*-* Update *-* I’ve posted about this again here
I’m a big fan of multiple monitors. Even since i first tried it in Windows 2000 i haven’t looked back.
I struggle when going back to a single screen as it’s so convenient to be able to view more than one window at a time.
For example, If im on a support call i can remotely control a server and view a knowledge base article at the same time
Even now while i’m writing this i have someone elses blog post for me to refer to.
Anyway the point of this post is something i saw on Download Squad talking about support for multiple cards in Vista
After reading the post i was a little concerned as couldn’t bear to “downgrade”. The worry is about using cards from different manufacturers as the full Aero interface requires that they have the same drivers. The post says that the Aero interface wont be available. I don’t think this is the case. From what i can gather one of the graphics cards will actually be disabled. You’ll still get your Aero interface….only on one screen though
The original post that Download Squad links to has a link to an article on the Microsoft site that tries to explain the situation. It’s not immediately clear what the situation is but my take on it is:
Dual View – One graphics adapter, multiple screens
The article quite rightly points out most modern graphics cards have multiple outputs so their wont be an issue.
This is the setup i have. My PC has a standard VGA output and a DVI output which runs my two screens. This wouldn’t cause any issues in Vista as it’s only a single driver.
Homogeneous Multi-adapter – Multiple adapters, one graphics driver.
This is where you have two cards that use the same driver. The cards don’t have to be identical. As long as they are running the same driver.So you could use for example:for example, NVIDIA GeForce 7600 NVIDIA GeForce 6600 with no issues. Slot types are not important either
Heterogeneous Multi-adapter – Multiple adapters, multiple drivers.
This is where you use two cards from different companies. An NVIDIA and an ATI card for example. In this situation you would be forced to use the driver model for which ever card was the “POST” adapter (generally VGA)
I only think this is going to give a problem to people who use LOTS of screens (i.e 4+). As detailed above you can use a single adapter for two screens so the issue doesn’t arise. The cards DONT have to be identical. Just the drivers. So the situation isn’t as restrictive as i first thought!
Also if you were building/buying a new system then you would just need to think a little more carefully about what your using to drive the screens.
