Hoe kan ik de resolutie van mijn laptop blijvend aanpassen? De lagere resolutie wordt nu steeds na elke herstart teruggezet door Vista.?

Ga naar het start menu van Vista. Tik daar in
msconfig.
Ga naar de tab boot.ini en zorg dat er GEEN vinkje staat bij "/BASEVIDEO".

The actual culprit is TMM, Vista's process that looks for multiple
monitors and attempts to intelligently modify resolution. If you aren't
using multiple monitors, you can disable TMM:

1. right-click on 'computer' and select 'manage'
2. on the left pane, expand 'task scheduler' then ' task scheduler
library' then 'Microsoft' then 'Windows' then 'MobilePC'
3. select TMM in the center pane, then on the right pane, choose
'disable'

Now you should be able to close your laptop, let it go to sleep and
when it wakes up it will still be in your preferred resolution (also,
the screen won't go blank for a second right after waking up)

I'm not sure if you will have to also disable it for future windows
sessions (maybe in the 'triggers' tab on the bottom of the center
pane).
