Eyefinity and different resolutions

I've got an HD5850 vid card and two monitors.

Monitor 1: 20" 1680x1050 native
Monitor 2: 17" 1280x1024 native

I enabled eyefinity just to mess around with and it's doing a combined resolution of 2560x1024. This causes my main 20" LCD to look stretched since it's not using the native solution. This is also the same when I try to run games like WoW, SC2, etc.

So is there any way to set each monitor to their native resolutions?

This should answer your question. From the eyefinity FAQ site.

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.

In short you cannot run eyefinity at native resolutions.

It seems clear you can't use the native resolutions, but I may have a cure for the stretching on the monitor. Try enabling GPU scaling and set it to maintain aspect ratio, part of your monitor would become black with no display, but it won't appear stretched. I'm not sure if this works in eyefinity as I've never used it, but it works great for those old games that are 4:3 while new monitors are 16:9.

Yeah I saw that option and tried it out, but it would keep reverting back to stretching the 1280x1024 reso on the 20" LCD. Could not get it to work no matter what I tried.

Hm if you can't do GPU scaling doesn't your monitor have a pillarbox/Aspect ratio option? Every widescreen monitor I've toyed with has it buried in the OSD someplace. If you set it to 4:3 or pillarbox or whatever they choose to call it it should black bar the sides instead of stretching.

I did do Eyefinity on mixed aspect ratios like you are trying and just changed the AR in the monitor settings, didn't bother trying the GPU scaling so don't know if there's a way to get it working that method.
