What resolution is displayed?

I don't see the res in there.  It appears to do the same as xwininfo.
That is, it just reports my virtual desktop size of:

>From xdypinfo output:
[...]
screen #0:
  dimensions:    2048x1536 pixels (321x241 millimeters)
  resolution:    162x162 dots per inch
[...]

Which is not the same as displayed resolution I guess.

I thinks it is one of these:
  "1400x1050" "1280x1024"  "1280x960" "1024x768"

And can be walked thru with C-A +/- of course.
What I want is to verify what res is actually being displayed.
All xdypinfo is giving me is virtual desktop size.
