Working with PC

This LCD can support Windows 7 /8 /8.1 /10 /11 system.

1) Turn on the backlight switch on the back of the LCD.

2) 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.

3) Connect the HDMI interface of the LCD to the HDMI interface of the PC.

Normally you can see an interface similar to the following figure. (Some PCs may need to be restarted to display.)


Windows Touch Calibration

Open the control panel - "change the view mode to small icons -" select Tablet PC settings - "select calibration under the display tab -" perform 16-point calibration and save the data.
Note: If you have already calibrated, you need to click "Reset" before you can calibrate it again. If the system has saved the calibration parameters when using our HDMI capacitive screen, you need to "reset" the calibration parameters, otherwise, the capacitive touch will be inaccurate. When the computer is connected to multiple displays at the same time, the cursor on the main display can only be controlled through this LCD, so it is recommended to set the LCD as the main display.

Working with Raspberry Pi

This LCD can support Raspberry Pi OS / Ubuntu / Kali / Retropie systems. When the LCD works on systems such as Raspberry Pi, the resolution must be set manually, otherwise, it will cause an abnormal display. There is no such problem when the LCD works on the PC version of Windows.

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_cvt 800 480 60 6 0 0 0

You must ensure that there are no spaces around the equal sign.
5. Insert the TF card into the Raspberry Pi and turn on the backlight switch on the back of the LCD.
6. Connect the Touch port of the LCD to the USB port of the Raspberry Pi.
7. Connect the HDMI port of the LCD to the HDMI port of the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds to display normally.

Calibration in Raspbian

Install related software:

sudo apt-get install xinput-calibrator
sudo apt-get install xserver-xorg-input-evdev
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo reboot
  • There will be an additional Calibrate Touchscreen in Menu->Preferences, run the demo to calibrate.
  • Perform touch calibration according to the displayed prompt. After calibration, there should be a good touch effect (if the error is relatively large, you can re-run the calibration procedure).
  • If you want to save these touch values, you need to create a new 99-calibration.conf file in the following path:
  • Save information similar to the following to 99-calibration.conf.
