Some are. The larger iMac screens, eg 24" and up, are IPS displays which
don't exhibit the banding. The older iMacs and all the Mac notebooks
have TN displays which do show banding. That's why I have a secondary
IPS LCD monitor on my iMac that I do all my image editing on.

Mmm not sure it is the graphics card.
It is most probably the screen. And no, Mac screens are no better than
PC screens :(

Hah, the plot thickens. I can see the banding perfectly clearly on my
everyday MacBook Pro. But on our big high-quality NEC monitor, I
can't. But even on the big monitor, I can see the bands in that .png
file.
Interesting because this is the first time there's actually been an
observable effect of the fairly limited graphics card in the laptop.
Thanks everyone for making me take a second look. -T

Tim,
I don't see the banding either.
When I've had this kind of problem,
the banding was caused by display resolution.

Look at the green bokeh-fied background and observe the obvious lines
that look like elevation lines on a map, let's call them "bars", as
the green brightness drops off. They ain't there in the .dng, and
after the first cut, I specified 100% JPG quality and they're still
obvious.
It gets weird... I took a screen grab of the Lightroom window, in
which none of those bars are visible, and saved to a .png file, using
built-in OS X facilities, the PNG created by Preview. Obvious bars! I
put it online at http://www.tbray.org/tmp/screen-grab.png - I thought
.png was uncompressed!
I'm sure that a silky-smooth jpg of this picture could be created.
But I don't know how.
It's not too bad here. I wonder if you're pulling an Ann and have something
set to too few bits.
I'm having the same issue - I cannot see the isobars/lines/whatever at all.
Silky-smooth on my screen (Chrome browser on a Macbook)
