I'm looking for information on how to do this properly. What I would like to accomplish is having my new GTX 660Ti 3GB drive my two 22" lcd monitors ( witch it does marvelously right now ) and also output video to my Vizio TV. The TV is a model XVT3D554SV. Both of my monitors are using the two DVI connectors. I tried linking my TV with an HDMI cable but I have not gotten any video on the screen nor has windows or the video driver utility ( i forget the name of it ) detected the TV being plugged in. I'm not looking to have output to the TV all the time I would just like to fire up steam's big picture mode and sit back on my couch sometimes. Have i done something wrong or am i trying to do something this card can not handle here?

Response from MSI tech support:

This card can only output to 2 display max using legacy connectivity (VGA, DVI, HDMI), unless if you use DisplayPort as your 3rd display then you can achieve three (3) display output.

Wow, the info is just so convoluted. What a mess.

The 660Ti features page clearly lists NVIDIA surround as a feature tech:

Also the NVIDIA surround tool shows any of the legacy ports used to achieve the 3 monitor surround

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.

I got all pissed off and rewired things last night. Guess what,

I think i have a bad HDMI port on the TV because now everything works as you would expect. 2 DVI powered LED panels and my TV on the HDMI port.

Thanks for the top notch support MSI. At least their product works though!

Let me be the first to say I am quite jaded when it comes to just about anyone's level 1 support. Now, I don't know the level of expertise of the person I got on the phone by calling ASRock but I did assume it was of the "level 1" variety. I was given the short, cover your bases answer and I admit was quite skeptical. Well, this is where I eat a bit of crow because it has solved the issue. The firmware update has produced a completely stable machine for over a week.

Guess there is a reason they throw those out as a first answer
