I am deploying a web application in a production environment, and am considering touchscreen support for ease of use. I've never used one before, and am wondering on which cable it transfers touch signal to the computer. Probably an auxiliary USB cable? I don't expect the HDMI cable to handle such function.
By the way, does Android have generic driver support for these monitors? I intend to replace Windows 10 PC with cheap Chinese Android boxes (usually Android 7.0 and above) because of their tiny size and low power consumption.
