U3014, Flickering lines

Hi dandreid,

Dell U3014 Monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. Here are the steps:

• Turn Off both your computer and the monitor.
• Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove all video cables from the back of computer.
• Turn on the monitor.
• The floating dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains white.
• Depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
  
  
  
  
  
  
  
  
  
  
  
• This box also appears during normal system operation if the video cable becomes disconnected or damaged.
• Turn Off your monitor and reconnect the video cable; then turn On both your computer and the monitor.

If your monitor screen remains blank after you use the previous procedure, check your video controller and computer, because your monitor is functioning properly.

You may also perform Built-in Diagnostics to determine if the screen abnormality you are experiencing is an inherent problem with your monitor, or with your computer and video card. Here are the steps:

• Ensure that the screen is clean (no dust particles on the surface of the screen).
• Unplug the video cable(s) from the back of the computer or monitor. The monitor then goes into the self-test mode.
• Press and hold the 'Button 1' and 'Button 4' on the front panel simultaneously for 2 seconds. A gray screen appears.
• Carefully inspect the screen for abnormalities.
• Press the 'Button 4' on the front panel again. The color of the screen changes to red.
• Inspect the display for any abnormalities.
• Repeat steps 5 and 6 to inspect the display in gray, red, green, blue, black, white, and text screens.
• The test is complete when the white screen appears. To exit, press the 'Button 4' again.

Note: You can run the built-in diagnostics only when the video cable is unplugged and the monitor is in 'self-test mode'.

If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the monitor is functioning properly. Check the video card and computer.

Hope this helps. Please reply if you have any questions.

dandreid,

Are you using the DVD-D Dual Link cable that shipped with the U3014? List all of the available ports on your EVGA GeForce GTX 285.

Hi dandreid,

Thank you for sharing the information.

I recommend that you try connecting the monitor to another system to replicate the issue. You may also try changing the display cables with known good one.

Also, reset the monitor to factory defaults once. Here are the steps:

• Bring up the OSD Menu.
• Use the buttons on the monitor panel to highlight 'Other Settings'.
• Select the 'Factory Reset' option and restore the monitor settings to factory defaults.

You may also refer to the manual of the monitor from the link http://bit.ly/14rHLaU.

Please reply with findings.

@DELL-Saharsh K: I'll try to find another system and I'll buy another cable.

I did a factory reset this morning. ( it's almost 6 PM now )

Right now the OSD Menu doesn't show up. :) and I still have to long-press the power button to close the monitor.

@ DELL-Chris M: Yes, I'm using the DVD-D Dual Link cable from the U3014.

The ports from my EVGA GeForce GTX 285 are: two dual-link DVI and one HDTV

I tried on both DVI connectors.

Thank you.

Hello,

I have new information about this problem.

When I start the monitor and the PC...the problem with the lines appears...after a few minutes it stops...everything is ok.

When I turn off the monitor and turn it back on...the problem re-appears...and again, after a few minutes it stops.

Any ideas?

Regards,

Andrei

* Open the DDM (Dell Display Manager)
* Click Auto Mode. This should open the Auto Mode tab
* For all listings, change them to Standard

Retest for lines.

Hello ,

I have the same monitor for 4 weeks and experiencing exactly the same issues as Dandreid. strange lines after monitor startup (few minutes), long pressing ON/off button, OSD issues... and you should definitely turn off the video movie enhancements by default at factory. That's more of a bad joke.

just to add "I've had it at studio for 4 weeks and took it home now ... 2 different computers, same systems windows7 64bit, sadly same problems)

Hello, no change ... lines still there,

Hey Guys,

Just got my new u3014 today and experiencing the exact same problems as these two users.  It's eerie as the symptoms are exactly the same. 

1. Flickering lines as in the Dried video(thanks for that btw)

2. OSD menu acts erratically, sometimes freezes, mostly will not respond to button press

3. Often will lose signal and have to power cycle to get monitor to respond.

I have a

Win 8, 64 bit

4 gb ram

Nvidia 660TI 

Tried both the Displayport cable and the Dual DVI that came with the monitor. 

Is this def a hardware issue?  What steps should I take? 

Charles

One last bit is my old monitor was a Dell 2405FPW, which ran perfectly. None of these issues. It still runs fine, I just wanted a bigger monitor.
