In this article

1. Check for Loose Cables

Users who connect their projectors with HDMI and VGA cables should check that those cables aren’t in any way loose.

Check that the cables are securely connected with their required ports on both PC and projector. If not, unplug and the cable and then plug it back in again to ensure a secure connection.

2. Switch the Display Mode

  1. Press the Windows key + P hotkey, which opens the sidebar shown directly below.
  2. The Duplicate display mode option there is the one most widely utilized for projector presentations.
  3. So, that’s probably the best display mode option to select if it’s not already selected.

Some users might need to adjust their display mode settings to fix the projector’s display.

3. Update graphics card and port adapter drivers

  1. Press the Windows Key + S and type in Device Manager.
  2. Open the Device Manager and search for the display adapters.
  3. Right-click on the ones you wish to update and select Update driver.

A projector display error might also pertain to a graphics card or HDMI/VGA port adapter drivers.

Update drivers automatically

To check if those drivers need updating, use third-party driver updater software that automatically scans in seconds.

Updating drivers manually can be a time-consuming task. To be sure that all the work is safely made use a professional tool whose primary function is scanning for old drivers and updating them.

So, the most suitable software that can manage your drivers and update each one individually is undoubtedly Outbyte Driver Updater.

4. Turn on the PC’s Video Output

Some users might need to turn on their desktop’s or laptop’s video output to enable projection. To do that, users usually need to press an Fn hotkey combination.

For example, Acer laptop users can press an Fn + F5 hotkey to turn on the video output.

However, the video output hotkey varies between different PC brands. Users can check their PC manuals for further video output hotkey details.

5. Check if the Projector’s Standby Mode is On

The projector might be on standby mode. Users can wake up a projector in standby by pressing its standby mode button.

If you’re not sure where the standby mode button is, look through the projector’s manual for further details. This button differs from device to device.
