One last video question - I am stumped

[jdavia]

Some things to look for:

Set the right Video Settings on the TV, Video 1, Video 2 ------
Check the computer Display settings make sure it is on Multiple settings. It may read
"1 (Multiple Monitors) on MOBILITY RADEON 9000"
Click the arrow to see if there may be other choices to choose from, try another choice.
Look in the Advance/Display window. See if the PC is set as No1 and the TV is set to No2.
Click on the Display/Scheme there may be other settings to choose from.

I found that it is a little tricky to understand and set. I would like to use it as single display at times, but do not want to disturb the dual settings. even though I can use Ctrl/F5 to switch, I think.
