Vista - Resolution Reset on Startup

I've got the same problem with an Acer SA90. It's set for 1440 x 900 but about one time in 20 it comes up in a lower resolution. I have to restart the computer to cure it, just logging out and back in again doesn't help, and I have to make sure I don't do anything much first otherwise all my icons get moved about by it.

I also have a similar problem with my Sony Vaio. My laptop monitor works
fine but my externally connected monitor keeps changing screen resolution on
it on. Sometimes I can reset it to the resolution that I want. However,
sometimes my resolution isn't even available to select. This was happening
most of the time when I resumed from the photo screen saver so I quit using
that. Now I just have the problem if I restart the computer. So far the
only work around is to leave the computer on all the time. So much for
saving energy. But the only alternative is to spend sometimes 20 to 30
minutes trying to reset the screen resolution after a restart. Seems to be
some kind of bug with Vista not saving the current screen resolution on an
external monitor. Tried disabling TMM which seemed to be causing similar
problems to other machines with no external monitor but that didn't help mine.

Today I decided I'd try and install XP onto a partition on my drive and
to say the least everything went wrong. Anyway when i got back to vista
the res kept resetting on start up. So i tried everything even re
installed drivers. I eventually decided that it had to be a start up
problem and so I checked out the system config window (Run msconfig).

Under the boot tab there is an option called base video which was
checked. Evidently this option is not supposed to be checked because as
soon as I unchecked it and restarted my system I stopped having the
issue. Hope this helps!

i fixed it by acessing the winRE and running start up repair.
then booted into windows, adjusted the resolution one more time and restart.
after that, every restart holds the settings as they should be.

Hi all,

Relating the problem where Vista resets the video resolution to 640 x
480 upon start-up. I found a solution.
From my own experience (I faced the exact same problem) I thought I
could blame it on hardware, driver etc. I recently upgraded to a new
graphics card and wanted to blame NVidia...

After some investigation I found that there is an option in the
"msconfig" Windows tool, under Boot, called "Base video". This should be
unticked!!!
The function of this "Base video" is to boot with minimum VGA
recources. Hence a LOW resolution.
I unticked it and problem vanished.

Regards
Q
