User Guide

Working With Raspberry Pi 4

Hardware Connection

  1. Connect the Touch port to the USB port of the Raspberry Pi.
  2. Connect the HDMI port to the HDMI port of the Raspberry Pi.

Software Setting

Raspberry Pi OS / Ubuntu / Kali and Retropie systems are supported.
When the LCD works on systems such as Raspberry Pi, the resolution must be manually set, otherwise, it will cause incorrect display resolution and affect the experience.

1. Please download the newest image from Raspberry Pi official website.
2. Download the compressed file to the PC and decompress it to get the .img file.
3. Connect the TF card to the PC, and use SDFormatter to format the TF card.
4. Open the Win32DiskImager.zip software, select the system image prepared in step 1, and click write to burn the system image.
5. 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, save and eject the TF card safely.

hdmi_group=2
hdmi_mode=87
config_hdmi_boost=4
hdmi_pixel_freq_limit=356000000
hdmi_timings=1536 0 500 66 158 2048 0 60 10 10 0 0 0 60 0 295000000 3
max_framebuffer_width=1536
max_framebuffer_height=2048
framebuffer_width=1536
framebuffer_height=2048

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

Display Rotation

If you're using a Pi4, you can rotate it by the following method:

  • 1. Open Screen Configuration.

  • 2. Set the rotation as shown below:

  • 3. After rotating and touching, it can be used normally.

If you're using a Pi3+, or older, rotate it via:

  • 1. Add statements to the config.txt file (the config file is located in the root directory of the TF card, ie /boot):
display_rotate=1 #1:90;2: 180; 3: 270
  • 2. Save and restart the Raspberry Pi:
sudo reboot

Rotate Touch

After rotating the display, the touch position is wrong because the touch does not change with the display angle. So you need to modify the touch. By taking a card pin or tweezers, press the following positions to touch and rotate.
(In order to avoid accidental touch, we hide the Rotate Touch button inside the case.)

Working With PC

Support Windows 11/10/8.1/8/7 System

How to Use

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

  • Note:
  • Some PCs do not support the plug-and-play function of HDMI devices, and it can be normal after rebooting the system.
  • If there is no sufficient power for the USB port, the LCD screen may flash. After connecting the 5V 1A power adapter to the Power port of the LCD, it can be normally used.

Windows Touch Calibration

Take Windows 10 as an example:

  • 1. Enter the Windows settings of the system, type in the search bar and click "Calibrate the screen for pen or touch input" (as shown in the picture below):

  • 3. The following text prompt will appear on the screen. Please tap the touch screen with your finger, and the computer will recognize it as a touch screen.
【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!)
