Uses SwitchResX to get the iMac to actually display in 5K?

  No, they used it to turn HiDPI mode off, so that each physical pixel is addressed as a logical pixel, instead of the normal 4 phyical to 1 logical mapping.

  Some people might read that and misunderstand. It does display in 5K whenever possible, but appears to be a half res screen to some software for compatibility purposes. You are still getting the benefit of the higher resolution though, unless you're viewing bit maps that are lower res, or use badly written or non-native software for example. On that last point, how do things like Xwindows or Qt apps work out? Qt should be ok because it tends to use native widgets, as I understand it, but I imagine it depends on how the app is written. I noticed an odd quirk when I got my first retina iPad. Some iPhone apps did render some content at full resolution. I first noticed with iPhone camera apps. The app interface would render at iPhone resolution, but the photos were at full native display resolution. Has anyone noticed any quirks like that with the 5K iMac?
