Three common methods for projecting computer screens onto televisions｜BJCast

There are three common methods for projecting a laptop screen to a TV, including wired projection, wireless projection, and using a screen mirroring device. The following are the detailed steps for each method:

Wired screen projection

1. Hardware preparation:

   • Ensure that the TV has an HDMI input port. If the TV does not have an HDMI port, an adapter or converter needs to be purchased.
   • Prepare an HDMI cable to connect your laptop and TV.

2. Operation steps:

   • Insert one end of the HDMI cable into the HDMI output port of the laptop.
   • Insert the other end of the HDMI cable into the HDMI input port of the TV.
   • Open the settings on the TV and switch the signal source to HDMI.
   • Open the projection settings on the laptop and select “Copy” or “Expand” mode to project the computer screen content onto the TV.

Wireless screen mirroring

1. Hardware and network preparation:

   • Ensure that both the laptop and TV are connected to the same Wi Fi network.
   • If the TV does not support direct wireless screen mirroring, it may be necessary to purchase wireless screen mirroring devices (such as Chromecast, Apple TV, etc.).

2. Operation steps (taking Windows system as an example):

   • On the laptop, press the “Win+P” key combination to access the projection settings.
   • Select ‘Connect to wireless display’ or similar options.
   • The computer will automatically search for nearby wireless display devices, find the TV, and click connect.
   • Follow the prompts on the TV to complete the connection process.

   For Mac users:

   • If the TV supports AirPlay, you can directly turn on the “AirPlay” function on your Mac and select the TV for screen mirroring.

Use a screen mirroring device to project the screen

1. Hardware preparation:

   • Purchase a screen sharing device, which typically consists of a transmitter and a receiver.
   • Prepare connection cables to connect the transmitter to the laptop and the receiver to the TV.

2. Operation steps:

   • Connect the transmitter to the laptop via a connecting cable.
   • Connect the receiver to the TV via a cable and turn on the power.
   • Open the settings on the TV and switch the signal source to HDMI or other corresponding input source.
   • Press the button on the transmitter to connect the receiver. After successful connection, the screen content of the laptop will be projected onto the TV.

Through the above three methods, laptop users can easily achieve screen mirroring to the TV, enjoying a larger screen and more comfortable viewing or office experience.
