17" Flat Panel Monitor flickers
The only resolution that is acceptable is 1024X768. As soon as we increase it to 1248X1024 is has a flickering throughout the screen. And lower resolutions don't appear very good in quality. Any suggestions for possible fixes. Any known quality issues with different resolutions?

Thank you for using the DellTalk Forum.
You can try changing the refresh rate to stop the flickering. To change the refresh rate you can go in the Display properties in the control panel. You then can click Settings | Advanced | Adapter and you should then see where to change the refresh rate. Try setting it to 75 hz to see if that will resolve the flickering.

I'm running a dell 1800fp (18" Ultra Sharp) using a Radeon 7500 digital/analog video card. When I use the digital cable, the monitor looks great for about 30 minutes, then begins blacking out. It's not a flicker or occasional blur (I get that too), but it is a complete black-out for about 1-2 seconds. I've checked my cables and card seating. I've reinstalled both the dell monitor drivers and also the video card drivers, but to no avail.
Using the analog cables, their is no problem with the black-outs, but the quality is so-so (bad ghosting of images). I am running it with the factory recommended settings (1280x1024 @ 60/65htz) on a dell 8250.
My best guess is a faulty video card (which I will RMA this week) except for one thing... Once the black-outs start, they are frequent (maybe once or twice a minute for a couple seconds). But if I turn the power off on the monitor, then back on, the black-outs stop; for a while.
Any advice is appreciated!

Did you correct your problem? I am having the same issue with 3 machines

DudeFixMyMonitor,
Thank you for using the Dell Community Forum.
Try just using either Digital or Analog only. If you are wanting to use the Digital you can unplug the Analog cable to see if that will resolve the issue you are having with the monitor.

I tried changing Refresh Rates, frequencys, resolutions, high color, 16 bit, 32 bit, hardware acceleration set to none, New updated Radeon/Driver Control Panel, default monitor, plug&Play monitor, nothing worked. Same symptom, blackouts, then finally the mouse becomes frozen.
So, removed Radeon 7500 card, let it find it's internal intel graphics card, guess what?! Same problem. Tried all the other scenarios mentioned above. I have tried differenct monitors, cables, I even thought it might be a power flux and hooked them into a surge protector/UPS.
This is happening with 1700FP and 1900FP, running with Optiplex GX260, running Win2000.
Any ideas?

I have a similar problem, though I'm not using a dell monitor or a dell pc. I'm posting here since this was the only thread I'd found on the Net about this situation.
I'm using a hercules 3d prophet II gts pro with an analogue video cable.
I bought this new cornea CT1700 flatpanel and it worked fine the first two days. Since then I was getting black outs. The display dissapeared, came back..and so on.
So I went to the store, explained the problem and got another one.
The new one worked fine for a day...then,same problem.
I'm also working with win2000.
I've changed the video drivers, but it's still the same.
I've even reinstalled windows 2000, and used a default graphics card driver, but I still get the same problem.
So Cass7 I was wondering if your problem was solved.

I have the exact same problem. This is a very annoying problem for an otherwise great monitor. The screen randomly goes blank for 1-2 secs and comes back on (this is not a "flicker"). This comes and goes. I have found that when I am scrolling a long page of plain text very fast with the roller wheel of the mouse, I can usually force the "black outs" to occur. I have tried many different display settings and updated all drivers with no luck. As a side note my father just bought a gateway with the exact same problem on a CRT monitor. An updated driver cured his. Maybe this is a driver issue?????
Dell Please Help!
I am running an 1800FP w/ Sapphire ATI Radeon 9000 using DVI.

I called Dell a few days ago and they shipped a replacement (refurbished) monitor, which arrived today.
Surprise, it has the same problem! I'm really not sure what to do at this point-- no one at Dell has any clue as to what the real problem is, and I'd rather not have to keep exchanging monitors.
Mods, any suggestions?

My Moniter blacks out too! And it's driving me crazy. I have a Dell flat panel 17' and it just started doing this. Machine is about a year old. I have tried everything to get it to stop but nothing seems to help. Blacks out about every 1/2 hour for 1 or 2 seconds. It also blacks out briefly when loading up right after I turn it on.
Help!
