U2414H touch buttons stop working after some time

Question

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. Product Specific Problems

"Cannot adjust the monitor with the buttons on the side panel. OSD does not appear on the screen"

• Turn Off the monitor, unplug the power cord, plug it back, and then turn On the monitor.
• Check whether the OSD menu is locked. If yes, press and hold the button above the Power button for 10 seconds to unlock (for more information, see Lock"

Same problem here: I'm leaving the monitor ON or OFF for several hours and then the touch controls stop responding. Yes, this happens even if the monitor is powered ON. To be able to turn it OFF, I'm unplugging it, leave it like that for 20-30s, plug it in again, it automatically gets powered ON and then the controls start working again and I can turn it OFF.

Does anybody know how to fix this issue?

My videocard is: Gainward GTX760 (looks like nVidia reference design) connected to the monitor using an HDMI cable.

Get those monitors exchanged. * Go back to the top of this Monitor Forum* Open 'FAQ Monitor'* Open 'Monitor warranties and instructions'

the problem is, we have 4 of them here and they ALL do this. there's nothing wrong with them otherwise and exchanging them just to get the same 'results' would be a big hassle.

DELL-Chris M · Answer

There will not be any in home hot fix or anything like this. Exchange one of them and see if the replacement has the same serial and revision, and does it have the same issue.

I have the same problem. I bought this monitor a few days ago and the problem is that after a couple of hours of operation the touch buttons do not respond. I can not turn off or turn on the monitor. Menu buttons also do not respond to touch. I must remove the power cord and reconnect it for buttons to work again. I will replace it.

I have exchanged mine, REV A00 from June 2014, for another one from June 2014 with a different revision, A01. Unfortunately the problem still shows up. At the office we have 4 more, but I only had time to test a single one and the end result is the same. That one is A00 from December 2013.

Any suggestions?

Probably more people would complain if they'd turn on/off their monitor instead of leaving it in standby mode.

DELL-Chris M · Answer

I can only speak to the Americas stock. Here, the U2414H A01 released on May 18, 2014 corrected the button issue. But you mentioned your A01 from June 2014 still has the issue. All you can do is keep getting exchanges.

I tried to email the local RMA service again about the issue but it seems that my personal email address has been added to their blacklist. Probably they didn't like that I questioned the fact that the monitor I received from RMA didn't look like it was a new one. That's because the monitor didn't come sealed in a retail box, neither packed in something that made it look like it was brand new. They just replied that they used the monitor to test the issue, and then it seems I got my email on their blacklist:

Delivery to the following recipient failed permanently:
dell.rma@lasting.ro

Technical details of permanent failure:

Google tried to deliver your message, but it was rejected by the server for the recipient domain lasting.ro by mailserver.lasting.ro. [193.231.122.200].

The error that the other server returned was:
550 5.7.1 Recipient not authorized, your IP has been found on a block list

So I emailed them from my work email address and it looks like they are more cooperative now. I'm supposed to send them the monitor S/N so they can order a new one. Although they were professional up to the moment I questioned them, I still find blacklisting a client's email address inappropriate for such a big company.

I have never heard of us blacklisting an email address.

I have the same issue. Since this is for our company. I was able to try another u2414h the same day and I experienced the same problem. I noticed this doesn't happen for any of our official dell computers that we distribute to our employees and we have deployed over 50 of the u2414h but I am using this on my own personal built computer and two monitors in a row with the same issue seems weird and not a fault of the monitor itself.

The video card I am using is the Gigabyte windforce radeon r-290 with an HDMI cable.

denzuck · Answer

This doesn't look like a hardware issue per se since buttons work perfectly right after unplugging/plugging monitor back in. It's rather a strange combination of monitor drivers and certain (seems the issue is wide spread with non built in video cards) video cards/drivers. It's puzzling why Dell's suggestion here is to keep exchanging (just to get the same issue).

DELL-Chris M · Answer

The displays team has dictated that the monitors should be exchanged.

luci.pacurar · Answer

I got my third one for more than a month and the problem is still there, but it doesn't happen that often. I will probably not exchange it anymore before a new revision shows up.

PS: The RMA service said that they didn't block my email address. Anyway, they were professional.

Do you know which revisions have fixed this issue? I want to replace it and make sure it works this time.
