Problem with external monitor on new laptop - worked fine on old laptop VBM 09-14-2005

I have been using a 17" Envision LCD monitor hooked up to my previous laptop
(Thinkpad) for years. I just got a new laptop (Toshiba M55) and it is
acting oddly. When
I first fire up the computer, it will show the Windows XP screen on the
Envision (and not on the laptop screen), but when it gets to the blue
"Welcome" screen, it goes blank on the Envision and shows up on the laptop
screen. Nothing further shows up on the Envision after that.

What is going on?

Do I need to get the Envision driver for XP? I have never needed to add any
drivers to XP so far.

Not likely.

I don't know which graphics card you have on your laptop nor how it
behaves. Typically, one would have a choice of the laptop monitor,
external monitor, clone mode (i.e. identical display on both), or
extended mode (two monitors acting as a single logical unit). And,
although one has access to monitor configuration from the Display
Properties screen, settings made here do not always work in perfect
harmony with settings made via the graphics controller.

Have you made the proper settings for your expectations?

In the Display Properties, yes, but I don't know how to check anything about
the graphic card settings.

I did find that when I choose to extend to the external monitor, it will do
that (albeit with a very pixelated picture, but that may be just the
resolution settings, hopefully), but it will not show anything on the
external when I want them to both be cloned.

Two possible reasons for this spring to mind...

Have you set the laptop to give an output at its VGA out (Function + F7 or
F5 etc - the key with pics of two monitors or LCD/Mon on it)...?

Second possibilty is that your new laptop has a higher resolution than the
old one and the monitor cannot handle this... if so set laptop to lower
resolution display.

I tried the Function-F5 and it showed the three options, with only the LCD
highlighted (on the far left). I tried clicking on the middle one, which
shows two, but it won't change. I am not sure if it matters, but the
external is an LCD as well, not CRT.
