3.Connect devices: Plug one end of the HDMI cable into the HDMI output port of the computer, and the other end into the HDMI input port of the display device.
4.Switch signal source: Turn on the display device and use the remote control or panel buttons to switch the signal source to the corresponding HDMI input channel (such as HDMI 1, HDMI 2).
5.Set computer display mode: Press on your computerWin+P(Windows system) or enter system settings (Mac system) and select display modes such as copy, extended or second screen only.
