I have tried searching for a driver that works. This monitor was included with a desktop from dell. It's fine until I start scrolling, then it really hesitates. I even tried messing with the setting to no avail (contrast, brightness, etc...) couldn't find a control for refresh rate.

Re: screen refresh is "jerky" when scrolling
The refresh rate for LCDs is 60 MHZ, your problem is very likly a video card driver issue. Unless you've changed the cards you should be able to download the correct driver direct from support.dell.com.

My Dell Inspiron 530 (running Vista) started having video problems. (After working fine for months). It would boot and let me log in, and would display the desktop for a moment, then the desktop would refresh, the screen would go black, and my Viewsonic VG 150 LCD monitor would display an error "Out of Range".
"Out of Range" error means "I am getting a signal, but it's not a signal that I recognize so I can't display the image".
It would boot correctly in Safe Mode, and also in 640*480 resolution. But it would not work in 1024*768 resolution (the native resolution of this LCD).
I noticed that Microsoft Update had, the night before, installed an Optional update to the Intel onboard video controller driver. The driver was dated Feb 2008 and that is the latest from Intel, so I don't understand why it installed a new update in April 2009 (?).
I ran the Dell diagnostics on the video hardware and I did notice that in one sequence of about 15 screens that flashed quickly, two of them displayed the Out of Range error. So clearly the Intel video hardware is able to generate a mode that this monitor cannot handle.
My best guess is that something about the automatic Update of the driver is what broke this installation.
I removed the Intel driver (in Device Manager.. Display Adapters), so Vista fell back to its generic video driver, and the problem went away... I can select 1024*768 resolution and it boots fine.
I haven't yet attempted to reinstall the Intel driver (I'm just happy to have it working again).
Could be your refresh rate. Try the following: * change your monitors refresh rate to higher availible. * rt click on desktop
then on properties and then display setting and then advance and then
click on monitor tab and choose the highest availible and then click ok.
Would also attempt to move the screen forward and back to see if you have a pinched cable.
Also attempt to connect to an external monitor to see if it is your laptop monitor or the video card causing the problem.
Have you tried to increase the screen's refresh rate? If you see some sort of blurring horizontal line that scrolls upwards, most of the time is that screen's refresh rate in your Display Settings are too low.
Check that you have installed the correct driver for your model video card and the correct OS version.
To check that the video card and driver is working, you may have to boot up in Safe Mode, go to Control Paned - System - Click on Hardware Tab - Click on Device Manager button - scroll down the list and if you see a yellow ? against the video then there is a problem with the video driver.
The problem could be that the refresh rate for the monitor is too high for the monitor to handle.
Boot up your computer and press F8 and then run in Safe Mode, go to Control Panel - Display - click on Settings Tab - click on Advance the Monitor Tab and change the refresh rate to 75Hz or lower.
the problem can be from the video card or from the monitor.for the monitor go to the officila dell site..there you can find all the drivers you need..and for the video card instal a new propper driver.. if all this doesnt work..well contact a specialized Dell service.. bye
Your screen refresh rate may be too high for the monitor or one of the parts might be incompatible with windows try lowering your screen refresh rate. Or checking windows for a compatible driver for the chip or monitor.
