I have a Dell Inspiron 15 5559 with the touch screen. A few weeks ago, it started up with the annoying "ghost touch" phenomenon, making the machine nearly unusable. There is no physical damage to the screen. I have spent more time than I care to admit Googling solutions. The most common answer I find is to disable it through Device Manager. Here's the history of my attempts to solve this.

 

  1. At first, the "HID Compliant Touch Screen" did not show up in Device Manager.
  2. I had to select "show hidden devices" to find it.
  3. Once I found it, I right clicked "Disable Device" and confirmed the command.
  4. Everything was good for a day.
  5. When I brought the PC back from sleep, the ghost touches were back.
  6. Repeat steps 1 through 3.
  7. Solved the problem for about 10 minutes. Then ghost touches returned,

 

I've been doing the "disable device" dance now for about three weeks, and I'm growing very tired of it. Someone please tell me that there is a way to make this problem go away for good! It has taken me abut 30 minutes to write this post.

Since you have found it in Device manager, have you tried uninstalling the drivers ?  This might work although, if it is like mice, keyboards and USB drivers, it might just re-install itself as and when you re-boot. If that fails, and I suspect it will, I think you arre going to have to modify the registry entries for the touch screen. And that is an area where I have no experience at all.

Something, and that something really shouldn't be Windows itself, is re-enabling the device.  I've dealt with computers with touch screens whose digitizers have gone wonky and to a one disabling the HID compliant touchscreen permanently disables it.

 

The fact that this came back after waking up from sleep makes me very, very suspicious of some sort of infection, but it's purely a suspicion.  Digitizers do go wonky, but devices virtually never re-enable themselves after being manually disabled, and that should be across all future shutdown/startup, restart, sleep, or hibernate cycles.

 

You could also try following the instructions for 


to see if something is corrupted in the OS first.  If you have a spare monitor around somewhere with a connection you could use (e.g. HDMI or VGA) to set it up as a secondary screen "for the duration of diagnostics" and using only the second screen it might give you some respite from the insanity until you can figure out how to get rid of it entirely.

Yes, I did try uninstalling, but they mysteriously come back after a few minutes.

 

One detail I failed to mention in the O.P. is that this behavior started a couple of weeks after I did a fresh install of Windows 10 on a new hard drive. I was not able to find the correct drivers on the Dell site, yet Device manager says the correct drivers are installed.
