Even though the Raspberry Pi tries to automatically work out the best resolution to use for a screen, this isn’t always a perfect science.
Displays can sometimes provide weird information back to the device that makes it difficult to work out the correct resolution.
With this guide, we will be showing you how you can manually set the resolution of your Raspberry Pi.
Setting the resolution can be done through both the desktop interface and the terminal.
Using the terminal, you will be shown how to use the Raspberry Pi configuration tool as well as how to modify the /boot/config.txt file directly.
