This KB will give you steps to fix display problems where the bottom of the page appears to be cut off and where black boxes sometimes appear on the screen.
If you're using Windows 7 or 8, the first thing to check is that your display settings are correct. To do that go to Start>Control Panel>Display (you may need to change the view to small/large icons to see this). Make sure your settings are set to "Smaller - 100% (default)" like the screenshot below.
In every browser, the default way to change your zoom setting is to single click within the window so it has focus. Then hold down the ctrl key and press zero, or hold ctrl and press the minus key, or hold ctrl and scroll down with your mouse wheel.
If that doesn't work, you'll need to adjust the settings for your browser manually. Before continuing, close all your tabs/windows then open a new window and go to www.testout.com. Next, scroll down in this page to find your browser and follow the steps for it.
