No standard Resolution 1279 x 1024 is not available, but the difference with the standard resolution can be ignored.
Diagnosis: From some of the suggestions I received, there has been no new ones. However, I actually was not too happy with the solution of the previously chosen to install the drivers that work previously. So, I shall go back to experiment with the monitor that is problematic with Vista. All possible solutions I've tried, as lead by the especial driver, use another card or cable, and install different versions of Vista. Unfortunately, all it does not help. Some suggestions are also recommended to include a new resolution in the nVidia menu. I also include the resolution of the original (native) LCD which is 1280x1024 with all options, but always get an error report. However, when entering the resolution of 1200x1000, "miracles happen" because of the resolution received by the driver.
SOLUTIONS: I also raised the resolution to a resolution to reach the original 1279 x 1024. At this resolution, the horizontal is missing is not too significant and can be ignored. This, the original resolution was finally able to function with the nVidia driver.
