Windows 7: Trying to get Multi-Monitor resolutions set up

Trying to get Multi-Monitor resolutions set up

Hello, I have been having a problem with trying to get Multi-Monitor resolutions set up. On XP my monitor setup is capable of 3360 x 1050; with 7 it automatically separates them and sets each resolution to 1680 x 1050, I would like to enable Span-extended desktop and have had no luck, CCC on XP allows this and on 7 the option simply isn't there. I was just wondering if I was overlooking something.

Updated Specs, I have Hydravision installed, and CCC is at version 9.10 which was released yesterday(Oct 22nd, 2009) It doesn't allow me to extend the desktop to anything above the resolution that CCC or windows allows.

What you are trying to do (horizontal span/h-span) cannot be done.

You need either a splitter, like the triplehead2go or upgrade to a new 58xx series card with Eyefinity.

Thanks, that was the conclusion I was reaching but I just wanted to make sure I wasn't overlooking something, I didn't want to pay for a splitter and also 270-370 for the new 58xx is a bit much lol, I understand that at the moment its an issue with the WDDM driver that vista and 7 use and it won't be resolved until WDDM 2.

How do I access my main monitor if broken in a multi-monitor setup?
I have a setup with 6 monitors. Today my main monitor broke and I couldn't find a way to shut the PC down since I couldn't access the main desktop to get to the Start menu. Is there a way to change which monitor is the main monitor without having access to the current main monitor?
