I frequently give presentations on old projectors with odd capabilities. In Lion it used to be possible to adjust the display attributes of the Mac. In ML this does not appear possible? Is there something I'm missing that is not obvious?
MacBook Pro, Mac OS X (10.7.1)
There are only two display options available in Mountain Lion.
1. Best for built-in display
2. Scaled

For More Info:
dominic,
Do you know if it is possible to make other adjustments through terminal? It is a real pain to spend the first 5 or 10 minutes of a talk messing around with the projector.
You can make other adjustments using the Scaled option as mentioned above. Just pick a resolution compatible with your projector.
Lanny,
I never noticed that. Does it only appear when another monitor or projector is connected? I don't have one nearby right now that allows me to check.
No, it's there all of the time. I don't have another monitor or a projector. By default, when you open Displays, the "Best for built-in display" button is active; just click on the "Scaled" button.
Here's what I get. Must be a difference between retina and regular displays?
Yep, can't see that on my end because I don't have a retina display.
However, I wouldn't be surprised if there was a change to the selections when an external display or projector is made available. Give that a try.
If another monitor or projector is connected, then when you open Display Preferences you will have a separate dialog box on each screen, with options specific for the monitor or projector using that screen (unless your displays are being mirrored, for obvious reasons).
So you will have to wait until you connect to that projector in order to adjust the settings. On the positive side, assuming that it is a single projector you commonly use (in a meeting room or classroom or so on), then OS X will remember that projector and the settings you applied. Actually, since projectors are fairly simple pieces of kit, it will actually remember that model of projector and the settings should be re-applied whenever you connect to another projector of the same model.
OP, take a look at SwitchResX. It will allow you to set up custom resolutions and fine tune all parameters connected to the display, including horizontal and vertical frequencies.

In ML is it possible to fine adjust display hz and size?
