|I'm assuming the ATI card has a SVideo port built into it, and the TV has a SVideo port built into it, and that you have a SVideo cable connected between the two SVideo ports (4 pins on either end) . |
On the TV you must select a video source other than TV. E.g. most TVs have a TV/Video button on the front of the TV, and on the remote for the TV if it has a remote.
RIGHT click on a blank part of the main desktop screen in Windows, select Properties - (goes to Display Properties) - select the Settings tab.
XP (Win 95 and up) enables only one display by default.
You should see two display screens there on the Settings window.
In XP or 2000, if you hold the mouse cursor over each display, Windows will show you if that display is Not Active. If it's Not Active, RIGHT click on that display and click on Attached to enable it.
IN 98SE and previous back to 95, and probably in ME , RIGHT click on each display screen there - if it's already Enabled and the only active screen, Enabled is checkmarked and greyed out. If it's not active, you can Enable it.
Windows will retain the second display being enabled as long as the SVideo cable is still connected to the TV, but if you disconnect the SVideo cable and boot the computer at least once while it's disconnected, you will have to enable the second display again after you have connected the SVideo cable again.
DO NOT plug in or unplug the SVideo cable while the computer is running - it's NOT "hot pluggable".
