Dell C400 Resolution Problem

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?

    After I posted I had the "brilliant" idea of checking the video section in the bios. Sure enough there was an option that allows expansion of video. Problem fixed.
    I feel foolish.
    Thanks for the response.

    Sorry, I will be more specific. Go into PAGE 4 of 7 and go down to Video Expansion in the BIOS. If it is Disabled, Make it Enabled. Good luck

Change my screen revolution

If your resolution is making 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 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 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 can be changed from there too ...just click on it the display resolution ..and change the values ..

Dell b130 laptop boots to very high resolution causing the image to be compressed to the left side of the screen

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!

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.

It is when you see this BIOS or Dell logo Screen that you Need to:
  • PRESS F8
  • Press F8
  • Press F8, again, and again right when your computer turns on.
Then You should be brought to the Window that allows you to boot into SAFE MODE, DO NoT PICK SAFE MODE.

Pick: ------------ENABLE VGA (basically safe mode) Only!.

Once booted, log in and change the resolution to let's say 800x600,
then restart your computer normally.

You should then be able run windows normally, (Without F8 Key) where you can then change the resolution to what you want.

IMPORTANT! Remember this, if you set your display to a resolution that it Does Not

support, and the screen goes blank. DO Not Turn off your computer: ALL YOU DO IS PRESS

the (Esc) ESCAPE Key within 15 Seconds and your monitor's resolution will be set to it's

previous state again.

Dell C400 will not boot using LCD screen when cold

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
