I just got a Brand new Dell p2418ht and am using it on windows 10 If I reboot my computer the touch capabilities work for the first five minutes and then it stops responding to a touch. I tried downloading the dell software, but no help there.
Edit: so it also works again after the computer 'wakes' up from sleep mode.
