Eyefinity Vs Nv Surround

This is an interesting one for me.
I just swapped from a 6950 to a GTX670 and have found that nVidia's implementation of this technology is so much better than AMD's. This is surprising seeing as AMD were first to market with it.

My main reason for switching was that I wanted an upgrade and I fancied a change having had AMD cards for a long while now. I mainly play WoW which runs better on nVidia anyway. Here's what I've found:

With the GTX I can use 2 x DVI and 1 x HDMI for 3 screens. With AMD I have to use a DP-DVI adaptor and suffer screen tearing on the display that's hooked up like that.
The control panel for bezel compensation is much nicer with nVidia. The road is easier to see and align.
But this is the big one for me, probably a WoW thing rather than an nVidia vs AMD thing thing though. I can finally run DX11 mode fullscreen at 3 screen resolution. With AMD I was limited to either running Windowed - Fullscreen, or DX9 mode. DX11 wouldn't work fullscreen in WoW.
 
Despite AMD being first to market so to speak with the tech nVidia had developed their own version around 7 years earlier (see nVidia mosaic) it was briefly available on GeForce cards circa 2001 then locked down to their professional cards until eyefinity forced them to re-enable it for GeForce - so the tech has actually been in development for longer on nVidia.

Agreed. Having tested both fairly extensively the nVidia implementation of it just felt more robust.

Yeah and with nVidia all three monitors don't have to go into one card if you run SLI/CF which is a big plus for idle temperatures.

And you get the option to manually input the number of pixels for your bezel correction which is a massive plus point.

Hopefully one of them will allow monitors with different resolutions to be used together soon :

i.e 1280x1024 - 1920x1080 - 1280x1024

Glad to help - Hopefully it works for you

Let me know how you get on please :)

It does work, but my centre monitors res is changed from 1920x1080 to 1280x1024 when you set up Eyefinity, which looks very ugly since it's the wrong aspect ratio as you'd imagine.

Works in-game, but I didn't notice a performance improvment when running full screen compared to windowed mode stretched over the 3 displays.

So I'll be sticking with using windowed mode / SoftTH for gaming for now.

Worth a try - thanks for letting me know
 
With NVidia, can you switch from surround to non-surround without changing the cable connections?

When I had the 690 (very briefly), it seemed like it was very restrictive on how you could set up the monitors, compared to eyefinity where you could just use any 3 (or 4) of the connections. Maybe I misunderstood something?

The one thing i did like about the nvidia approach is the bezel peak feature, where you can use a hot key to disable bezel compensation for a moment (handy seeing dialogs that are partially clipped by the bezel comp). AMD needs that.
