I just got my 5870 and it's a great card but I am having an issue with eyefinity. My primary gaming monitor is a native 1920x1080 and I happened to have 2 extra 19"s (1280x1024) so I thought I would toss those on there and just see what it looked like. I got the setup working fine but when I activate eyefinity it scales my large monitor down to 1280x1024, I understand the need for the vertical resolution to be limited to what the smaller monitors can do, but why the horizontal resolution? The way I understood eyefinity was that it tricks your computer into thinking that you had one big monitor, shouldn't you be able to set the maximum resolution to be what your setup is physically able to handle, so in my case 4480x1024?

All monitors have to be of identical resolution, or they will all scale to the lowest.

I guess I just don't see the reason for the restriction if, in fact, the software does trick you computer into thinking that you have one big monitor. If that is the case you should be able to tell your computer what resolutions will work with that monitor and you would think that if the monitors can display that resolution they will. Obviously it isn't impossible to change the horizontal resolution or else you wouldn't be able to just put another monitor on and extend the resolution further. Does anyone know if the eyefinity combined monitor has it's own dedicated EDID?

One way around using eyefinity is to use SoftTH where you can render the whole frame at a resolution and scale it down to your monitors native res. The issue is that SoftTH hard to get working with some titles and requires a lot of configuration. But it is worth playing around with in your case since, you do have non identical res. monitors.
