My touch screen monitor has an area on the right part of the screen that will not respond to touch. My mouse is flickering all over the place and the dimensions of the screen change from full screen to 200 % back to 75% back to 150% in the space of a couple of seconds ( as it just did now) for no reason and in all programs. Since we use skype, the size of the screen will change back and forth for no reason. I get dialog boxes up on a working screen which seem to appear for no reason and flicker while they appear. I have run a complete virus scan. I am running windows 10. I do not game or watch movies, TV etc (or this would have posted long ago just for the annoyance factor.) Any suggestions, it is still under warranty.
