Interface Introduction

User Guide

Working With Raspberry Pi

Hardware Connection

Connect the Touch port of the display to the USB port of the Raspberry Pi.
Connect the display to the Raspberry Pi via the HDMI interface.

Software Setting

Support Raspberry Pi OS/Ubuntu/Kali and Retropie system.
When LCD works with the Raspberry Pi systems, you must set the resolution manually. Otherwise, the resolution will be wrong and it will affect your experience.

1. Please download the latest image in the official Raspberry Pi website. 2. Download the compressed file on the PC and unzip it to get the ".img" file. 3. Connect the TF card to the PC and use SDFormatter to format the TF card. 4. Open Win32DiskImager, select the system image prepared in the first step and click "write" to program the system image. 5. After programming, you can open the "config.txt" file in the TF card root directory. Add the following code at the end of "config.txt", save it, and then safely remove the TF card.

hdmi_group=2
hdmi_mode=87
hdmi_cvt 1280 800 60 6 0 0 0
hdmi_drive=1

6. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds for a normal display.

Linux Software Brightness Adjustment

Using the DDC/CI program, here is an example of the ddcutil tool.

#Install ddcutil tool:
sudo apt-get install ddcutil -y
#Detect DDC/CI monitor support:
sudo ddcutil detect
#Adjust monitor brightness, <value> should be modified to 0-100 
sudo ddcutil setvcp 10 <value>

How To Use

Connect the Touch port of the LCD to the USB port of the PC, and Windows will automatically identify the touch function.

【Note】If the touch screen is blank, press the "Enter" key, and the text prompt will switch to the touch screen. (The screen which displays the text prompt will be used as a touch screen!)

Windows Software Brightness Adjustment

1. Download and install DDC/CI applications, such as the open-source Twinkle Tray.
2. Open the software dimming icon, it will recognize the Waveshare monitor and adjust the monitor backlight brightness by sliding the scroll bar.

3. You can also enter the DDC/CI application settings screen to enable contrast adjustment, volume adjustment, and other functions.
