Built-in LCD screen resolutions on 400MHz G3 laptop, in 2 screen mode

We  just bought the 400MHz G3 laptop. We want to run it connected to a second screen
(at 640 x480 resolution - the only resolution supported by the second screen output, I believe).
But, we also want to maintain the resolution of the built-in monitor at 640x480 at the
same time.

When the laptop is not connected to an external monitor, it allows you to select from
any of three resolutions - 640x480, 1024x768 or 832xwhatever.

When the computer is connected to an external monitor, it allows the built-in screen to
display in 1024x768 only. This is a problem for our purposes.

Does anyone know of a way to connect this machine to an external monitor at 640x480
while at the same time setting the built-in screen to 640x480.

Any help would be very much appreciated.

I also have a PB 400 and have run into the same prolem. Aparrently its a bug and im doing some research to find a workaround. Connecting an external monitor to the PB should also lower your built in screen colors to Thousands instead of Millions. Ill get back to you when i find out more.

from what I have read, when connecting to an external monitor, the PB screen resolution is unchangeable from the default setting you mentioned.

Screen rez may be unchangeable but screen colors should certainly be able to hit millions. Especially with 8 mb of VRAM. Please point us to that documentation.
