Use the following step-by-step procedure to optimize the video image on the Remote console:

1. If possible, view the online test card at:

http://www.blackbox.com/tech_support/ts_upgrades/ts_ss.html

view the test card, display some text in a large font on a white background.

You should also open up other application windows to check the clarity

of text in toolbars and icons on the desktop.
