Help with laptop video

[Zandorph]

So, I just loaded D2 onto my Acer laptop with a ATI Mobility Radeon X1400 video in it.

When I play, the screen is very small (about 25% of the actual laptop screen) and the rest of the screen is blank.

Is there any way to change this, or am I screwed for playing it on this computer.

Any help would be greatly appreciated, thank you in advance.:D

Also, I am running XP, sorry about not saying that sooner.

I'm running D2 on my Dell laptop and have no problems running in full screen.

Did you adjust your laptop settings or in game options?

I normally run 1280 X 800 and mine switches when D2 runs. Not sure the size but it's full screen.

My laptop came with Vista btw.

I cannot find any option ingame to adjust the res, when I run the test it gives me 2 options but when I choose the 3d one, I just get a blank screen, so I am stuck with 2d. I see no option ingame to adjust the resolution.
