- 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 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:
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.
You might be wondering if the one you're watching or you've purchased in other non-official stores is original, feel free to contact us.
How to use
Working with Raspberry Pi
Hardware Connection
- 1. Connect the Touch interface to the USB interface of the Raspberry Pi.
- 2. Connect the HDMI interface to the HDMI interface of the Raspberry Pi.
Software Setting
This LCD can support Raspberry Pi OS/Ubuntu/Kali/Retropie systems. When the LCD works on systems such as Raspberry Pi OS, the resolution must be set manually, otherwise, it will cause an abnormal display.
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, and use SDFormatter software to format the TF card.
3) Open the Win32DiskImager 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.
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, power on it, and wait a few seconds for a normal display.
Backlight Adjustment
wget https://files.waveshare.com/upload/0/01/Brightness-HDMI.zip unzip Brightness-HDMI.zip cd Brightness-HDMI sudo chmod +x install.sh ./install.sh
Working with PC
Support Windows 11 / 10 / 8.1 / 8 / 7
1) 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.
2) Connect the HDMI interface of the LCD to the HDMI interface of the PC. Wait for a while, the windows will automatically recognize the display function.
Note:
1) When the computer is connected to multiple monitors at the same time, the touch effect of the 7-inch LCD will be applied to the main screen by default. If you need to specify the touch to the secondary screen, see #Calibration touch on Win 10 PC
2) Some of PC cannot support the HDMI screen Hot Plug. In this case, restarting the PC can solve.
3) Sometimes LCD will flicker because of undersupplying from the USB cable of the PC. You need to connect an external power supply (5V/2A) to the DC port.
Brightness Adjustment on Windows via Software
- 1. Download and unzip USB Brightness Adjustment Demo.
- 2. Enter "WS_USB_Brightness_Win.exe", and then Windows can recognize it normally and prompt "the device is connected". You can drag the slider to adjust the backlight.
Calibration Touch on Win 10 PC
Take the windows10 system as an example:
- 1. Enter the Windows settings of the system, type in the search bar, and click "Calibrate the screen for pen or touch input" (as shown in the picture below):
- 2. Click "Setup" in the pop-up "Tablet PC Settings" interface:
- 3. The following text prompt will appear on the screen. Please tap the touch screen with your finger, and the computer will recognize it as a touch screen.
【Note】If the touch screen is blank, press the "Enter" key, and the text prompt will switch to the touch screen. (The screen which displays the text prompt will be used as a touch screen!)
