i for power off /on 1 for restart.

there is a Windows XP setting to invert the picture (I guess it is if you hang the CRT upside down from the ceiling). I don't remember the key presses needed, but check under Properties for the CRT

Try the buttons on the front or side of the monitor to get to the menu using the + or - to maneuver Thu the menu items until you see the "sun" that's for brightness the half filled circle is for contrast that helps too.

On your monitor at the bottom there is 3 buttons. The one all the way to the left is the "menu" button. The next one (going right) is the "NEGATIVE" button. The next one (going right) is the "POSITIVE" button.

You can move your screen around. First, start by pressing the menu button.Then, a menu in blue, with a bunch of little white icons will appear. Next, go over two icons by pressing the positive button twice. Then, proceed to push in the "menu" button again. A bar will appear. By pressing your negative button, your screen will move left. Pressing your positive button will make your screen move right. Adjust your screen until the black on both sides are of even proportion. Then, press the menu button to return to the orginal menu you started at. Proceed to press your positive button two more times. Then, press your menu button. Then, once again, use your positive button, and your negative button to adjust your screen to even out the black on the top and bottom.
