Thank you for replying and extended kudos for affording myself and this forum, your untiring contributions.
Note that previously I errored by referring to my missing console as a 'NVIDIA' console, as in fact it's the "Intel Graphics Media Accelerator Driver for Mobile" console in that I finally re-located my screenshots of that console's settings (note it afforded "1024x728").
FWIW, my notes tell me the console stems from 'Intel GMA 950 driver for Mobile', ie; the graphics engine built into the AOA150's chipset (on the motherboard), so apparently something's preventing that engine (and the Fn+F hotkey) from functioning.
In my search for why the 'GMA 950' engine seems crippled, so far I notice in the msconfig's 'services' tab, the following potentially relative 'stopped' services; application mgmt, wired sutoconfig, extensible authentication protocol service, human interface device access, smart card, and the wmi perfromance adapter.
To answer your question, initially I was trying to set the adaptor/controller at a default resolution other than 800x600 (the AOA150's default).
Then as that didn't resolve he 'external monitor's display issue, I tried to at least restore the missing console. Since then, I've found the Launch Manager supports the hotkeys, ref. Fn+F5 which has lost it's connectivity, ie; that hotkey no longer functions.
Note the Fn+F5 hotkey toggles the optional display outputs and I've already tried resolving that disfunction by re-installing the Launch Manager, but the issue remains
(even after also re-installing the "Intel Graphics Media Accelerator Driver" software.
So all in all, unless the dongle I mentioned resolves things as far as acceptable usefulness of the external monitor, I'm otherwise left to formatting the AOA150 as I refuse to continue using the monitor at 800x600.
With respect to your saying 'regardless of what I use, I won't be able to display larger than 1024x600', that seems inaccurate as I have screenshots showing the 1024x768 setting (indicating to me that it clearly afforded 1024x768).
So given all I've tried and where I'm at now, I'm severely disappointed that even when I was able to access the missing console and I set it to it's only afforded reasonable resolution (1024x728), the darned thing refused to retain that setting after re-booting.
So everything is telling I might well achieve reasonable usefulness of the monitor by
acquiring and using the mentioned 'USB to monitor' adapter, ie; that dongle seems to amount to what may be loosely referred to as a 'virtual display adapter') and I expect it will serve the needs of AOA150 users who also experience external monitor issues.
Regarding the missing 'console', my re-installations of the "Intel Graphics Media Accelerator Driver" software (x86 version 18.104.22.16826) did not restore the missing console or even functionality of the Fn+F5 hotkey.
Again, I've even re-installed something I suspected may have been of some consequence
in my having removed the VGA Adaptor, ie; the "Intel Chipset Device Software", version 22.214.171.1248. And of note, the Intel website system evaluator identifies the Mobile Intel® 945 Express Chipset Family as installed.
The device manager lists yellow alert entries for 'unknown device' (in place of the un-installed display adapter) and below that it lists (I think) 'vga controller' and below that, 'vga adapter'.
Why the Acer's desktop displays so problematically (on the external monitor), I'm not
sure it's the AOA150 and/or the external monitor that is of issue, but I simply want to enable a quality display in any suitable resolution (greater than 800x600), and as for 16 or 32-bit true color, etc., I could care less which one as I don't game.
What could be somewhat germaine to the issue, is that the TouchMate's 15" screen supports "High Resolution: 1280 X 800 SXGA" (I assume that means 32-bit true color) and the Acer seems to have two default display resolutions (800x600 and '1024x768') and 16-bit true color.
I say 'two' defaults as without any VGA Adapter installed the Acer's default display seems to be 800x600, and with the VGA Adapter installed, the default display, I believe may be 1024x600.
Nevertheless, when I now use the external monitor without either the "Intel Graphics Media Accelerator Driver" software and as mentioned, without the "Intel for Mobile Graphic Media Adaptor" 'console' (as it no longer seems available to me), the resulting external monitor rather poorly* displays a 800x600 desktop.
It displays as missing the edges of all four sides (until I click it's auto-adjust' button), then it displays fine except for a sort of twinkling or slightly jittery appearance.
Again, as I mentioned in my initial post, the AOA150-1029 (AspireOne) and my TouchMate (TM-LCD154) monitor do NOT support 'one or the other'.
The Acer's 10" screen and the TouchMate's 15" screen do not seem to be of any issue.
What appears to be of issue, is that the TouchMate's default display capacity is
"High Resolution: 1280 X 800 SXGA" and the Acer seems to have two default display resolutions (800x600 and '1024x600').
I say 'two defaults' as without any VGA Adapter installed the default display is 800x600, and with the VGA Adapter installed, the default display, I believe is 1024x768.
Nevertheless, when I now use the external monitor 'without' the 'Intel for Mobile Graphic Media Adaptor' console, I no longer find the console available to me, even if I reinstall the Intel VGA Adaptor drivers* (I believe you refer to that as the controller) and now the TouchMate's screen displays the 800x600 desktop except for the edges of all four sides (until I click it's auto-adjust' button, then it displays
fine except for a sort of twinkling or slightly jittery appearance).
Whichever doesn't support the other in this case, is beyond me. Maybe it's both, but I it seems the AOA150 somehow just doesn't support retaining the 1024x768 resolution (after re-booting) and then there may be a necessity for the external monitor to require a 1200x800 resolution (but I think it handles 1024x728 just fine).
Nor does the problem seem to relate to one of 60 vs 75 MHz, as the montior is also a 60 MHz monitor.
So I'm simply resolved to doing one or both of the following; format the darned Acer and/or purchasing the mentioned USB dongle that reportedly affords "most all common resolutions" for "all monitors", apparently by means of that dongle's 'chip born software' and/or it's potentially accompanying software.
But if anything else is left unmentioned, I can only guess that surely my links to a recent (earlier) Intel Adapter Diagnosis, as well as another link to my system properties, should leave no question unanswered, ref...http://www.mediafire.com/file/50tydzqmdzw/2-14-10

So if anyone can add anything useful to this post's string, myself any hopefully others will appreciate it.
