Hm, the 3520x1200 is actually a MergedFB framebuffer with pseudo-xinerama. I
don't know how to query the xinerama info to compare but it appears Mythtv is
getting the wrong dimensions below (1920x1200 is the other monitor, not the
one it's on). So that's already an error.

In addition I'm not sure where the 407mm x 305mm figures are coming from. The
actual figures for my monitors according to the X log are:

(II) RADEON(0): clock: 154.0 MHz   Image Size:  519 x 324 mm
(II) RADEON(0): clock: 157.5 MHz   Image Size:  388 x 291 mm

And 407x305 doesn't match either of them.

Is there some command-line tool to query xinerama info to see what information
mythtv is getting from X?
