Kepler Multi-Display Details? They're a bit vague.
  1 / 3    
After searching around for a while now and reading more than a few reviews, there is very little information on the multi-display functionality provided by the new GeForce GTX 680. It is clear that it can run 3 screens in surround plus an additional display, however nowhere does it mention whether or not the 4 displays can be run independently of each other, operating as individual displays of (possibly) differing resolutions and refresh rates.

In addition to that, it hasn't been mentioned if the exact procedure for enabling/disabling a surround resolution (rather tedious at the best of times) has been streamlined or if profiles are now available for different monitor setups/layouts.

Do not take this answer as final, because I have not found a verified source, nor do I have the GPU.

I would say no, it is not possible to have 4 active independent displays from the one GPU.

The following screenshot is the only evidence I have of it this - it is missing the 'activate all displays' section of the NVCP

The 4x displays from one GPU in the 'Surround + 1' config still follows the old nvidia rule of 2 screens per GPU - because technically the 'spanned' display is only 'one' screen, its just shown over 3 displays.

Well if that's the case it makes my life easier (ASUS HD7970-DC2T on the way, multi-display functionality being the deal breaker), appreciate the fast response.
Only thing I noticed from your screenshot is the 'Resolutions' button in the Surround setup window, haven't seen that before so be interested to know it's purpose.

Based on the guru3d review it looks like you can do this...

We just had a quick chat about 3D Vision surround but Kepler goes beyond three monitors. You can connect four monitors, use three for gaming and setup one top side (3+1) monitor to check your email or something desktop related.[/quote]

It should be like any other windows multimon setup. You can probably pick one to be your main and then select any of the 4 as secondary displays. Just like windows multi-mon with two or three displays. The surround option just lets windows see three of the displays as one large display. So, expect to be able to run windows programs on all 4 displays but render full screen on only one or three if they are surround.

I've scoured for info on this as well. I specifically would like to know if I can run a game in surround with all three monitors set at different resolutions.

Not ideal I know, but still would help with some "peripheral" vision.

The one unavoidable requirement for Surround is that all three monitors have the same resolution, refresh rate and sync polarity. More than just "not ideal", your intended goal is unsupported as well...

Thanks for the info. I was hoping for similar support as eyefinity 2. I will probably still go with this nVidia card to avoid mixing an AMD card with the nVidia 560 already in my case, and for the huge performance gap on battlefield 3, but it's unfortunate that the nvidia680 won't support multiple resolutions like the AMD7970.

However, I might sleep on it for a few weeks and see if I can stomach the lower performing 7970 for 50$ more to get eyefinity 2.

Can't have my cake and eat it too when AMD/nVidia is involved. :(

The Geforce GTX 680 can support up to 4 display in Windows Extended Desktop mode. In 2D Surround and 3D Surround, the three monitors have to be running in the same screen resolution.

That still remains a rather cryptic response, can the 4 displays can be run simultaneously, operating as individual displays of differing resolutions and/or refresh rates.

For example, if all screens are running separately to each other, maximise functionality remains 'correct', not spanning a window across multiple monitors without the need for additional software (the solution for surround resolutions).


Would love to hear back from Tyrdstorm (or anyone else with first hand experience with this) as it seems his cards arrived already :).

Simple Google search turned up results saying yes, it can and is easily done without Surround involved, to drive 4 monitors independently at their own resolutions. Realize this though, that will likely A: make the card run at full speed clocks all the time, like current cards do with 2 monitors plugged in a lot of the time. B: I'm unsure of if the 4th monitor's Display Port plugin will need additional power ala Eyefinity when you go past 3 monitors per card (from what I understand) does need additional power of somesort... I'm unclear on how that works as I've never tried it myself on either brand.

When spanning it creates one big desktop 5760x1200 across the three monitors. They have to be the same resolution as it creates one single screen. It looks like they've been putting a lot of work into making it better for normal desktop applications in this mode, but they still have a little work to do. Normal programs seem to work fine and you can maximize them onto each "virtual" display. Some custom programs such as Photoshop don't seem to handle it as well and still maximize across all three displays. The start menu being restricted to one screen was a nice touch, but you lose the ability to auto-hide it which I prefer. Still, I can get over the loss of auto-hide since this is much improved from previously having to span the start menu across all three.

When you run a fourth screen however, it is completely independent form the three spanned monitors and works just like normal extended desktops as seen below:
[img]http://bryceapps.com/Files/Junk/ExtendedDesktop.jpg[/img]

I would however still like some more explanation about this screen:
[img]http://bryceapps.com/Files/Junk/AdjustDesktop.jpg[/img]

I did have Aspect ratio selected and I was having a lot of video crashes... but I'm not sure if it was related or not. I was having a lot of stability issues at first, but now it seems they've worked themselves out. Not sure what fixed it though. Anyway, hope this helps a little, feel free to ask any specific questions if this isn't the answer that you needed.

On a side note, Activate all displays is definitely still there. You just have to have two cards installed to see the option:
