[quote]If Nvidia ever adds quick profile switching between Extended Desktop and Surround modes, I'll immediately dump my HD5850.
Come on Nvidia; ATi can't get their drivers right, maybe you can...
I don't think anyone can... maybe Microsoft. Switching to Surround or Eyefinity with either card takes about 30 seconds or so while the monitors turn on and off and the computer hangs up and whatever its doing. Even with a toggle key that would be very painful to have to go through each time.You can set two profiles in Catalyst Control Center on ATi cards (one for Extended Desktop, one for Eyefinity), and use RadeonPro (the ATi Equivelant of nHancer) to automatically switch from Extended Desktop to Eyefinity as soon as a game starts and switch back when the game quits.
It all works very nice and seamlessly. Switching modes only takes the card a second (No hanging or anything like you describe).
Why would you need to waste time switching in and out of Surround? Just use Matrox Desktop utility to delineate your physical monitors within spanned mode so that your maximized windows snap within the right monitors.
The Matrox Desktop Utility is a dirty hack, and does not offer the same usability as true Extended Desktop mode.
Some applications ignore the matrox software and maximize to all your displays anyway (not a problem with extended desktop). The Matrox software does not allow Aero Snap to work correctly (extended desktop does). The Matrox software does not confine the taskbar to the center screen (again, not a problem with extended desktop).
If I'm not gaming, I'm using Extended Desktop mode. There is no substitute. Nvidia really needs to add a quick way to switch in and out of Surround, as mucking about in the Nvidia Control Panel every time I want to start a game is WAY too much hassle.
