Totally agree with your point. Earlier it was so convenient and now with Mountain Lion, one has to open the display preferences and press additional buttons to enable mirroring.
Hope Apple fixes this soon.

I agree this is a problem. I have a new MBP and have been using a VGA adapter with it since purchase, and the Mountain Lion upgrade seems to strip the menu bar display preferences. My old monitor is wonky and I have to switch the resolution back and forth to keep it from being fuzzy, so I really miss having the display preferences icon in the menu bar. I'm going to leave feedback on this one.
In general terms, Mountain Lion has been the buggiest/feature-droppingest? OS release I've had to deal with in a long time. I'm suprised and disappointed in Apple, unfortunately.

Reporting the same problem: no menu bar icon for display mirroring on 13-inch, Mid 2010 MBP running 10.8.
External display is via DisplayPort.
Really makes using this MBP to present to clients a pain.
For the life of me can't understand WHY Apple would remove such a harmless + useful feature of their OS.
On Windows 7 or even Windows 8RC you can hotkey to toggle displays... it's essential.

I had to downgrade to Lion. You can add the Displays icon back to the menu bar, however, for those of us with an "old" Mac, you'll never be able to adjust brightness or change resolutions from the Displays menu bar icon--your only option will be to "Open Display Preferences" ...
As a side note, for me, this forces me to apply the "Microsoft Rule" to Apple; I won't even consider new Apple products until it's first service pack or second generation, since they won't be clear on the removal of features, key components or otherwise just tell me to spend another $3,500 on a MBP so I get the functionality that previously worked flawlessly.

Same problem wih Macbook pro mid 2012, mountain lion. ""Open System Preferences > Display, hold Option key and press Detect display at the bottom"- but it doesn't detect. it detects only when the mac is reboot. I am tired of rebooting every time I connect to projector.

I find that instead of rebooting that Dinaching reported, that I have to plug in the display adapter several times before the MacbookPro recognizes it. It took me 8 minutes to get the projector running, which is pretty bad in front of customers. This needs to be fixed by Apple! A stupid change by a code writer who must never have tried it out in real life situations.

My situation is similar to geoErin. 2010 MBP 15". I need to adjust my display preferences fairly frequently because I use my external monitor in different rooms and its position relative to the MBP needs to be adjusted in Displays->Arrangement when I switch. Menu bar Displays item was great, it was also a good quick check that the computer correctly identified the monitor when I plugged it in.
AOC external 1680x1050 connected mdp/tbolt adapter to DVI. Display always connects - ALWAYS - but once or twice the computer misidentified it as a generic display. I guess that was before the Mt Lion upgrade.
Mt Lion display in menu bar NEVER, EVER shows up.

I also move from various offices and conference rooms where I am always plugging into an external display of some sort. I am quite dissapointed that the menu bar icon does not appear, even when clicked in system preferences. I am glad I am not the only one having this issue. Hopefully it will be fixed in the update this fall...**fingers crossed**

To make this even more confusing, my menubar icon has 'magically' reappeared. I didn't change any particular setting, but I change my Display Preferences fairly frequently, so I can't say what combination of factors might have let this happen. Weird, MLion, weird.

Hopefully it was a software update? Can't wait to check it out when I get back to my computer.
Currently Being ModeratedAug 23, 2012 4:48 AM (in response to Vintage White)
After geoErin's post I checked for new software, but mine was up to date, unless they haven't released the new software for the UK yet? I have no idea.
Ps I don't like how all software updates now work through the app store, I preferred it seperate like in Lion.

Update: I have just checked the app store and I had an software update for MLion, there were a few fixes but non for this display icon issue.
(MLion 10.8.1, MBP 13" Mid 2010)

Stumbled across SwitchResX http://www.madrau.com/indexSRX4.html
Does what the previous menu icon for Display Prefs used to do and a ton more.
....but costs $20.
MLion so far is the poorest value upgrade I've ever experienced, particularly if I factor in the 2 days it took to rebuild my MBP after a failed install.
MLion: making Windows look like value!
