SOURCE: Laptop screen has horizontal white lines running across half the screen
Ive encountered laptop screens that are bad, with broken connections or a small carack on the very edge of the screen. I have an old laptop with the very bottom line of pixels dead. But as i push on the edge of the screen they flicker. Try carefully squeezing around the edge of your laptop screen near the lines. Its possible the screen itself is defective and need replacing.

DRIVER FOR LATITUDE

Since the cable isn't the culprit as you determined by moving the cable around. This leads the problem to be either the video card (built in or not) in your PC or the monitor itself. The best way to test this is to switch your monitor with someone else and see which one duplicates the problem. If the monitor is the problem, the good news is that you can find them on sale for cheap online. I found a 19" for $99.99 and am quite happy with it.
The only other thing I'd suggest is updating the drivers for the monitor through Device Manager (right click My Computer>Properties>Hardware>Device Manager). Expand Monitors and Display Adapters. Right click what is displayed and choose Update Driver. This most likely won't be the problem fixer but is worth checking out.
Last question...how old is the monitor ?

You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.
Defective CCFL backlight, it may have the following symptom:
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Had a similar problem, some video "jitter" and then the screen washes out with backlight showing. ONLY HAPPENS when under battery power.
Cause: a recent reinstall of XP SP3 realized a newer video driver, intel integrated 945gm, than was on the Dell support site. This newer driver is problematic.
Download and install the Dell support site's OLDER video driver for the D620. A new battery won't help, only the older driver.
