If the notebook's graphics solution is the only problem, then the adapter "should" work. But without your internal graphics working, installing the drivers for this adapter might be a tough challenge.

Oh, note you said in your opening post,
The internal adapter works fine for general surfing
bypass internal display card that has failed
I personally would expect one of those adapters to provide good "game play". For one, I don't think any come with their RAM.

To be more specific about video problem, if I install either of nVidia or Toshiba's version of video driver, Windows will not start in normal mode, only safe mode. When I boot in this manner, a conflict shows with card 1 under resources where it shows it is attempting to use resources allocated to PCI controller and option to change resource allocation is disabled, card 2 shows no conflicts. If I disable card 1 and leave card 2 enabled, windows still goes into an endless reboot sequence. When I disable both, Windows starts normally and shows that it is using a standard VGA adapter with no RAM for video. Although performance is degraded, it is still usable to a degree.
At one point, I was very adept at systems and hardware as I was a programmer for 11+ years. That ended in Dec. of 2001 so I have been out of the loop so to speak since that time.
I hope I have clarified things to a degree for you guys. I appreciate your feedback and support greatly. Thanks.

3D Video Controller PCI\VEN_10DE&DEV_0407&SUBSYS_FF001179&REV_A1\6&1B4B69F4&0&00000008 The drivers for this device are not installed.
When I attempt to install driver, appears to succeed, then rolling reboot begins again. Same problem arises when I boot in Safe Mode and review display adapter settings.

You were right the first time - the "native" resolution is 1440x900 with 720p content - at least according to these specs.
Correct display mode was 1920 x 1080 for 1080p mode
Standard VGA mode is the industry standard default for all operating systems, graphics (cards or integrated), and monitors. This is basically the lowest common denominator (default drivers) so all devices will on the same page out of their respective boxes. This is the same as used in Safe Mode. I would boot into Safe Mode and make sure the resolution is set to the native 1440x900.
This still sounds like a driver issue to me. Or maybe you need to disable then re-enable SLI.

I have read reviews online that state that the nVidia series of graphic adapters in laptops have a reputation for overheating at some point and failing. I really believe that is what has happened here.
I was hoping to find a satisfactory alternative to replacing the laptop or replacing the video adapter via a USB adapter. Your responses tell me that I have no valid alternative at this point.
