Practice material and keyboard charts can be better viewed with a screen resolution of 800 x 600 or greater.  The screen resolution of 640 x 480 is strongly ill-advised, since horizontal scrolling may be necessary to view an entire screen.  The recommended resolution is 1024 x 768.

To change or check your screen resolution, right-click anywhere on the desktop screen and select Properties.

Click on the Settings tab and adjust the slider under Screen Resolution to whatever resolution your operating system will permit - click OK to accept.  If the screen resolution is currently at 800 x 600 or greater, click Cancel.
