PC and beamer: Setting the right resolution

by Pramith

By being able to set the resolution of your PC and that of the beamer independently, you always project an optimal image. This way you can read your notes well from your computer without your audience having to squint.

Adjust the resolution of beamer and PC optimally

If your notebook only manages a resolution of 1600 x 900, your beamer can still project an image of 1920 x 1080, i.e. Full HD (or higher) onto the screen. The different resolution settings are made possible by duplicating the display. This way, each unit retains its native resolution:

  • Connect the projector to your PC and wait until the device is recognised.
  • If a distorted picture appears (on the projector or on the computer), press the [Windows]+[P] keys simultaneously.
  • Select “Duplicate” as the display option.
  • To set the resolution manually, go to the display settings. To do this, right-click anywhere on your desktop and select “Display settings”.
  • Click on “Adjust resolution” on the left side.
  • Here you can see the current resolution for your PC and for the projector.
  • Use the slider to change the resolution so that you get a clear picture. For most cases, the settings recommended by Windows are suitable.
