Playing movies or music on your laptop will use a lot of power. As such, some laptops are actually built to prevent the use of HDMI when the laptop is not plugged into a power source. So make sure your laptop has a working power cable. Doing this will also the laptop to run to maximum performance, as you won’t have batty-saving features interrupting the playback.

  • Restart both devices – As when faced with any technology issue, the first step is to restart the device. Even though your laptop should automatically recognize the connection, it sometimes doesn’t work like that. As such, restart both your laptop and the projector, but leave them connected. Start with the projector, and then turn on your laptop afterwards
  • Check the connections – Is everything plugged in properly? Sometimes you have to push the plug in further than you may think. It could have also slightly fallen out while you were positioning the equipment
  • Enable HDMI content – If it still doesn’t work after you have ensured the connection is secure, you may need to make sure your laptop is enabled to use HDMI. This can be enabled in your laptop settings
  • Check your cables – Are you using the correct cables? While you can use a Category 2 HMDI cable on a Category 1 connection, it doesn’t work the other way around. You may be trying to use an old HDMI cable with a new projector or laptop. This is likely to be the case if your picture is unfocused or there is a loss of audio.
