I have a touch screen... model is in my signature... and it is plugged in with both a USB cable and a high def cable of some sort HDMI or some other one. USB is for the touch control and a USB hub.

The problem...
The computer makes it run as a USB display as well as a regular display.

I regularly go into device manager and disable the USB display, but it gets rediscovered any time there are Windows updates. The result is that the computer extends my desktop... showing the same monitor as two monitors. I can move the mouse to a place I cannot see. Disabling the USB version of the monitor is then a recurring task.

I tried just disconnecting the high def cable, but then the display was laggy and cumbersome and not as nice looking.

Any ideas how I can ensure that USB display adapters are never used?

On a separate note, sometimes my mouse pointer goes to the top center of the touch screen. This is irritating. Touching the screen is usually sufficient to resolve it.

Some of these monitors apparently install the USB connection as a service. If so, and if you can find it, you may be able to set it to start manually instead of automatically.

Ah thanks. I'll hunt for that.

I have not been able to put my finger on any service that is causing the problem.
