2408WFP blackouts out briefly

I've been having this very problem ever since I bought it. It blinked when I had Gigabyte 8600 and now with a Gigabyte 4890. The blinks are very random and gets very annoying when surfing the net or playing games. I'm using XP 64 bit. Anyone if there's gonna be fix soon? I've emailed Gigabyte support with this information regarding the Saphire BIOS update but they just said it was the card and just to RMA it. Not happy Jan! Clackers. PS and I should say I'm using DVI and have a RA01 Version monitor

I have the same problem although it happens very rarely. I think it happens when the monitor is turned off or comes back from power save mode. I will have to watch and keep track of when it happens. I am using Vista SP2 with an GeForce 7800 GT Driver version 8.15.11.8618

Dell 2709W

DIV cable supplied with monitor

Firmware A02

Manf Date June 2009 Mexico.

So setting the monitor to run at 60Hz has not fixed the issue.
I have noticed that it almost always happens when I get up from or sit down at my desk.
I thought it was the wires, but I double checked them and it does not appear to be a bad connection.
A colleague suggested it might be EMI that is causing the LCD to lose sync.
It is a really weird issue...

Wanted to report back on this issue:  Contacted Sapphire's tech support and received an updated BIOS for my HD 4890, flashed and haven't seen any blackouts/blinks since.  Thanks to bwesl and others over at tomshardware forums for posting this fix (http://www.tomshardware.com/forum/263520-33-4890-problem-plese-help).

I have purchased 3 of this monitor 2408WFP all running on Dell Latitude E6500 with Nvidia NVS160M video on them.  All of them are experiencing black out issues as described on DVI.  Running Windows XP Pro with latest laptop bios and video drivers.  Monitors are A02 using stock DVI cable, have also tried other spare DVI cables.

Dell please help me fix this issue.

Thanks,

Peter

Unfortunately no, all of our users have laptop computers.  None of them have experienced any issues with the 20" or 22" LCD Ultrasharp panels from Dell using DVI, only the 2408WFP have this problem for us.

We are currently using VGA cable and it is working but we want to use DVI if possible.  I was hoping to get some advice or direction before going through the trouble of returning all 3 LCDs. 

Thanks,

Peter

Do you have a desktop PC to test these on?

Are the users using XP power management or are they just losing the signal while the PC is in use?

I can answer that for me there is no power management involved--- sometimes it will be in the middle of typing an email that it will black out for a second or two.

The Ati users have success by going back to an older video card driver (9.3 to 8.6). have you tried an older nvidia driver?

I have two 2408wfp rev a01 displays on an HP xw4600 (video is Nvidia Quadro FX570) running Linux. One of them is manifesting the same problems I'm seeing described here: display blacks out every so often for 1-2 seconds and then comes back and the little DVI icons comes up like the cable had been unplugged for a second. I've also seen problems when waking these displays up from sleep state: DVI icon comes up for a second but then shows 'entering power save' banner and goes back to sleep. It seems that I can get around this by powercycling the display in question.

I contacted Dell about this problem earlier this year and received two refurbished 2408wfps that had the same problems. After that I returned the refurbs and figured it was a problem with my system: I replaced the video card, flashed the mobo firmware, replaced the DVI cables, changed from Ubuntu 9.04 to Fedora 11, tried various video drivers (free x.org drivers and binary drivers from Nvidia), all to no avail. In light of the other reports on this thread from people running Windows on various different PC systems I'm thinking this is a problem with these displays.

Right now this problem is just annoying and unbecoming for a high-end display product but I'm really worried that at some point it will blink and not come back. Very much appreciate any help or fixes to be had.

Took a gamble and flashed my Gigabyte HD4890 with the Sapphire HD4890 BIOS floating around. Not had a blink since! Would be great to know what Sapphire changed in the BIOS, so everyone could get it fixed.

I have the same issue with my 2709W (A02). Every minute or so, sometimes more often, the display goes black, shows the DVI jack symbol, comes back. The Video card is an HIS ATI 4890 (see below). I also own a Samsung 940BW and a Dell 2001fp. I don't have this issue with the other monitors. I also tried switching cables, and I plugged in an ATI 3450 (same problem).

I got the 2709 exchanged (the previous one also had wandering pixels) but that did not fix it, either.

Some Ati video card users have had success using the Ati Tray Tools
* Install ATI Tray Tools and see if a Hot Key combination will wake it up
* Menu- Hot Keys- Enable Hot Keys (make sure it is checked)
* Menu- Hot Keys- Customize
* Add new Hot Key
* Miscellaneous- Reload display driver
* Assign a Hot Key (I used ALT + T) - Ok
* Now, every time your monitor goes into power save mode you can revive it by pressing ALT + T (you can use any keys you want of course). This also works if you have completely powered off your the monitor
