Note

•	To open Display, click Start, click Control Panel, click Appearance and Themes, and then click Display.
•	A higher screen resolution reduces the size of items on your screen and increases the relative space on your desktop
•	You can switch your screen resolution temporarily to 640 X 480 if you have games or other programs that are set to run at that resolution. To switch, right-click the game or program (on the desktop or on the Start menu), and then click Properties. Click the Compatibility tab, and then select the Run in 640x480 screen resolution check box. Your display reverts to its default resolution when you close the program.
•	Your monitor and video adapter determine how much you can change your screen resolution. You may not be able to increase the resolution above a certain level.
•	Changes to screen resolution affect all users that log on to the computer.
•	Only the recommended screen resolutions are listed. For additional settings, click the Advanced button on the Settings tab, click the Adapter tab, and then click List all Modes. Select the resolution, color level, and refresh rate you want.

How to change the screen resolution in Windows 2000

Minimize all applications so that you can see the desktop.
Right-click anywhere on the desktop background (not on an icon).
In the resulting pop-up menu, choose Properties. This will open the Display Properties dialog box.
In the Display Properties dialog box, select the Settings tab.
In the Settings tab, in the lower right corner, is a "slider" which allows you to change the screen resolution.
Slide this control to the left to decrease the screen resolution and to the right to increase the resolution. The resolution will only change in preset steps usually starting with 640x480, 800x600, 1024x768 and getting increasingly larger. IT is recommending at least 1024x768 unless you have a specific reason to use a lower resolution.
Try changing the resolution one step at a time. Click Apply and then OK from the pop-up message screen to actually change the screen resolution.
If you see a message asking if you want to keep the new settings, click the Yes button within 15 seconds. (If you don't want to keep the changed screen resolution, either click the No button or wait 15 seconds and the change will be reset to what it was before.)
Keep sliding the resolution control one step at a time until you are satisfied. (Repeat steps 7 & 8.)
When done, click the OK button to close the Display Properties dialog box.

At higher resolutions, you may not be able to see as many colors.
Flat panel monitors have a prefered resolution. If you set the display lower or higher, the display will be noticably more blurry. The prefered resolution should be noted in your display manual.
