Eyefinity with different sized monitors

I have 3 17 inch LCDs and a 22 inch LCD monitor I plan on using eyefinity with. Until I am able to afford two new 22 inch 1920x1080 monitors I'd like to know if I could have a setup like this:

22" 1920x1080 monitor in center with 2x 17" 1280x1024 monitors on either side acting as one monitor. with a 17 inch acting as a separate monitor on top.


If I can't do that I know at least I will be able to have the three 17s down below acting as one monitor with the 22 up above, but I really would like to have the 22 inch right in front of me.

You can use eyefinity with different size monitors and screen resolutions. Not a problem. You just need to "order" them in your desired layout within Catalyst. Last, make sure you are using the current drivers from ati.com for your flavor of Windows. Good luck!

No you can't. You can have extended desktops and multi-monitor setups at different resolutions, but the actual eyefinity has to have the same screen resolution on each screen.

I stand corrected. From the Eyefinity FAQ:
Can I support different resolutions?

All monitors running in a Display Group or cloned modes must be running with the same resolution. If monitors have different native resolutions, the highest common non-native resolution between the monitors will be used when creating Display Groups. Monitors running in extended desktop mode can have independent resolutions.

So, you have to use the same res? Can it be 3 different brands? I have a Acer P215H which isn't sold anymore, so could I buy a sony or something, and it work? So could I have 3 different brands of monitors that support the same res?

Could it be two 21.5 inch monitors and a 23 inch monitor all supporting 1920 by 1080?

Thanks
