iMAC display resolution unexpectedly changed

by cattaand / September 29, 2012 4:19 AM PDT

Hi, my old iMac (10.4) suddenly changed the resolution of my display and I can not change it back. It only happens for my account, and not for the other two accounts on the same computer.
I went to system preferences and display, but the resolution is already the highest.
Can somebody help ?

Sounds like a corrupt account profile.

Create yourself a new, admin, account and log into it.
If all is well, resolution wise, then move all your documents, music, pictures, etc., over to the new account

Thanks for your answer. I found the solution in the Apple forum: I accidentally turned on the "zoom" function. The solution is: system preferences / universal access / turn zoom off.

Thanks anyway.

Thanks for telling.

This is not meant to insult you in any way. Just a note. It's something we often see.

You write "My iMac changed ... and I cannot change it back".
You should have written: "I changed ... on my iMac. I don't know how I did it and so I don't know how to change it back".

Your iMac didn't do anything. You did.
As I said, we often see this, and it's quite understandable.

thanks Cattaand for the useful answer, I have had exactly the same issue and I certainly didnt turn on the Zoom function. Btw, going to Apple store and speaking to 5 different guys, no one knew the answer so it wasn't that easy.
Kees_B useless patronising.

it's very easy to accidentally turn it on

Option + Command + 8 will turn on the Zoom function.

I have had my cat do it by laying on the keyboard, each of my Grandchildren have done it by "typing"

The resolution of the screen does not change, as noted by the OP's reference to the System Preferences > Display pane, just the view point changes.

It does not come on by itself, it has to be turned on

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
