To get your copy you can just cut and paste, no download needed. I will illustrate a few possibilities just by giving you a commented file here (in a box). What you put in it depends on what you want to do. Lets create a python program called \home\pi\autoexec.py.

If you have run into any issues with this guide, feel free to drop a comment below.I will assume that you have a version of Python installed ( I like For Python I like the Spyder environment as described in Graph Instructable Views with Python Screen Scraping by russ_hensel ) and have at least some idea of how to use it. Using this key will make the Raspberry Pi ignore our boot configuration file and load up with the default settings.Īt this point in the guide, you should now have successfully managed to change the resolution on your Raspberry Pi. If for some reason your display stops working after the change you can try holding the SHIFT key during startup. Now to apply the new resolution to your Raspberry Pi, you need to restart it using the command below. Once you have set the HDMI mode and group, we can now save the file by pressing CTRL + X, then Y, followed by the ENTER key.ħ. Make sure that you replace with the number you found using our tables above. Once you have found the hdmi_mode number for your resolution, we can now go ahead and set it in the boot configuration file. To use this hdmi_enable_4kp60=1 must be set in /boot/config.txt.Ĥ. Use this when dealing with two 4k displays. Use this table to find the “ hdmi_mode” value for your resolution that is required for the next step.

If you want to view the full hdmi_mode table, then view the official Raspberry Pi Video documentation. We do this by modifying the hdmi_mode variable in the config file.īelow we have a trimmed down table showing some of the more used resolution settings for the Raspberry Pi. With the HDMI group chosen, we need to select the resolution. If you are unsure, you can see the supported resolutions in the tables below.ģ. Use the replacement for the HDMI group that you intend to use.

Next, you must work out if you want to use the CEA or DMT HDMI groups.ĬEA stands for Consumer Electronics Association and is the display standard that is typically used on a TV. If you are doing this on your Raspberry Pi, you can run the following command. Begin by modifying the /boot/config.txt file. Please note that this section can be a little tricky as there is much more to take in.ġ. You can edit this file directly on the SD card if you don’t have easy terminal access.

It is also possible to set the resolution of your Raspberry Pi without using the desktop interface or the raspi-config tool. Modifying the Boot Configuration to Set the Resolution If, for some reason, your screen will no longer display anything, try holding the SHIFT key during startup to revert to the default settings. Once you Raspberry Pi has finished restarting, the device should now be using the resolution that you set. While on the desktop interface of your Raspberry Pi, click the icon in the top-left hand corner of the screen.Ĭlicking this icon will bring up the start menu. In this section we are going to show you how to set the resolution of the screen using the desktop utilities.ġ. Changing the Screen Resolution using the Desktop If you are not using Raspbian Buster, try upgrading to Buster by using our guide.

We tested this guide on the Raspberry Pi 3 and the Raspberry Pi 4 using the latest version of Raspbian Buster. Here is a list of the equipment we recommend for this guide on setting the screen resolution of your Raspberry Pi. 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. Setting the resolution can be done through both the desktop interface and the terminal. With this guide, we will be showing you how you can manually set the resolution of your Raspberry Pi. 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.ĭisplays can sometimes provide weird information back to the device that makes it difficult to work out the correct resolution.
