evo6tme,

When this occurs, while the monitor is on, disconnect the monitor cable from your video card. The floating Dell red/green/blue/white dialog box should appear on a black background. Do the bright red horizontal lines still show up? If not, the problem lies with the video card driver or the video card.

I have exact the same red lines on my 2407wfp as evo6tme.

As Chris proposed I will disconnect the monitor cable and check if they are still there.
The problem is only that the flashing red lines appear for three or four times and then diasappear until the next time i.e. 1 minute or 10 minutes or 1 hour later.

The other day, I posted in this forum a problem I've got now with dozens (more than 50) stuck pixels on my 2407.  I've also started getting the horizontal lines that the OP wrote about.  One of the first things that the XPS tech spt guy (on the phone) had me do was exactly what ChrisM suggested and, in fact, the lines and stuck pixels went away.  So, the tech spt guy said is most likely was NOT a monitor problem, then he had me start the computer in safe mode and the stuck pixels and lines were still there.  So, he is sending a new video card and hopefully, that will correct the problem.   However, seeing that more people are starting to have this problem, I'm wondering if it really isn't an issue of the nVidia drivers.  I'm running the latest forceware drivers (93.71).  I'm curious if others having this problem are also using these drivers and if that is when the problem started.   ADDED: The local technician called today and will come by this evening to change our my video card (true next-day in-home service).  I will post back after the replacement and let you know if this, indeed, fixes the problem.  If that does not fix it, then I would go with a 'driver' problem and still not a monitor problem (since it doesn't happen when the monitor is disconnected from the computer).

I too have a 2407 with this problem. It is a "Made in Mexico" Rev 03 (October 2006 manufacture). It is connected to a ATI Radeon 9800 via the DVI connector. I will notice a variety of effects: squirming yellowish or reddish lines in white areas and overbright pixels in dark areas. The simplest fix is to 1) cycle the input through all the choices back to DVI-D or 2) turn the monitor off and back on again. Invariably this will clear the problem for the remainder of the session. If I shut the computer off and restart it later it may or may not reoccur.

My thoughts on this are that it "sounds" like a synchronization issue since cycling the monitor forces it to resynchronize. I should add that going into the display control panel applet and changing the refresh frequency will also clear the problem. Once again, this causes a resynchronization of the monitor.

Hope this helps.

just hapened again this time light blue horizontal lines all over the screen, this time i turned the monitor off and back on, i got a mesage saying 'frequancy out of range please select 1910 x 1200 @ 60 hz and restart' . when i checked  all was as set 1910 x 1200 @60hz so i pulled the tower out to check the cables,at that point screen back to normal so i`m hoping its the cable and nothing more serious.

Dell technician came today and replaced my video card and it did fix the stuck pixels and the pixel 'lines' when scrolling.

I think it's a heat problem auf the graphic card.
My ATI x300/x550 128MB is passive cooled with a small heat sink.

Before I got the 2407 the card worked perfect for 1,5 years at 800x600 resolution.
Now with the 2407 and 1920x1200 resoltion it seems that it is overburdened and went too hot after 4 weeks.

An other card of mine a Nvidia 7600GS 256MB passiv works well.

I just don't now if the damage is durable and the card is broken now. ;-(

Hi I bought the 2407 last week from OcUK. I have horizontal yellow lines and sometimes vertical ones. Also notice a lot of pixelisation on the desktop.  I have tried various drivers and it has made no difference so far.  Out of interest my card is an old 7800 and its water cooled.  The card is not overclocked and has never given any trouble before.  I would agree after a refresh the problem goes away for a while. Any comments appreciated Regards Steve
