Help with screen resolution (NEED IMMEDIATE HELP)?

At this point, I can not really see this that will well, therefore I’ll attempt my finest.
I just simply uninstalled a course that I installed just a few minutes ahead of that (my silly friend failed to give myself the agreement code >.<), so there seemed to be no employ keeping the idea on my computer.
Even so, now my personal screen resolution seriously isn’t as huge as before as I go to change it in control Panel, my best option is the one I am currently jogging (not the most important size I had before).
So how do i expand the maximum resolution on my computer
Im running Glass windows 7, in addition, on a Toshiba laptop computer.

Firstly, give us one or two years to help GUESS the particular make plus model.Adding another year or so so we could guess the present resolution.
CHANGE:Go into the Toshiba web site and get a hold of the visuals driver for this model and also reinstall this.

open ctrl panel > showcase > display screen resolution > maximize it while you need but I do think the default can be 1366 *768.
