Hybrid SLI will bring multi display to SLI
After years of trying, Nvidia will finally bring dual display support that will work with SLI enabled. Unfortunately, it looks that it will work with Chipset + graphics, which is not what people with two 8800 Ultra cards had hoped for, but at least it’s progress.

Nvidia’s Hybrid SLI performance mode will mean that your chipset gets boosted by an external GPU in performance and that it probably shows another name in the driver so your PC will tell you have better graphics than you had before.

Hybrid SLI driver comes in late January
According to the current schedule, the Hybrid SLI driver for MPC78 chipset has entered the RC1 A01 beta stage. It all went well and this happened a few days ago.

The next step is the WHQL candidate that is expected just after CES or around January 10th, while the production driver is expected around the 20th, or some 10 days later.

Nvidia will be ready with the final driver, the one that will have support for both HD DVD and Blu-Ray in the last days of January.
