DVI Interference on my 2005FPW

jdalton007,

Considering all that you have done already in troubleshooting this problem, it would seem that the problem lies within the monitor itself.  You will need to contact the Dell Techies to insure that your troubleshooting is complete and possibly have the monitor replaced.

Jdalton did you get this fixed? I am having the exact same problem, got my 2005fpw Monday. Lines are only on the left side and they go away when using VGA cable. Please respond.

No, I never got it fixed. But someone else emailed me with the same problem and he found a fix that may work for you. I just had mine replaced before he sent me this otherwise I would have tried it. Good luck. Let me know if it works.

Hi again,

Thanks for your reply.

Since emailing you, I was able to find some additional information. It seems
that in some monitors, the DVI input is too peaky about the pixel clock
frequency. According to Dell, the pixel clock should be 119MHz when in DVI,
however some monitors produce these scrolling lines at this frequency.
However, they stop doing it if you raise the frequency to 146.25MHz. This is
what I did using the NVIDIA drivers (advanced timing button) and it solved
my problem.

However, this doesn't mean that there isn't something wrong with the
display.

BTW, which revision is your new monitor?

Regards,

Theo

Hmm, now do I change the option or send the monitor back for a replacement?

Another thing, when you got yours replaced you didn't have the scrolling lines problem?

Well seeing as you, I, and this other person are the only 3 people in the world that I know of with this problem, its probably safe to say that your new one won't have this issue. Did changing the pixel clock in the driver actually fix your problem? I never actually got to try it.

I just put it on CVT and it fixed it. Now, do I send it back still or keep it with the fix?

My option in the drivers was set on CVT-Reduced Blanking at 119 MHz so I changed it to CVT standard at 146 MHz and the lines went away. What is Reduced Blanking and am I loosing performance doing this?

The only way to change the timing is to pick options and im not sure which one to use.
These are the options:
Coordinated Video Timing (CVT)
Discreet Monitor Timing (DMT)
They both change the timing to 146.25 MHZ but they change different options so im not sure which one I need to use.

Count me in as one having the same problem. I've tried to connect this monitor on a Dell Dimension 9100 and a Dell Dimension 4700. One has an ATI X300SE and one has an nVidia GeForce 6600GT video card. Same wavy lines to the left of the screen when connected via DVI. Does not appear when connected via VGA port.

Let me guess, July AO2? Everyone with this problem needs to call Dell and let them know. I have had 3 monitor replacements and its on every one of them.

Yeah mine was a July A02. Interesting.

Mine is also Rev A02 but Mfg date of May 2005. I've sent an e-mail with Dell Support.

My problem is finally resolved. Indeed, it was a monitor problem.

First, they sent me a replacement monitor. Same Rev A02, same May 2005 manufacturing date as my original monitor. Same problem but to a lesser degree (smaller width of the affected area on the left side of the screen, and finer wavy lines). I told Dell Support that the monitor is still bad.

Their next step was to send a local tech rep to check my video card. I reiterated to Dell Support that the problem can't possibly be the video card since I tried another video card on another Dell PC but the problem remains consistent.

So Dell Support sent a third replacement monitor and this time, the wavy lines are gone. Yes, even at the DVI pixel clock of 119 Mhz, as per monitor specs. This monitor is still Rev A02 but the manufacturing date is now July 2005.

So I guess we're all just victims of getting a defective product since the others (majority?) don't seem to have this problem. What's surprising to me is that they send a replacement that is still bad, as if the product wasn't tested to ensure that it does not have any defects.

For those of you out there having the same problem, have Dell Support keep trying to send you the replacement monitor until you get a good one.

I also have the same exact problem with my monitor. I just got a replacement sent to me, and strangely it has the same defect (replacement was October REV A02, my old one was July A02). Looks like I will have to keep trying.
