OK All:
I have finally resolved this issue satisfactorily !
There are actually two ways to use the dual monitor features of GF4. However, they are mutually exclusive of one another.
One is
Windows Dualview which is pre-configured with Windows 9x and Windows XP operating systems. (Strangely enough however, not Windows 2000.) In essence, these Windows OS will automatically detect a second display device upon startup attached to your system. If Windows XP has detected a second monitor on startup, two monitors will be displayed in the Display Properties setting of Windows and you can configure each as independent desktops with independent resolutions.
The alternative way of using dual monitor with GF4 is
Scan/Clone Mode. This mode is specific to the NVidia GF driver. This is the mode I was getting stuck in as explained in my previous message.
I'm guessing the reason that I was not enabling Windows Dualview mode is that I did not have my TV-Out connected when Windows XP started up. Once I did that, XP booted in Dualview mode and I have my two monitors showing on the display properties setting page where I can configure each independently.
There is a straight-forward explanation of this on page 24 of the
NVidia Display Properties User Manual .
So now I have what I've been aiming for. With MJ9 Preview, I'm able to send the MJ windowed display to my secondary monitor (TV) and play in full screen mode.
I'm still not happy with the image quality of the full screen MJ display on the TV. It is blurry; the cover art is not bad but the MP3 properties (Artist/Album etc) can not be read because the font is small and blurry. So I need to find a way to increase the image quality (I'm running 800x600 on the TV and can't seem to change this is the display properties in either direction). Are there ways within MJ or different skins which give good/better results? This may best be left for a different forum thread.
Thanks to David, Mirko, and JimH for all the help.
