I have an external monitor connected with the Aplle VGA adaptor to my MBP.
It has been working fine for the last year.
Today I installed 10.7.3
And now I get the message "Input Not Supported" on the external display.
Not impressed.
Any ideas or do I have to roll back this update.
Cheers.
MacBook Pro, Mac OS X (10.7.2), 10.7.3
Hi,
I have the same issue since installing 10.7.3. I can't even access the screen properties anymore since the external monitor was my primary screen. verytime I plug it in, the Apple menu is moved to the external display.
Monitor was working fine with 10.7.2, and still works fine with other computers.
OK now it gets silly.
I have also had a problem, since I instaled Lion, that when I open my MBP the screen is black and no amount of encouragement will bring it to life.
So, I have to switch on my external monitor. My deskptop thern appears on the externam monitor, so I select "Detect Displays" from the menu bar and, kazam, my MBP screen comes to life and the desktop moves there.
It only remains for me to switch off the external monitor and wait for Apple to provide a fix.
Now, remember my current problem, in that the external monitor wil not work and shows "input not supported".
So today I opened my MBP and sadness, the screen is BLACK. So I switched on my external monitor and WAHEY! it worked and the desktop appeared on the external monitor.
Excited at the prospect that my problem had somehow magilcally fixed itself overnight, I selected "Detect Displays" and my MBP screen duly appeared and the desktop meved there.
The external monitor then stopped working and showed the message "Input Not Supported"
I also have a related VNC problem that is still outstanding, so I think it is fair to say that there are several issues around external monitors with Lion.
And there's more,
If I switch on MIRRORING then this WORKS and the external monitor correctly shows the desktop.
Switching off mirroring returns to the "Input Not Supported" message.
Cracked it with some help from Eric.
My external display is an AOC 2236
On opening the displays icon in the menu bar, a list of the available displays and their supported resolutions appear.
The 2236 has 2 lines showing identical information of "1920 x 1080, 60Hz", one ticked and one not.
So I selected the one that wasn't ticked and, hey presto, the screen now works and the list of available resolutions now correctly shows only one line of this info.
Happy days
🙂
u got ur solution??? if yes please tell me
Hi, I have exactly the same issue described by Motud2. I too have a AOC monitor(not sure what model#) but I too have it working fine when I check the mirroring option. When I take it off, it shows as "Input not supported".
@Motud2 - you seem to have solved this issue but I couldn't follow the steps you have put down. When I go to Menu>System Preferences>Display I do not see any resolutions listed, please see the image attached - thats all I see.
It would be really helpful if you could help me figure this out.
