How to use
Working with Windows PC
This LCD can support Windows 7/8 / 8.1 / 10 system.
1)Turn on the backlight switch on the backside of LCD.
2)Connect the Touch interface of LCD to the USB port of PC. Wait for a while, the windows will automatically recognize the touch function.
3)Connect the HDMI (Display) interface of LCD to the HDMI port of PC. About 10s later, you can see the LCD display properly.
4)Connect earphone to HP interface or 8Ω 5W Speaker to Speaker interface of LCD if audio output is required.
Note:
- When the computer is connected to several different displays at the same time, only this LCD can be used to control the cursor on the main display, so we recommended to set this LCD as the main display.
- Hot-Plug isn't supported by some PC, you can try to restart if LCD doesn't display after connecting
Working with Raspberry Pi
This LCD can support Raspbian / Ubuntu / Kali / Retropie and WIN10 IoT systems. When the LCD works on systems such as Raspberry Pi, the resolution must be set manually, otherwise, it will cause 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 on the Raspberry Pi official website.
1) Download the compressed file to the PC, and unzip it to get the .img file.
2) Connect the TF card to the PC, use SDFormatter.exe software to format the TF card.
3) Open the Win32DiskImager.exe software, select the system image downloaded in step 1, and click‘Write’ to write the system image. (refer to RPi Image Install about how to write image)
4) After the image has finished writing, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, then save and quit the TF card safely.
max_usb_current=1 hdmi_group=2 hdmi_mode=87 hdmi_cvt 800 480 60 6 0 0 0
【Note】There should not be spaces in both sides of equal-sign.
If the LCD cannot work with statements above when working with Pi 4, you can comment/remove statement dtoverlay=cv4-fkms-V3D on config.txt file and try again.
5) Insert the TF card into the Raspberry Pi
6) Connect the Touch interface of the LCD to the USB interface of the Raspberry Pi.
7) Connect the HDMI interface of the LCD to the HDMI interface of the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds until the LCD displays normally.
Configure orientation (Working with Raspberry Pi)
Display Rotating
Add this statement in the config.txt file (the config file is located in the root directory of the TF card, which is named /boot):
display_rotate=1 #1：90；2: 180； 3: 270
Note: For Raspberry Pi 4, you need to comment out dtoverlay=vc4-fkms-V3D.
#dtoverlay=vc4-fkms-V3D.
And then restart the Raspberry Pi after saving.
sudo reboot
Touch Rotating
After the display is rotated, the position of touch is incorrect because the touch doesn’t change with the display angle. So the touch also needs to be modified.
1.Install libinput.
sudo apt-get install xserver-xorg-input-libinput
If the system you installed is Ubuntu or Jetson Nano. The installation code is:
sudo apt install xserver-xorg-input-synaptics
2.Create the xorg.conf.d directory under /etc/X11/ (if the directory already exists, proceed directly to step 3).
sudo mkdir /etc/X11/xorg.conf.d
3.Copy the 40-libinput-conf file to the directory you created just now.
sudo cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/
4.Edit this file.
sudo nano /etc/X11/xorg.conf.d/40-libinput.conf
Find the part of the touchscreen, add the following statement inside, and then save the file.
Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
Similar to the picture below:
5. Restart the Raspberry Pi.
sudo reboot
After completing these steps. The LCD could rotate 90 degrees both display and touch function.
Note:
90 degree rotation: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
180 degree rotation: Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
270 degree rotation: Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"
