Check whether the laptop supports video input
Look for HDMI-in, USB-C video input, or Thunderbolt input support
If the laptop does not support video input, use remote desktop or screen-sharing software instead
Connect the source device to the laptop using the supported input port
Open the laptop’s display settings or the manufacturer’s input-switching app
Select the external input source if the laptop supports it
Use a capture card with a USB connection if direct video input is not supported
Connect the source device to the capture card
Connect the capture card to the laptop
Open the capture software on the laptop to view the screen
Adjust resolution and display settings as needed
Use keyboard shortcuts or display controls to switch between laptop display and input view if available
