You will need to provide more information if you want someone to help you. What projector are you using? How is it connected to your Mac? What have you done already to try to remedy the problem?
I tried to connect my MBA 2011, I7, with an external projector through thunderbolt/vga cable.
After the upgrade to os mountain lion, the "detect monitor" button dissapeared and nothing happens when i connect the cable.
I tried to restart the MBA and nothing again.
Same problem here
Hardware:
Macbook Pro 13" Early 2011
Problem:
After upgrade to Mountain Lion I can't connect ANY external display or projector.
Thins that I've already tryed:
1) PRAM NVRAM reset - DIDN'T WORK
2) Fresh install Mountain Lion - DIDN'T WORK
3) Try others HDMI or VGA adapters - DIDN'T WORK
4) Downgrade (reinstall) Lion - all my adapters and external display worked again
Here is the chronology of the problem:
1) With Lion - Everything worked fine
2) Upgrade to Mountain Lion (10.8.0) - My HDMI adapter stoped work, but my VGA adapter worked fine
3) Update to Mountain Lion (10.8.1) - My VGA adapter died too. Now none of them work. No HDMI and no VGA.
4) Update to Mountain Lion (10.8.2 12C53 - I have an mac developer account) - DESPERATE TRY TO SEE IF APPLE FIXED, BUT NOTHING. SAME PROBLEMS, ANYTHING (HDMI and VGA) WORK.
If you are still having problems with "Detect Display" I too realized with Mountain Lion it disappeared from "system preference" - Display. I found though by pressing the option button "Detect Display" appears.
I have the same problem you are having "Mac os x mountain lion dosen't detect external projector." So when I go to "Detect Display" my Mac still doesn't detect the external device. Hopefully it will for you.
Did you find a solution? I have the same problem.
I ended up taking my mac to the Apple store. They found out my issue was with the port -- a hardware issue. Had nothing to do with Mountain Lion. So there is no solution for me except changing the port -- and with the age of my mac, I'm not willing to do that. Bummer
