Example Code for Raspberry Pi-Screen Resolution Configuration

Tutorial

This screen supports three operating systems: Linux, Windows and MACOS. Among them, Windows and MAC systems can be set to configure the output resolution. Linux needs to be set by commands.

Raspberry Pi Tutorial

When you use the 10.1" screen on the Raspberry Pi, the resolution may not adapt. You need to manually configure the Raspberry Pi ’s HDMI output to reset the resolution. (Insufficient power will also prevent the screen from turning on.)

• Install the operating system image in the microSD card, we recommend the - Official Raspbian System , Click to read the tutorial Installing Tutorial.

• After the system image is installed, the microSD card will be divided into two partitions: the system image partition and the boot system boot configuration partition. We need to modify the system configuration file ** config.txt ** in the boot disk.

• Insert the SD card into the computer through the card reader, enter the boot disk, find the directory ** / boot / config.txt **, modify or add the following items: (If there is no config.txt file, please create a new one, the first file may need to be created when starting)

hdmi_group=2
hdmi_mode=87
display_rotate=3

display_rotate=0, 1, 2, 3 means 0, 90, 180, 270 degree rotating angle, please use 1 or 3 since this is a vertical screen.

• Save the data and plug microSD card into Raspberry Pi. Connect the screen to the HDMI/HDMI0 port, then we can see the desktop.
• For RPi 4 model B, there are 2 HDMI ports, we have to config it one by one.[HDMI:0]/[HDMI:1]

Windows and the other Systems

In the first usage with Windows and MacOS, please use the system screen rotation function.
