If the system of the main control board can automatically identify the EDID for display, there is no need to set the relevant timing parameters additionally.
Otherwise, you can refer to the following EDID settings:
Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They're usually some poor copies of our early hardware revisions, and comes with none support service.
To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:
Please note that we've found some poor copies of this item in the market. They are usually made of inferior materials and shipped without any testing.
You might be wondering if the one you're watching or you've purchased in other non-official stores is original, feel free to contact us.
This product supports Windows 11/10/8.1/8/7 OS:
1. Connect the TOUCH interface of the LCD to the USB interface of the PC. Wait for a while, the windows will automatically recognize the touch function.
2. Connect the HDMI interface of the LCD to the HDMI port of the PC. About 5s later, you can see the LCD display properly. If you need the audio, you can insert 3.5mm earphones into HP ports.
Note:
1) When the computer is connected to several different displays at the same time, only this LCD can be used to control the cursor on the main display, so we recommended setting this LCD as the main display.
2) Some of PC cannot support the HDMI screen Hot Plug. In this case, restarting the PC can solve.
3) Sometimes LCD will flicker because of undersupplying from the USB cable of the PC. You need to connect an external power supply (5V/2A) to the DC port.
Supports Raspberry Pi OS/Ubuntu/Kali/Retropie Systems.
When working with Raspberry Pi, you should set the resolution of the LCD by yourself, otherwise, the LCD screen will not work. For more detailed information, please read the following section.
Please download the latest version of the image from the Raspberry Pi official website.
1. Download the compressed file to the PC, and extract the img file.
2. Connect the TF card to the PC and use SDFormatter to format the TF card.
3. Open the Win32DiskImager software, select the system image prepared in step 1, and click write to burn the system image.
4. After the programming is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt and save it.
hdmi_force_hotplug=1 config_hdmi_boost=10 hdmi_group=2 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0
5. Insert the TF card into the Raspberry Pi, connect the Touch port of the LCD to the USB port of the Raspberry Pi, and connect the HDMI port of the LCD to the HDMI port of the Raspberry Pi.
6. Power on the Raspberry Pi, and it will display normally after a few seconds.
Note:
Modification method: Open the config.txt file in the root directory of the TF card, and find the following line:
dtoverlay=vc4-kms-v3d
change into
dtoverlay=vc4-fkms-v3d
So in addition to the above modification, you also need to install the Raspicam camera library.
The installation method is as follows:
cd ~ sudo apt install cmake git clone https://github.com/raspberrypi/userland cd userland ./buildme sudo cp build/bin/* /bin/
Then execute the following command to shut down the system:
poweroff
Connect the Raspberry Pi camera to the CSI interface of the Raspberry Pi, power on the Raspberry Pi again, and after the system boots, execute the following command:
Take a picture:
raspistill -o image.jpg
Take a video:
raspivid -o video.h264 -t 10000
wget https://files.waveshare.com/upload/0/01/Brightness-HDMI.zip
unzip Brightness-HDMI.zip
cd Brightness-HDMI
sudo chmod +x install.sh
./install.sh
Note: Only the Rev4.1 version supports the USB dimming function.
wget https://files.waveshare.com/upload/0/01/Raspios-bookworm-7HP-Backlight.zip
unzip Raspios-bookworm-7HP-Backlight.zip
cd 32
#cd 64
sudo chmod +x 7H_Backlight
After running the above commands, enter the corresponding file folder and double-click the icon to run the driver.
Note: Only the Rev4.1 version supports the USB dimming function.
To work with Jetson Nano Developer Kit, you don't need to make software configurations.
1) Connect the TOUCH interface of the LCD to the USB interface of Jetson Nano.
2) Connect the HDMI interface of the LCD to the HDMI interface of the Jetson Nano and then power on the Jetson Nano. After about 5 seconds, you can see the LCD display normally. If you need to output sound, you can insert 3.5mm earphones into the HP audio output interface.
Note:
1) If the LCD flickers, it may be due to the insufficient power supply of the Jetson Nano's USB interface. It can be solved normally after connecting to an external 5V/2A power supply through the DC interface of the LCD.
2) When the HP audio interface is in use, it may be necessary to set the sound output settings in the system.
Add the following command to /boot/config.txt:
disable_splash=1
Replace the custom image with the image in this directory /usr/share/plymouth/themes/pix/splash.png.
Test environment: 2022-04-04-raspios-bullseye-armhf 32-bit system
Supported models: Support Waveshare DSI LCD, DPI LCD, and HDMI LCD capacitive touch screen series.Only support 32bit system
wget https://files.waveshare.com/upload/1/18/Evdev-right-click-emulation.zip
unzip Evdev-right-click-emulation.zip
cd evdev-right-click-emulation
sudo apt install build-essential libevdev2 libevdev-dev
cd 'evdev-right-click-emulation'
sudo cp 'out/evdev-rce' '/usr/local/bin/'
sudo chmod +x '/usr/local/bin/evdev-rce'
Enter the command:
sudo evdev-rce
After running, you can touch and long press to realize the right-click function.
sudo usermod -G 'input' -a pi
echo 'uinput' | sudo tee -a /etc/modules
sudo nano /etc/udev/rules.d/99-uinput.rules
Add in 99-uinput.rules file.
KERNEL=="uinput", MODE="0660", GROUP="input"
save it and run it in the terminal.
sudo udevadm control --reload-rules sudo udevadm trigger
Then reboot:
sudo reboot
Run after reboot (no sudo needed at this point).

After running, you can touch and long press to realize the right-click function.
Enter the terminal:
sudo mkdir ~/.config/autostart sudo nano ~/.config/autostart/right_click.desktop
Add the following in right_click.desktop.
[Desktop Entry] Version=1.0 Type=Application Name=evdev-rce GenericName=Enable long-press-to-right-click gesture Exec=env LONG_CLICK_INTERVAL=1000 LONG_CLICK_FUZZ=200 /usr/local/bin/evdev-rce Terminal=true StartupNotify=false #If you want to modify the sensitivity, you can modify the size of the two parameters, LONG_CLICK_INTERVAL=1000 LONG_CLICK_FUZZ=200.

It depends on the system, if the system has hibernation, the screen will also be black. If it is the official system of Raspberry Pi, the default is about ten minutes without action to have hibernation.
Normally, when the screen is powered on and an HDMI signal is recognized, it will light up automatically without pressing a button.
