Adjust the Resolution of Raspberry Pi 3

Step 1: Open config.txt There are two methods to do so. Method A: First prepare a computer on Windows, Mac or Linux, and a TF card on which the Raspbian system has been burnt. Plug the TF card into the computer with a card reader. Now, open /boot and find the config.txt file. If your computer runs on Windows, DO NOT open the file by Word (also better not notepad) in case of format issues. You are advised to use other edit tools like Notepad++ .

Method B: Log in to Raspberry Pi remotely. Run the command to edit config.txt.

sudo nano /boot/config.txt
