User Guide

Working with Raspberry Pi

Hardware Connection

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

Software Setting

Raspberry Pi OS / Ubuntu / Kali and Retropie systems are supported for Raspberry Pi.
When the LCD works on these systems of Raspberry Pi, the resolution must be set manually, otherwise, it will result in incorrect display resolution and affect the experience.

Please download the newest image from the Official Raspberry Pi website.
Download the compressed file on the PC and unzip it to get the .img file.
Connect the TF card to the PC and use SDFormatter to format the TF card.
Open Win32DiskImager, choose the image prepared in the first step, and click "Write" to program the system image.
After programming, open the config.txt file in the root directory of the TF card and enter the following codes at the end of config.txt. Then, save and safely eject the TF card.

hdmi_group=2
hdmi_mode=87
hdmi_force_hotplug=1
hdmi_timings=800 0 218 218 218 800 0 16 16 16 0 0 0 60 0 74250000 0
hdmi_drive=2

6. Insert the TF card into the Raspberry Pi, power up the Raspberry Pi, wait for a few seconds normally and then it will display normally. Due to the circular screen feature, it is recommended to use the Raspberry Pi remote login tutorial for power-on setup.

Working with PC

Support Windows 11/10/8/8.1/7

How to Use

1. Connect the Touch interface of the LCD to the USB interface of the PC, and Windows will automatically recognize the touch function.
2. Connect the LCD's HDMI interface to the PC's HDMI interface, and Windows will automatically recognize the display function.

• Note:
• Some PCs do not support HDMI devices plug-and-play, generally after rebooting the system can be used normally.
• If the power supply of the USB interface is insufficient, the LCD will flicker, after connecting the external 5V 1A power adapter to the LCD's Power interface, it can be restored to normal use.

Windows Touch Calibration

Take Windows 10 as an example:

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

• 2. Click "Setup" in the pop-up "Tablet PC Settings" interface:

• 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.
