Instructions
Working with PC
This LCD can support Windows 7/8 / 8.1 / 10 system.
How to use:
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.
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.
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.
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 1024 600 60 6 0 0 0 hdmi_drive=1
5) Insert the TF card into the Raspberry Pi
6) Turn on the backlight switch on the back of the LCD.
7) Connect the Touch interface of the LCD to the USB interface of the Raspberry Pi.
8) 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.
Rotation(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
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"
About the version
Rev3.1 version
- The Rev3.1 version mainly changes the touch chip of the Rev2.2 version from GT811 to GT911. The touch effect is better, and the anti-interference ability is enhanced at the same time.
- This version is fully compatible with Rev2.1 and Rev2.2, and users can replace it with confidence.
Rev2.2 version
- Rev2.2 version mainly adds VCOM adjustable potentiometer and related circuits of electromagnetic compatibility on the basis of Rev2.1.
- This version is fully compatible with the Rev2.1 version, and users can replace it with confidence.
Rev2.1 version:
- Upgrade to IPS screen, with the larger viewing angle and the clearer display effect, I believe you will like it.
- Use standard HID protocol, you can transplant your own system conveniently.
- Using with Raspberry Pi, it supports Raspbian / Ubuntu / Kali / Retropie and WIN10 IoT, single touch, no need to install any drivers.
- Using as a computer monitor, it supports Windows 10 / 8.1 / 8 / 7, five-point touch, no need to install any drivers.
Rev1.1 version:
- Using private HID protocol, it is difficult to transplant to your own system
- Using with Raspberry Pi, you need to install a driver when the display connects to Raspbian or Ubuntu systems. and it doesn't support Kali, Retropie, and Windows 10 IoT.

Anti-Piracy
Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They're usually some poor copies of our early hardware revisions, and comes with none support service.
To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:
