If you have an ATI or Nvidia video card, the driver may support
custom resolution settings. You will have to research how to
find that box, in each case.
If you want to play around, and use a third party tool to set
the resolution, you can use PowerStrip. Note that PowerStrip
does not help with all hardware types for graphics, and
is poorly suited to deal with the GPUs on laptops. But if you
have an ATI or NVidia desktop video card, it should work with that,
and a trial is available for 30 days (so you can test it). The
main advantage of using this tool, then setting 1024 x 920, is
to see how your new monitor responds to such a request. It should
still handle it, because monitors have been multisync capable for
some time. What I cannot predict, is whether it will resample, or
use black bars, or whatever. The monitor, if it so chooses, can
also display "Out Of Range", using the monitor OSD (on screen display).
Using PowerStrip, you can experiment with the settings.
But if you can find the custom resolution box, in the ATI or
NVidia control panel software, you do not have to pay anything
to use that.
The horizontal value should be divisible by 8. The vertical divisible
by 2. 1024 is divisible by 8. 920 is divisible by 2. So you meet the
basic rules for an initial resolution choice.
This is an example for the "classic" NVidia control panel. This
control panel is no longer used, and a less-well-decorated one
has been written and substituted. In any case, this is to
demonstrate what a custom resolution setting box may look like.
If you cannot figure out how to get this from your current graphics
driver, then you can always download PowerStrip and use that.
