If your PC supports Intel® WiDi and it supports connections over the Intel® WiDi 3.5 version, you can start the Screen Share app on your ENERGY STAR® Qualified LG 43" Class (42.5" Diagonal) 4K UHD Smart LED TV w/ webOS 2.0, Model # 43UF6400 then start Intel® WiDi on the device you want to connect. Your TV will be displayed in the list of available devices and you can select your TV to request a connection, and a message asking you to enter an 8-digit PIN will appear on the TV screen. Enter the PIN and select Connect. After the connection is established, the TV will display the screen of the connected device. Intel® WiDi allows connections without a wireless router. For the best possible performance, connect your device to a 5 GHz router...^IFV
