Hello and Welcome to Bleepingcomputer.
First, I am not sure how you tried to access your screens resolution settings, so please forgive me if I am suggesting something you have already tried.
You want to first try doing the following. Right clicking the desktop, then choosing properties, then settings. Look to see if you can slide the screen resolution up to 1024 by 768.
I do see how-ever where your monitor does not support resolutions above 1024 by 600, but windows might still allow you to over-ride that restriction by doing what I suggested above.
Being that your device is a mini 100, you might be stuck with not being able to do this.
You could also try updating your video drivers to the latest ones available from your vendor.
