Working with Raspberry Pi
Support Raspberry Pi OS/Ubuntu/Kali and Retropie system.
1. Please download the latest version of the image from Raspberry Pi official website.
2. Download the compressed file to the PC and extract it to get the .img file.
3. Connect the TF card to the PC, and use the SDFormatter software to format the TF card.
4. Open the Win32DiskImager software, select the system image prepared in step 1, and click "write" to program the system image.
5. After the programming is completed, open the config.txt file in the root directory of the TF card. Please add the following code at the end of config.txt, save and safely eject the TF card, and then insert the TF card into the Raspberry Pi.
hdmi_group=2 hdmi_mode=82 hdmi_cvt 1920 1080 60 6 0 0 0
6. Connect the 12V power supply to the DC interface of the LCD, and you can see that the LCD backlight is lit normally.
7. Connect the Touch port of the LCD to the USB port of the Raspberry Pi, and the HDMI port of the LCD to the HDMI port of the Raspberry Pi.
8. Power on the Raspberry Pi and wait for a few seconds to display normally.
Linux Software Dimming
- Using the DDC/CI demo, here we take the ddcutil tool as the example:
#Install ddcutil tool: sudo apt-get install ddcutil -y #Detect whether it supports DDC/CI monitors: sudo ddcutil detect #Adjust the monitor brightness, <value> needs to modified as 0-100. sudo ddcutil setvcp 10 <value>
For more ddcutil function commands, you can refer to http://www.ddcutil.com/commands/.
Working with Horizon Sunrise X3 Pi
Support Ubuntu20.04 system.
Please download the ubuntu20.04 image from here, and then program the system according to the user manual.
- How to use:
- 1) Connect the 12V power supply to the DC port of the LCD, and you can see the LCD backlight is on.
- 2) Connect the HDMI interface of the X3 Pi to the USB interface of the LCD.
- 3) Connect the HDMI interface of the X3 Pi to the HDMI interface of the LCD.
- 4) Connect the 5V power supply to the X3 Pi and power on it.
Note:
- If you connect the LCD after booting X3 Pi, and there is no image on the LCD, you need to reboot the X3 Pi.
Working with PC
Support PC Windows 11/10/8.1/8.7
Usage steps:
1) Provides 12V to the DC port of the LCD and you can see its backlight is on.
2) Connect the TOUCH port of the LCD to the USB port of the PC. Please wait for seconds and Windows can automatically recognize the touch function.
3) If you want to use HDMI communication, you can use the HDMI port of the LCD to the PC, and you can see the LCD display normally after a few seconds. If you want to output the audio, you can connect 3.5mm earphones to the HP audio port.
Note:
1) When the PC is connected to multiple monitors at the same time, the cursor on the main monitor can only be controlled through the LCD, so it is recommended to set the LCD as the main monitor.
2) Some PCs do not support plug-and-play with HDMI devices. Generally, they can be used normally after restarting the system.
3) The HP audio output can be used normally only during HDMI communication.
Windows Software Dimming
- 1. Download and install the DDC/CI application, for example, 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 interface to enable contrast adjustment, volume adjustment, and other functions.
Keys
- Power: Turn on/off LCD. Switch the backlight power on and off. If you do not need to use the LCD for a long time, you can use this button to turn off the backlight and reduce power consumption.
- Menu: Open OSD Menu/OK. Press the key to open the OSD menu. When using the menu, it can also be used as a confirmation button.
- Up/Left: Direction buttons
- Down/Right: Direction buttons
- Exit: Return

Part Name:
1. Equipment case
2. Countersunk head machine screw
3. Standoffs
4. Adhesive sponge
5. Acrylic board (thickness 5mm and above)
6. Round head machine screw
7. HDMI LCD
Assembly Instructions
1. Fix the Copper pillar ③ on the back of the Equipment case ① with countersunk screws ②, and then embed HDMI LCD ⑦ into the Equipment case ① and bond it firmly. The countersunk screw holes on the casing will be blocked by the edge of the screen. So the screws cannot be seen on the exterior side.
2. Paste the Adhesive sponge ④ with an appropriate thickness on the Acrylic board ⑤, pay attention to the position of the paste to avoid the PCB board, and finally fix it on the copper pillar ③ with the Round head machine screw ⑥. After assembly, make sure that the sponge is fully attached to the back of the LCD.
3. The opening holes on the acrylic board avoid the components on the PCB board to facilitate the connection between the interface and the device.
Note: The LCD display surface cannot be installed parallel to the ground, otherwise it will fall off under the action of gravity. In addition, when it needs to be installed at an angle, the back of the LCD screen should be kept at least less than 75 degrees from the horizontal.

60Hz
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.
The 15.6inch HDMI LCD (H) (with case) is powered by two parts, one is the POWER interface, which needs to be connected to a 12V 1A power adapter, and the working current is about 12V 0.6A during normal operation.
The other is the TOUCH interface, which generally needs to be connected to the USB interface of the host. Power is drawn through the USB interface. The working current is about 5V 80mA.
Remove the triode shown in the figure below, and solder the PWM pin on the pad indicated by the arrow on the right.
Execute the following command on the Raspberry Pi terminal:
gpio -g pwm 18 0 gpio -g mode 18 pwm (occupied pins are PWM pins) gpio pwmc 1000 gpio -g pwm 18 X (X ranges from 0 to 1024), 0 is the brightest, 1024 is the darkest
12V 1A outer diameter 3.5 and inner diameter 1.35. If you want to use other power supplies, you need to ensure that the power supply ripple is within ±5%
