After some time (few hours or next day maximum) menu touch buttons stop working. I have to unplug the power cord and connect it again to regain touch buttons to work.I found this article in the user manual under Product Specific Problems sections but this is quite too often.
Monitor is U2414H, Rev A01 from May 2014.
