I just picked up a Dell C400 laptop from ebay that has a problem with screen resolution. The laptop will only boot into its lowest resolution, therefore only the central part of the screen is used. It is not an OS problem as the tiny resolution starts at bootup and continues whether in the boot screen, bios screen, DOS or XP. I tried re-installing the video drivers while in XP and on reboot the screen goes blank and remains blank. It is obviously a MB problem but short of replacing the whole thing, is there something else I can do to remedy the problem? Thanks.

If your resolution is making issues..it can be changed from the video settings ..usually when you install the video driver and restart ..the computer wil select the proper screen resolution right he way ..but if you do not have the driver installed this can be a problem ...so first make sure you have the driver ..and run it again ...This may solve the issue . If you still want to try another resolution for some reason ..make sure the driver is installed ...and go to control panel ..select display ..and in there select display settings ..and change the resolution and apply .. make sure you select one on your taste ..but remember that usually the one selected by the driver automatically it is the best one ..if the one selected it is causing the image being hard to see...than you select a smaller resolution ..and the objects will be larger.... Ex for a 17 '' display ...the best will be 1024 on 768 ... Good luck ! By the way ..if you have a icon on the tray (notification area) with the display ..it can be changed from there too ...just click on it ...select the display resolution ..and change the values ..
Please try to:
check the highest resolution of the external screen
then set the resolution of your laptop base on the capacity of the external screen
right click on the blank section of your screen then click properties
then go to settings
choose one like 1024 x 768
plug the external monitor
make sure the cable is in proper position
then power on the monitor

First of all, by the sounds of it, it is booting to a very low resolution. ;)
Assuming that you run Windows, right click your desktop and go into either preferences or display settings. In one of those tabs, you'll be able to adjust your screen resolution. Usually the maximum setting it gives you is what your monitor is designed for. If not, just play around with the settings until you get the right resolution. If you screw something up, it's not a big deal; just don't do anything for a bit and it'll revert to the previous setting.
I hope this helps!
It can depend on what kind of flickering you are seeing. A very very fast one, that shows more obvious if you look to the side of your screen (instead of directly at it as normal), means your screens 'refresh rate' is most likely wrong.
That's the most likely problem you have, as the inverter will usualy only make a screen flash, not flicker, though they don't usually flash too much before the bulb or inverter can't take the strain and breaks properly.
Sometimes a screens circuit can go slightly faulty (very rare) and cause a slight change in its refresh cycle, and that can cause a high speed flickering too, usually accompanied with a very slight blurring of any images.
The standard setting for a C400 is 1024 x 768 resolution at 60 Hertz, so check your display properties to see that's not been accidentally changed.

Boot into Safe Mode and change the video resolution to the lowest resolution supported. Reboot the machine normally. The problem should have disappeared. From here you can readjust your display resolution to any higher resolution supported by the system if you wish.
I have seen this problem before, after booting to the external monitor go into the display settings and try setting the resolution to 1024 X 768 and the color settng to 16 bit or preferably 32 bit. If you can do this, then shut down the laptop remove the external monitor and try booting on the LCD display. BPCS
