Hi Chris
Consumer graphics cards with multiple outputs can be configured to create a virtual desktop which spans across multiple outputs, i.e. Eyefinity or nVidia Surround. If you set up your desktop as such, then Ventuz can use that setup as well and you can render across several outputs. Outputs are always synced.
NO! We had some cases where we had GPU's with mixed output connectors. (HDMI/ display port/ DVI) in this case it can happen, that outputs are NOT in sync!

That was exactly why i was asking about GeForce Cards.
In theory when in surround/eyefinity mode thet act as a single canvas, but for some reason they drift by a frame or two from time to time.
It gets really ugly on LED walls.
I just wanted to check as per Nvidia documentation they are supposed to be synced perfectly and they are actually not.
Guessing mixed connections HDMI/DVI/DP does make things go bad, Tho even using only the DP ports of a card doesnt seem to make any difference.

Thanks for the input!

That is very true. It never happened to me because i never use different output types. Sorry about any confusion.

WX9100 in combination with S400 sync boards is awesome! Not only will you get tearing but also heavy hardware freezes. Also the support rocks! They'll come back to you once a week asking for you driver version, Ventuz version, DX version, ...
