Touch Settings on Win 10 PC

Some users want to connect more than one display to their PC. Here we talk about how to setting the touch to make the touchscreen control its screen separately.

  • Connect touchscreen to PC. Here we use a standard PC monitor and connect a 7inch HDMI LCD (C) for example. We make the monitor as the main screen and the touchscreen as a secondary screen.
  • By default, The touchscreen can only control the cursor on the main screen. Here we set it to control the secondary screen.
  • Open Control Panel and search Tablet PC setting on the control panel and open the tool.


  • Click button "Setup..." to set the touchscreen


  • After clicking the setup you can find that it is prompt on your first screen with white color background and other screens are white.


  • If we want the touch of the touchscreen to control the desktop of the touchscreen itself. Just press Enter key to pass the first screen. And the second screen, when you find that the black text is displayed on the touchscreen, just touch the center of the touchscreen to finish this setting.
  • After this setting, the touch on the screen will just control this touchscreen even though it is not the main screen.

Note:

1 If the first screen and the second screen are touchscreens as well, you can touch them when the text is displayed on the screens. Then you can find that all the touchscreen can work.

2 This method is just tested on win 10 PC.

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.
max_framebuffer_height=1480
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_timings=320 0 80 16 32 1480 0 16 4 12 0 0 0 60 0 42000000 3


You must make sure that there are no spaces on either side of the equal sign.

Note:

  • If you are using Pi4 or higher, the HDMI cable needs to be connected to the HDMI0 port of the Raspberry Pi (near the power port)
  • 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.
