Why Is My Mini Projector Only Showing a Desktop Background?

Mini projectors have become popular among people who want to enjoy their favorite movies, TV shows, and presentations on a bigger screen. However, a common issue that some users may face is when the mini projector only shows the desktop background and not other windows or applications. This issue can be frustrating, but there are several reasons why it might occur, and in this article, we will discuss some of the most common causes and how to fix them.

  1. Display Settings

One possible reason why your mini projector only shows the desktop background is that your display settings are incorrect. To fix this, go to your computer’s display settings and make sure that the multiple display option is selected. Also, check that the display settings are configured correctly for the projector.

  1. Duplicate Display

Another possible reason is that your computer is set to duplicate the display on the projector, which means that the projector will only display what is already being shown on the computer’s screen. To fix this, go to your computer’s display settings and select the “extend” option instead of “duplicate.”

  1. Outdated Drivers

If your computer’s display drivers are outdated or not installed correctly, it can cause issues with projecting the display. Make sure that your display drivers are up-to-date and correctly installed.

  1. Faulty HDMI Cable

A faulty HDMI cable can also cause issues with the display on your mini projector. Make sure that the HDMI cable is securely connected to both the computer and the projector, and that it is not damaged.
