Changing Your Screen Resolution
Most modern websites can not be properly viewed at low resolutions such as standard VGA which is only 640 X 480 or even 800 X 600 which is known as SVGA.  XVGA or 1024 X 768 or higher is recommended for best viewing.  Many people inadvertently adjust their screen resolutions to low quality setting to make screen objects such as icons and scroll bars larger.  This is unfortunately the wrong thing to do because all of the screen elements in all Windows based operating systems can be adjusted independent of screen resolution.  So what should you adjust your screen resolution to to optimize viewing?  We recommend the following settings:
  • 14" and 15" monitors: 1024 X 768  by 256 colors (or higher) refresh rate should be set at 70hz or higher to obtain a flicker free screen.
  • 17" and 19" monitors: 1280 X 1024  by 256 colors (or higher) refresh rate should be set at 70hz or higher to obtain a flicker free screen.
  • 20" and 21" monitors: 1600 X 1200  by 256 colors (or higher) refresh rate should be set at 70hz or higher to obtain a flicker free screen.

You can adjust your screen resolution by right clicking anywhere on your Windows desktop and selecting "properties".  This will bring up the following dialog box.  In the "settings" tab to the far right, you can select the screen size and color depth. 

If you screen appears to be flickering, your vertical refresh rate is probably set too low.  You can adjust it up (should be over 70 hz) in the advanced settings dialog box as shown:

Then click on the button that lists "all modes"

And chooses a refresh rate over 70 hz
To adjust your scheme and screen elements to a larger size you need to use the "appearance" tab which is also located on the display properties dialog box as shown:

You can select a scheme such as Windows Classic Large, or extra large to enlarge your on-screen elements, while running your system at it's optimum resolution. 

IMPORTANT: If you are not sure of what your monitor is capable of displaying, or if your system is older, you can damage your monitor by operating it above it's highest designed refresh rate.  To be sure, always change systems setting by using the "apply" button first.  If the screen does not display properly, you should switch to a lower resolution setting.
