  • Besides, there are 2 files of each video if it is downloaded from the IOS system, one of which shall be able to play;

However, if the problem still exists, you may go through the details listed below.

1. Projector Not Set Up

If you want to watch videos through the projector, you have to connect it to the source of the video. This can be your phone or laptop, the methods of connection are very similar. Connecting the devices together usually need some kind of cables or adapters, and you have to be sure that you are using the correct cables for the connection.


  • Plug in the projector video connection as required in the projector's video port.
  • Click on Start and click Settings
  • Select System and then click on Display
  • After which you then select Connect to a wireless display
  • Then choose your projector
  • You can now make any necessary modifications to the display size as required.


2. Does the Device Connect to the Correct Source?

If the video still doesn't play on the projector, you may have to confirm that the correct connections are made. It is possible that in the moment of rush, you accidentally made some wrong connections or use the wrong cables and adapters.

  • Check whether the cables and adapters are properly plugged in and into the correct ports.
  • Also take note of the cables and/or adapters that are used for the connections and ensure that the correct ones are used.For example, if the projector is one that makes use of a USB type C port, it will only display videos when connected through the USB type C video cable and not the USB type C charge cable. Also, if the projector is to be connected using a VGA port, it is important that you use the VGA to HDMI converter. Using the HDMI to VGA converter cable will not display videos.

3. Source Device Does Not Output Video Signal

If all the connections seem to be accurate and the video still isn’t playing, it is possible that the device connected to the projector is not sending out any video signal.


  • It could be that you selected the wrong input mode for the projector. If your projector has multiple input modes, you are sure that you select the correct input to which the cable is connected to.
  • Likewise it is possible that either the projector or the video card is bad. The motherboard of your laptop might be spoilt and is preventing the video signal from reaching the video card and the projector. The simplest way to check which is defective is by connecting them to a different device. If your projector works with another laptop, then the fault is from the laptop. But if the laptop works with another projector then you have to fix the projector.

4. Resolution of the Laptop too High

Some projectors cannot play certain video resolutions, those kinds of videos may fail to play when connected. The simple way to fix it is to reduce the resolution to one that can be played on the projector. It is normally better to set the resolution at 720p or 1080p.

  • Press Windows
  • Search for adjusting screen resolution and click enter
  • Find display on the drop down menu
  • Choose the appropriate device resolution
  • Click Apply and click Ok

5. Display Driver Has Not Been Upgraded

The projector and laptop can be incompatible to display videos at the same time. This is normally due to the fact that the brands of the video card and drivers are different. To beat this, check the manufacturer's website for updated drivers and download the latest versions.

  • Click on Windows+R to open Run.
  • Type and press OK to open the device manager.
  • When you are in the device manager, open display adapter. Right-click on it and select update driver.
  • Then search automatically for an updated driver.
  • Let the system download the needed updates and install them. After which you should restart the system and confirm the changes.

If updating the driver doesn't still allow the video to play on both devices at the same time, then the viable option is to allow the video to play only on the projector.

  • Depending on the brand of the system, you can switch between screens by using the Fn and one of the function keys. This will allow you to choose whether to play only on the laptop screen, on both the laptop and projector screen or whether you will be playing using the projector screen only.
