Can nVidia Surround drive 2 Refresh rates?

[Sin_Chase]

As per subject.

Could I run 2x24" 60Hz display as monitors 1 and 3 and the central primary monitor at 120Hz and still get the 120Hz benefit from it?

Reason I ask is I already own 2xHP LP2475Ws and have no desire to dump them. One day I might invest in 120Hz but would like to keep my money invested in the HP monitors as Surround screens - They aint cheap!

The only info I can find is the official 680 blurb stating:

Any combination of connectors and monitors is A-OK in 2D Surround, though in 3D Vision Surround the two DVI connectors and single DisplayPort connector must be utilized, and users must have three matching 3D Vision monitors.

This would indicate any 3 monitors is fine for 2D but 3D surround must have matched monitors.

It does not make specific reference to mis-matched refresh rates though?

I would say no. Multiple monitors are generally treated as an extended desktop. I don't think windows has the coding to separate refresh rates for individual monitors.

Windows certainly does for extended desktops.

Whether nVidia Surround does is a different question.

Thinking about it more.

Even if nVidia surround could handle it, could the game?

I imagine despite the Surround technology the game will still only push a single refresh rate, in which case it will be limited by the smallest possible in the bank of displays - 60Hz.

Unless nVidia surround overtakes this aspect and can accept 120Hz from the game and 'downsample' to the 60Hz screens? Seems doubtful.

I stand corrected

The game will just see it as one big screen anyhow - some games do monitor for vwait themselves tho a lot don't but even if they do or even if they don't the driver/GPU will have the final say on VSync.
