Darren,
After trying the steps in other post you could try a PC Restore.
Dell Factory Image Restore The Dell™ Factory Image Restore tool replaces PC Restore. Access it from the F8 boot menu.
Windows PC RESTORE
hennph, Windows 7 PC Restore
These are the steps in performing Windows 7 PC Restore:
Step 1: Backup important files and data
Step 2: Remove non-essential peripherals
Except for the monitor, keyboard and mouse, remove all external peripherals including scanner, printer, modem or network cables, Personal Digital Assistant (PDA), USB flash drive or other external Hard Drive, any other external devices (e.g. USB-attached devices), remove the computer from the docking station if you are using one.
Step 3: Restore the computer's software to original condition
Turn on the computer.
As the computer starts, press <F8> on the keyboard until the Advanced Boot Options menu appears on the screen.
Press the <Down Arrow> on the keyboard to select "Repair Your Computer" on the Advanced Boot Options menu, and press <Enter>.
Specify the language settings that you want, and click Next.
Log in as a user who has administrative credentials, and click OK.
Click Dell Factory Image Restore.
In the Dell Factory Image Restore window, click Next.
Click to select the Yes, reformat hard drive and restore system software to factory condition check box.
Click Next.
The computer is restored to the default factory configuration.
When the restore operation is completed, click Finish to restart the computer. The software is now installed as it was when the computer was first received.
Step 4: Restore your personal files and data from backups
Thank You,

It sounsd like your GPU may be BGA chip and would require a re-flow/re-ball if your laptop shows graphical distortion on both monitors.

However I would first try taking the laptop apart again and double check you have connected everything properly.

try running it in safe mode tap f5 when you see the dell screen. if it boots to safe mode remove the driver for the display adapter in device manager. the dell computer doesn't know what kind of monitor it's plug into. install the soyo monitor driver

Hi

You do not say if your laptop screen is working or not or why you want to use an external monitor.

Assuming the laptop has no fault and boots properly, to send the laptop image to an external monitor, once you have booted into Windows, press and hold the Fn (function) key bottom left of your keyboard, near the Windows Logo key, then simultaneouly press the Function key (above the numbers) with the image of 2 monitors, 1 dark, 1 bright (often the F4, F5 or F6 key).

If the laptop's screen is faulty and the above procedure does not work, there may be damage to the graphics card which will probably require specialist repair.

I hope this helps.

you have two displays enabled in your computer. go into display properties and disable display 2. then you will have the correct screen showing in full

hi bob you should be able to adjust the screen size via the menu on the monitor itself, (Available in Analog mode only) Note When TV signal is input in AV mode ,select “Screen Fit “to adjust vertical position in 0-6 levels. Image Size Note Supplied for the wide models only such as 16:9 or 16:10. You can change the size of the screen displayed on your monitor. PC signals • Auto - The screen is displayed in accordance with the screen aspect ratio of the input signals.• Wide - A full screen is displayed regardless of the screen aspect ratio of the input signals. Note • Signals not available in the standard mode table are not supported.• If the wide screen which is the optimal resolution for the monitor is set on your PC, this function is not performed. AV signals • 4 : 3 - Sets the picture to 4:3 normal mode. • 16 : 9- Sets the picture to 16:9 wide mode. • Screen Fit- Use the function to see the full image without any cutoff when DVI (480p/576p/720p/1080i/1080p) signals are input. Note It can only be selected if an external input is connected to the DVI terminal and the 'PC/AV Mode' is set to 'AV'. • 4 : 3 - Sets the picture to 4:3 normal mode. • Wide-Sets the picture to 16:10 wide mode. • Screen Fit- Use the function to see the full image without any cutoff when DVI (480p/576p/720p/1080i/1080p) signals are input. Note • It can only be selected if an external input is connected to the DVI terminal and the 'PC/AV Mode' is set to 'AV'. • When the panel is of 16:10,the screen size options include “4:3”,”wide “,”Screen fit“.hope this helps

You can adjust the screen resolution to increase the size of the image to fill the screen.
Go to the Control Panel - Display - Settings and adjust the screen resolution to 1280 X 1200 pixels. If this still doesn't fill the screen then increase it further say 1600 X 1200 pixels even higher if necessary.

If you are seeing an shadow image on the LCD and you have video on an external monitor, then the LCD backlight has failed. The LCD will need to be replaced

I googled B130 LCD's and they generally run $125 to $200

Hi...there,
It's seems you got a busted screen panel...

What I've found on two laptops I've worked on in the past two years is that in a case like this, there is a little pin near the power button (or on the strip up near the display) that tells the laptop when the monitor is closed.  If that pin gets stuck, the computer will think it's shut all of the time.  The sensor is only active in normal mode of windows with the drivers installed (if it's in safe mode or VGA mode  the sensor does not work until you raise the resolution.  the sensor doesn't work at all if you boot from a knoppix cd.)

You may be able to just flick the pin and get it unstuck, but in some cases you have to remove it all togther.

To remove it, turn the lapotp off. lean the monitor back as far as it can go (don't force it). You then need to carefuly pry up the strip that the power button is on (ussually there is a space you can pry open on the left or right side of the strip depending on the model laptop; be very careful not to break anything).  You can then pop it out with a small knife or tweesers and clip the strip back down.

If you don't feel comfortable doing this, then find someone who is.

I hope this helps someone.
