The laptop's function keys are used to make the (hardware) change from
internal display to external display (or both). They don't do anything
with resolution.
As long as the output is displaying on the external monitor you should
be able to alter the OS's screen resolution through whatever mechanism
is used normally within that OS. In Windows that would be by
right-clicking on the desktop and accessing Display Properties. Your
situation may be different. If your external display is an LCD you'll
need to run it at the native resolution in order to avoid poor image
quality. If your OS doesn't have adequate drivers for your external
display you may have to download appropriate ones.

I have an old IBM Thinkpad A31p laptop with ATI
Mobility Radeon 7500 graphics chip with 64 meg
display ram. The laptop's 1600x1200 LCD display
has died. I have hooked up an external monitor
(1920x1080). I have been able to reconfigure
Windows XP and Fedora Core Linux to ignore the
dead LCD and use the external monitor at 1920x1080
(which is sharp). But, with eCS 1.2R and 2.0, I
cannot figure out how to do the equivalent.
I believe that the 7500 can do up to:
2048 x 1536 x 16Meg colors
In eCS, using: System Setup: Screen
I have tried 1600x1200 on the 1920x1080 which ends
up with a fuzzy display.
I have tried 1920x1080, but the real screen only
shows a subset (perhaps 1280x960) of the image
(which can be panned) to get to any part of the
full image.
I believe that I am using Snap graphics driver in
eCS 1.2R and have tried both Snap and Panorama in
eCS 2.0.
I understand that there is a choice of graphics
drivers for eCS. Which one should I be using
and how to I configure it?
I am willing to edit some configuration file, but
have no idea what file to mess with.
Doing Fn-F7 does switch between internal LCD,
external monitor, and both; but I see no way to
alter the resolution doing that.
