).
For a Mac, follow the on-screen instructions to select a sharing option. To skip this step the next time you connect, select [Set as default] on the screen.

FAQ
- Q. Why is my mouse lagging or stuttering after connecting wirelessly?
- A. Nearby Wi-Fi signals may be causing interference. For a smoother connection, set your router to the 5 GHz band and place your router, PC, and TV as close to each other as possible.
- Q. Why is the sound playing only from my PC, not the TV, after connecting with an HDMI cable?
- A. This may be caused by your PC sound settings or using a video-only cable. Make sure you are using a standard HDMI cable. Then, select the speaker icon in the bottom-right corner of the taskbar and change the playback device to [LG TV].
