Re: 2408WFP blackouts out briefly

I first got a 2408wfp new with my XPS630. After about a year, the monitor developed a vertical purple line from top to bottom.

I called tech support who sent a refurb monitor to replace it. The "refurb" was dirty and had scratches on the base. The back of it looked like it had been in a garage for years. Not to mention that there was a dead roach in the bottom of the box.

I called support about the poor condition of the "refurb" and they sent another refurb in its place. The second refurb at least was clean and seemed to work.

I say seemed because now I have the blinking problem that you have all described. I've also noticed that the resolution isn't what the original monitor was. When I look at digital pictures, they look grainy and pixilated.  My 5 year old 20" Ultrasharp looks much better than my 24".

Is there anything I can do? I hate playing roulette with tech support.

Thanks in advance...

Re: 2408WFP blackouts out briefly

Hi Chris,

I haven't been back to this thread in quite some time since I posted my same problem with the 2408 monitor...  I finally gave up with replacement monitors and have come to the conclusion that it is a driver/monitor synch issue because different drivers from Dell, AMD and the default Windows drivers all seem to behave slightly differently... 

I gave up early on the Dell drivers because in addition to blinking, they seemed to hang my computer at boot time and I haven't revisited them since my original purchase over a year ago.  My experience with AMD drivers is that they have a synch issue when coming back from sleep mode (usually 3 or 4 consecutive blinks and then it's fine) and I also experienced an intermittent blinking problem even in the middle of normal usage.  After doing a reinstall of Vista a few months ago I didn't install any separate driver and the default Windows Vista x64 driver which is an ATI Radeon 4800 Series driver V8.501 dated 6/2/2008 seems to only be plagued with the 3-4 blink problem after coming out of sleep mode.  So that's what I'm running with for now.

I appreciate your efforts in trying to help me get this fixed, but am disappointed that Dell/AMD have not come up with a permanent solution.

Re: 2408WFP blackouts out briefly

Hi all,

I had the same blinking 2408WFP issue that many of you are experiencing. I have two 2408WFPs but only one was experiencing this issue, and it was connected via DVI (and using HDMI for a short time). The blinking happened when the monitor was connected to both the DVI and HDMI ports. I upgraded my video card to an ATI 5800 series card which included a DisplayPort connection. Once I connected the offending monitor to the DisplayPort connection, the blinking stopped completely. It has never occured in the last two months when previously it would happen at least a few times a day. Buying a new video card that supports a DisplayPort connection is not really an ideal solution--the cards can be expensive--but it works.

I also have the black-out problems with my 2408 A02 monitor: the unit would occasionally go dark for about 1 sec, and come back with a DVI or HDMI icon on upper-left corner. Here's some things that I notice:

  1. The blackout seems to tend to happen when the monitor has just been powered up. In my case, the blackout usually happens within the first 30 minutes after powering-up
  2. Sometimes it runs well for days without blacking out (or it just happened when I'm not looking), but sometimes it happens a few times in a row in 30 seconds, just as some posts stated before.
  3. I can trigger a black-out that seems to be the same as the random ones by connecting my 3.5in externally powered HDD to the usb port (on my notebook) closest to my notebook's HDMI port. Something caught my attention.

First let's review the mating process of USB ports: first, the outer metal jackets make contact. Second, VCC and ground pins make contact. Third, the pair of data pins make contact. The blackout happens at the first step, so most certainly it's not a software problem. Maybe the microscopic spark caused by mismatching GND levels between my notebook and HDD caused the blackout.

I have no idea whether this is the same blackout problem, though. But, all other monitors seems to do fine when I'm plugging the HDD in.

 

        4. Connecting the monitor to a Displayport on ATI HD5770 seems to work well (since Aug 29, till this post's timestamp and counting).
        5. I have a notebook with HDMI and a desktop, both give me the blackout problems with HDMI or DVI ports.

The blackout problem surely isn't too widespread; I didn't even hear any rumor about this in hardware forums before running into this myself and doing a extensive search. But according to the posts, a replacement often have the same problem. Also, dell tech guys haven't been able to reproduce this problem, according to chris.

 

So sending the monitors back to dell helped. Taking phenomenon 3 listed above into account, I wonder whether EMI susceptibility is the cause.

Re: 2408WFP blackouts out briefly

I must revive this thread much much later, as I just recently started having the flickering problem after switching to an ATI HD 4890 card.  Are they still replacing the monitors for A02s?  I purchased this 2408WFP in December of 2008, and it has worked fine until about 2 months ago when I switched PCs and videocard.

Re: 2408WFP blackouts out briefly

I have had luck using a new graphics card i bought later (crossfire) through the display port. The flickering never seemed to go away for me without going to vga on my old graphics card. I dont not know if they are switching out monitors at all anymore, i never had mine switched.
