resolution problem

I decided to load the new nvidia beta driver, everything went well till I went to set up the triple screens...I was previously running 6000x1080 when I setup up the surround to configure it downgraded to 4020x1024 and won't give me any options to increase it in NVIDIA resolution or Windows display options? Any ideas or help would be greatly appreciated! I even reverted back to the original driver and its still doing it...when the system loads its in 1080 but once the triple screen activates it downgraded :( Cheers
