U2713HM "Lines" on display with flickering

Hi dcu4m,

Please try the following steps:

Steps to perform SELF-TEST:

Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. Run the monitor self-test by performing the following 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. Also, depending upon the selected input, one of the dialog boxes 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, perform Built-in Diagnostics to check the hardware functionality of the monitor.

Steps to perform Built-in Diagnostics:

Your monitor has a built-in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent problem with your monitor, or with your computer and video card.

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

To run the built-in diagnostics: 

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

The test is complete when the white screen appears. To exit, press Button 4 again.

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

If the lines still appears on the screen on the aforementioned steps please try resetting the monitor back to factory settings as it can be an issue with the monitor hardware.

Steps to perform Factory Reset:

Reset all OSD settings to the factory preset values. Perform the following steps to reset the monitor settings:

• Press the Menu button on the monitor to get the OSD Menu displayed on the screen.
• Press the down arrow button to scroll to the Other Settings option.
• Press the Selection button. Now press the down arrow button and select the Factory Reset option.
• Press the Selection button to reset the monitor settings.

I have exactly the same problem, the screen also keeps some images, I turned it off, unplugged everything, then 10min I turned it on, the images was still there like burned.

OSD is affected too, factory reset.... I tried everything, the screen is just dead.

Hi romaindv,

If you have tried the aforementioned steps, then it indicates that the monitor has hardware failure.

I have added you as a friend. Please accept my friend request by clicking on my name highlighted in blue and then click on “Friends” tab at the top and then click on “Request to Review” and finally click on “Accept” button. I am sending you a private message as well. Click on “Inbox” to respond to the message and provide required details.

My U2713HM monitor apparently has a hardware failure as well. I went through the steps you mentioned and there are several flickering lines horizontally across the grey test screen. Please help/advise!

Thanks,

Ryan.

My Dell U2713H also flicker horizontal lines some time, but when I connect to another PC that is no this issue.

So, I clean the original PC, use sand rubber to polish golden fingers of 2 old DDR2 Ram (5 years old)and display card(2 years old). It seem LCD flickering lines solved. Thus, I think bad contact old rams can cause display flickering.
