Recently, I noticed that in my PC having Windows 10 Pro, in the Control Panel it is written Pen and Touch : Touch support with 20 touch points. See this screenshot
But, after checking the monitor many times I found that it is not registering any touch input. So, why is the OS telling that the monitor supports upto 20 touch points?

Windows might believe you have touch support because you have some touch device or trackpad or stylus. The touch device does not have to be the screen. On some Dell computers Windows misidentifies the hardware and enables touch when there is none, especially on laptops, perhaps because it misidentifies the laptop model.
If your computer is not touch capable on any device, it would be best to disregard this false indication.
If ignoring this problem is not a solution, because other applications may by mistake show a wrong interface specialized for touch devices, a false touch screen can be disabled:
- Start Device Manager
- Open "Human Interface Devices"
- For all HID-compliant touch screens (there may be more than one listed), in the Action tab select Disable device.
there is also an application called spacedesk which can use your phone/tablet as a secondary monitor it can cause Touch support with 20 touch points Because u actually have it when using phone/tablet as a secondary monitor
0You might have installed a 3rd party driver that causes your desktop OS to be identified as a touch-enabled device. One of such drivers / applications is e.g. spacedesk which allows you to use your smartphone or tablet as a secondary monitor. Only after uninstalling it entirely, other applications were able to tell properly that my Windows machine has no touch-support.
