Only 1 problem

The device has (as others have certainly already written many) some positive sides: The picture quality seems to be good (although I have no way to objectively measure), the Stand is stable and the pivot function is also nice. More important than this, but I find that you can adjust the height (my other monitor stands on a box, so I do not have to constantly look for "down").

The only thing that bothers me are the touch buttons, or really just the far right. This is intended for the on and off, but responds much worse than the others. I do not mean that you aim exactly with your finger, or have to press several times, but that it sometimes does not respond!
I guess that might depend on various environment variables. From the feeling it's more if you have slightly damp hands, or you have previously used short hand cream. Possibly also the electrostatic charge of your body, or the ambient temperature is important ... you do not know exactly ;-)

Anyway, I let the computer to sometimes when I go out briefly, eg if the PC has to be expected any longer, and then I'd like to turn off the monitor - I have but for example, failed yesterday. As I read of the problem by looking in some forums, I assume that this is not a defect.

(My other monitor is actually a 3 years old by LG, which also has touch buttons, but with whom I never had problems.)

Addendum: I have a point deducted because I have minutes-long no longer anbekommen him off, only after many attempts it worked. This naturally leads to high power consumption, because I would normally stop the monitor when the PC anticipates a long time on something ...
I am aware that others have this problem, or may want to turn off the monitor not at all, but since I've read it several times in forums, I can not stand this for one single production failure and therefore relevant.
