As display technology has evolved, there are now many display options available to consumers. One of the most popular display options is TV screens.
Laptop users can display a laptop screen image through a connected projector for presentations or meetings.
This process may vary based on the type of display you want to use; it usually involves using an external display port or HDMI output from your display device.

To display your laptop screen with a connected projector, check if your computer has a “Projector” option in its display settings menu.
Once this setting is enabled, connect the display cable from your projector to the video-in port on your laptop or computer tower (if you have one).
Select “External Display” as the new display mode and press enter on your keyboard. Your display should be projected on the screen right away.
If your display device has no “Projector” option in its display settings, you may need to get a special display adapter for it.
Depending on the type of display you want to use, display adapters are available with different external display ports and HDMI outputs.
For example, if you have an older laptop that does not have an HDMI output or display port, you can get a VGA display adapter for it.
Plug the display cable into your laptop’s video-in port and plug the other end into your projector’s video-out port (the same way you would connect two game consoles).
Then select “External Display” as the new display mode and press enter on your keyboard; your display should be projected on the screen right away.

If your display device does not have enough display adapters or display ports, you can also use external video converters for it.
These converters are available in different types depending on how many display devices you want to connect to your laptop display.
For example, if you want to connect two displays, you can get a “Dual Monitor” converter from one of these display adapter makers: Belkin, Startech .com, and Cable Matters.
Another example is if you want to use three or four display screens at once, get a “4 Port Display Splitter” converter from StarTech .com.
After getting one of these converters, simply plug all your display cables into its ends and the display converter itself into your display device’s video-in port.
Then select “External Display” as the new display mode and press enter on your keyboard; your display(s) should be projected on the screen right away.
If you are using Windows 7, check if one of these display formats is supported through your display or display adapter: Extended Desktop, Mirror, or Clone.
These options can be selected in Windows’ primary display settings menu. For more detailed instructions, consult your owner’s manual for how to use these different display modes on your laptop or computer monitor.
