  • Step 1: install the official image of Raspbian/Ubuntu                                                                      
1)Download the latest Raspbian or Ubuntu image from the official website https://www.raspberrypi.org/downloads/
2)Format the TF card with SDFormatter,
3)Use Win32DiskImager to burn the official image to the TF card.
  • Step 2, modify the "config.txt"                                                                               
After the step 1 completion of burning in the CD Driver in the folder "show-LCD.tar.gz" copy to TF-card root directory,

  • Step 3: insert the SD card into the raspberry pie and connect the hardware as shown in the picture:


  • Step 4: power the raspberry, connect the mouse keyboard, and open the terminal terminal terminal on the raspberry pie: 


  • Step 5. Enter the following instructions in the terminal terminal:
cd /boot
cp LCD-show.tar.gz ~
cd ~
sudo tar zxvf LCD-show.tar.gz 
cd LCD-show/
sudo ./MPI3508-show

How to use as PC monitor

Connect the computer HDMI output signal to the LCD HDMI interface by using the HDMI cable
Connect the LCD's USB Power interface to the USB port of the device
If there are several monitors, please unplug other monitor connectors first, and use LCD as the only monitor for testing.

Question: Using the Raspberry Pi image provided by the CD/net disk, cannot use the LCD normally.


  • Confirm that the hardware connection is correct and the contact is good.
  • Determine whether TF card is normal and whether the system is started normally.
  • The PWR lamp is always bright when the Raspberry Pi is started, and the ACT light is flashing.If you find both lights on,

it may be the TF card does not successfully burn the image file,or that the TF card is not in contact with the Raspberry Pi.

  • Recommend using 5V 2A power adapter to power the Raspberry Pi.
  • If you use a computer USB interface, you may not be able to activate the Raspberry Pi due to insufficient power supply.

Question: What is the reason for the LCD not displayed using the image provided by the Raspberry Pi official?


  • LCD needs to be installed driver to display correctly, please refer to "How to install the LCD driver (En)" related documentation.
  • It is recommended to use the image file provided by us first to test. After the test is passed, use the image file of Raspberry Pi official and installed the driver.

Question: How to switch back to traditional monitor for display?


  • Please refer to "How to install the LCD driver (En)" related instruction document, and use the following command:
    sudo ./LCD-hdmi

Question: Why the LCD works but flickers?


  • This problem is likely due to insufficient power supply.
  • If you are using the Raspberry Pi, please use the power supply of 5V full 2A to power the Raspberry Pi,
and connect the Raspberry Pi and the LCD by the short USB cable we provided.
  • If it is used as a computer monitor, do not use poor quality USB cable or extension cord connection,
do not receive extend the USB port to get electricity, please use the USB cable we provided.

Question: Why the Raspberry Pi unable to work properly after updating the Raspbian system?


  • The update needs to be done in the following manner, otherwise the image cannot run:
    sudo apt-mark hold raspberrypi-bootloader
    sudo apt-get update
    sudo apt-get upgrade

Question: Why the LCD is connected to the computer HDMI, but cannot be displayed normally?


Make sure the HDMI interface of the computer can be output normally.

The computer only connects to the LCD as a display device, and does not connect to other monitors (unplug other monitors).

Connect the USB first, then the HDMI.

Try to restart your computer.

You must use the Windows operating system. 

Question: How to turn on the Bluetooth function on the Raspberry Pi?


  • Method 1: upgrade to the official latest image of the Raspberry Pi (the Bluetooth function has been turned on by default after 2016-05-27-raspbian-jessie);
  • Method 2: manually turn on Bluetooth.
    sudo apt-get install pi-bluetooth
    sudo apt-get install bluetooth bluez blueman 
    systemctl status bluetooth
    sudo systemctl start bluetooth
    sudo reboot 

Question: Why unable to display full screen or incomplete when using 5”, 5”-B, 7”-B, or 7”-C HDMI screen?


  • Check if the HDMI is plugged in and output is normal.
  • Open the config.txt file in the TF card root directory to check the HDMI configuration.
  • 5", 5"-B and 7"-B 800*480 should be configured as follows:
    hdmi_cvt 800 480 60 6 0 0 0
  • 7"-C 1024*600 should be configured as follows:
    hdmi_cvt 1024 600 60 6 0 0 0
