Wow, the info is just so convoluted. What a mess.
The 660Ti features page clearly lists NVIDIA surround as a feature tech:http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-660ti/features
Also the NVIDIA surround tool shows any of the legacy ports used to achieve the 3 monitor surroundhttp://www.geforce.com/hardware/technology/3dvision-surround/system-requirements
The surround tech includes a 4th monitor as a "monitor panel" but does not seem to be available if you read the surround tech configuration tool that way.
Also, what is never addressed is if the 3 monitor display setup is only used in gaming and for spreading a single game frame across the 3 screens or if they all can be configured independently just as i do my 2 current panels. In either case the configuration tool does highlight all 4 connections as available for use in up to a 3 panel setup. Yet, MSI's answer explains why my TV gets no signal right now.
Looks like I've got some testing to do. What a mess.
