2407WFP-HC, vertical yellow lines and blue horizontal ones

Question

i think i got an issue about my dell monitor. bought it one week ago. on the second day the monitor showed this little yellow lines. it was shown on websites, on my fotos etc. the blue ones were horizontal across the backgroundpicture. i also have the green shades in some cases and the shadowing/ghosting issue, too. additionally the display is really greenish allover when i start it. after a while it's okay. i use it as a second display for my new aluminium 24' iMac. they are both on the adobe rgb profile, and the dell is on the mac modus (i changed the rgb by myself a bit) this is my unsolved problem: http://www.apfeltalk.de/forum/dell-ultrasharp-2407wfp-t98681.html the 'effect' (yellow and blue lines) came spontaneously and was away when i turned it off and on again. the green-problem at starting stays. what do you think? excuse my poor english. if you didn't understand what i meant, please ask again, i will do my best. thanks for your support!

rotkaetzchen, Please test using both the VGA and the DVI. Any difference?

hi chris,
would do that of course, but my imac doesn't have a vga and i don't like to pay once more for an apple adapter which i don't like to use in the future, cause the dvi signal is the better one. don't know if it makes sense to convert a digital input to an analog and this again back to a digital image?

I do have the exact same issue here. The HC is from a Czech production.
Switching off and on again will help but still this annoying. Seems like the display is getting problems during warm-up.

I will try to test with VGA, but this will take some time.

Yap, TangoSWillaims, mine is from Czech Republik, too. Please post something if you've got experiences with VGA. maybe it's a dvi-cable issue or something. how often did this happen to your display? is it regularly? i will note it, when it happens again, too, so we maybe have a little summary of the problem.

I also seem to have this problem. My screen is a CZ product too. I've put some pictures in the following thread:-   http://www.dellcommunity.com/supportforums/board/message?board.id=dim_monitor&message.id=83081   Should i do the same and private message you Chris with the details?

DELL-Chris M · Answer

fallbayuk, Nope. Just hang tight and check this thread for any updates.

DELL-Chris M · Answer

All, Please provide the video card, driver version, and video acceleration settings.

hi chris! as ia m using an apple (new 24" aluminium g5) it's not possible to adjust any settings of the graphic/videocard. here are the specs out of the system profiler:

ATI Radeon HD 2600 Pro:

Chipsatz-Modell: ATI,RadeonHD2600
Typ: Monitor
Bus: PCIe
PCIe-Lane-Breite: x16
VRAM (gesamt): 256 MB
Hersteller: ATI (0x1002)
Geräte-ID: 0x9583
Versions-ID: 0x0000
ROM-Version: 113-B2250F-212
EFI-Treiberversion: 01.00.212

i asked some people, they told me, it's only possible to pimp or change settings of the card, if bootcamp is installed. but i don't need windows, so i can only tell you that i am using the apple specific settings. and i don't know them. sorry :(

Video Card: Radoen 9800 Pro Driver: Catalyst 7.9 Video acceleration: FULL and also the next step down. Have not tested any other settings.

fallbayuk · Answer

Its doing it on every initial power up now, really starting to bug me!

DELL-Chris M · Answer

fallbayuk, Get an exchange and see if the replacement does the same thing. If it does, the monitors are not at fault. The issue is with your PC or the video card. Dell phone numbers by country

I put this in another thread but this thread seems to be the correct one so I will put it here too.

Hope that is OK.

I am having a similar problem with a Dell UltraSharp 2407WFP-HC 24 bought in UK.

I had been running it for about a month when problems started to develop:

- Flickering thin horizontal lines
- Corruption in pixels at different areas: Flashing pixels, pixels with wrong color.
- Corruption of files in yellowish areas extending to the right after Icons and after text. Sort of as diffuse thick horizontal yellowish lines.
- Vertical lines as if the colors were poured out.

A simple refresh - changing to another resolution for a few seconds fixes the problems for some time - 15 minutes, an hour or two.

The problem then reappears after this time.

I am using a geforce 8600 GTS driver card and updated its drivers. I am using DVI and the DVI cable supplied with the monitor. Updating the drivers did not resolve the problem. I am now going to try another graphics card but the chances are high that there is something wrong with the screen. So what to do? The screen is otherwise wonderful.
