It's likely when you restored, your video drivers
, responsible for
screen resolution beyond the basic 640 X 480, were sorta "left behind"
I usually consult the data provided by this free program http://www.snapfiles.com/get/everest.html
since it will identify the drivers in use presently & also
list links that relate to your individual requirement(s) for updates.
An added benefit is you will see more about
your computer than you probably have been able to
in the last several months.
So, I think
if you can not right-click anywhere on your desktop
and get the Display Properties
once you get that,
you can not bring up any further
screen resolutions than the default (640 X 480),
Give the driver update a try.
