Changing Resolution On The Raspberry Pi 4

Advertisements

I love running my Raspberry Pi’s Headless. Unless the Pi is giving me problems, a monitor usually is not attached. Since there is no monitor attached, the Pi will automatically set the resolution low. This usually does not cause many problems except when your running programs that require a higher resolution like WSJT-X. An easy way to fix this is to manually set the resolution in the config.txt file.

Open a terminal window and navigate to the /boot directory.

Type ” sudo nano config.txt “. This will open the config file in Nano editor. Once the file is open search for the line with the hdmi_group and hdmi_mode.

Remove the # next to each line to uncomment it. The number next to hdmi_group sets the hdmi output as a monitor or television. hdmi_mode sets the resolution and refresh rate. For a table that lists all mode settings click this link. The setting above are for a standard monitor running 1080p resolution.

With the resolution set higher, I can see all my screens while running WSJT-X.
