Working with PC
This LCD supports Windows 7/8/8.1/10 when working with PC via HDMI interface.：
1. Connect the TOUCH interface of LCD to the USB interface of PC. Waiting for a moment, The touch will be recognized by Windows automatically.
2. Connect the HDMI interface of LCD to the HDMI port of PC. About 10s later, you can see that the LCD display properly. If you need to output sound, you can connect to 3.5mm headphones through HP audio output port.
1) 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.
2) Some of PC cannot support HDMI screen Hot Plug. In this case, restart the PC can solve.
3) Sometimes LCD will flicker because of undersupplying from USB cable of PC. You need to connect an external power supply (5V/2A) to DC port.
- Display orientation
- You can adjust the display orientation by display setting.
- Touch orientation
- The physical button on the backside can be used to adjust the orientation of touch. You can hold it for 5s to change.
- You may need to test multi times for the correct orientation.
Working with Raspberry Pi
This LCD supports Raspbian/Ubuntu mate/Kali/Retropie/Windows 10 IoT Core. <
When working with Raspberry Pi, you should set the resolution of the LCD by yourself, or else the LCD screen will not work. For more detail information, please read the following section.
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.
- For Pi 4
[pi4] hvs_priority=0x32ff gpu_mem=448 max_usb_current=1 hdmi_group=2 hdmi_mode=77
- For others Raspberry Pi
[all] max_usb_current=1 gpu_mem=512 hdmi_group=2 hdmi_mode=87 hdmi_timings=2560 1 10 10 80 1600 1 4 4 4 0 0 0 60 0 128000000 5 framebuffer_width=2560 framebuffer_height=1600 max_framebuffer_width=2560 max_framebuffer_height=1600 hdmi_pixel_freq_limit=268500000 config_hdmi_boost=4 max_usb_current=1
- The config.txt file should be modified as this
- 5) Insert the TF card into the Raspberry Pi
- 6) Connect the Touch interface of the LCD to the USB port of Raspberry Pi.
- 7) Connect the HDMI interface of the LCD to the HDMI port of Raspberry Pi and then power on the Raspberry Pi, it can display normally after waiting for about a few seconds.
- Resolution of Ubuntu Mate OS or Windows 10 IoT Core OS can also be set properly by editing config.txt.
- For Pi Zero / Zero W: if you've used an SD card on a Pi 3 and then attached the card to the Pi Zero, the touch screen often doesn't work. In such cases, you have to write a fresh system image to the SD card. The first boot up must be done on the Pi Zero but not Pi 3, due to initialization for a corresponding device.
- The screen is displayed in portrait mode by default. For ease of use, the screen display direction can be adjusted, please read the following section.
Orientation setting(Working with Raspberry Pi)
- Display orientation
To change the orientation, you can add the following line to config.txt file and reboot.
- X can be 1: 90°; 2: 180°C; 3: 270°
For example, if you want to rotate it for 90 degrees, you can add the line display_rotate=1
And then restart the Raspberry Pi after saving.
- Touch orientation
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.
For this display, we provide two touch rotation methods.
Rotate by modifying the config.txt
sudo apt-get install xserver-xorg-input-libinput
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.
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"
Rotate by button
In some special systems, when you cannot rotate by modifying the software, you can press and hold the "Rotate Touch" button for 5 seconds to rotate touch. And you may need to test multi times for the correct orientation.
We recommend using the software modification method. Otherwise, when using the new system, it may cause touch reverse errors. At that time, you need to press and hold "Rotate Touch" to rotate.
Because this 9inch HDMI monitor has higher resolution, for better touching effect, we recommend you to set the icon and text bigger. We take Raspberry Pi OS (Raspbian) as an example. Note that this setting doesn't be supported by all the OS.
- Choose Menu -> Preferences -> Appearance Settings -> Defualts -> For large screens:Defaults -> OK
- Set the font of system
- Right-click taskbar -> Panel Settings -> Set the size of Geometry
Disable power saving
If you want to keep the display turning on all the time, you can disable the power-saving function.
Modify file lightdm.conf
sudo nano /etc/lightdm/lightdm.conf
Find the [SeatDefaults] option and uncomment the line"xserver-command", modify it as below:
Modify this code to
xserver-command=X -s 0 -dpms
- -s # –Disable the display protecting.
- dpms Disable power saving.
- On/OFF: Turn on/off the backlight.

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:
Beware of knock-offs
Please note that we've found some poor copies of this item in the market. They are usually made of inferior materials and shipped without any testing.
