Frozen Images on Screen

Maybe try resetting your SMC?

Resetting the SMC of an Intel-based Mac Pro, iMac, Mac mini, or Xserve

Note: This will not delete any data.

The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.

Shut down the computer by going to Apple () > Shut Down…

Select Shut Down or allow the computer to shut down automatically.

Unplug the computer’s power cord.

Wait fifteen seconds.

Attach the computer’s power cord.

Wait five seconds and then press the power button to turn on the computer.

I hope I helped.

Could just be Image Persistence, if you have had a window or image dispayed for a long period of time.

Have a look at > Avoiding image persistence on Apple LCD displays

If it is just a small spot, then see > About LCD display pixel anomalies for Apple products

Huh. I thought Image Persistence only occured on plasmas and old tube style displays. I guess I was wrong.

Austin

That was actually burn, persistence is not permanent.

While we are here chatting. Beware because some of those boiler plate responses that your posting, kind oflook like they belong to other long time forum members.

What are you talking about? If this is about the Kappy thing, I swear to god I did NOT COPY HIM. I am so sick and tired of these acusations. I just want to help people. Maybe he thinks it looks similar because we are trying to describe the same thing or something?

Austin

Sorry..!

I said, "kind oflook like" and wasn't trying to accuse anyone.

I'm sorry too. Kappy just accused me of copying his posts and I even posted screenshots of Time Machine and versions to prove that I wrote the instructions myself and everything and now he's going to the hosts and I didn't do anything. I wrote my instructions myself.

On a related note, is it okay to just leave the settings to default for turning off the display? I have it set to the default (2 mins) and I wanted to know if that might cause screen burn.

EDIT: I'm sorry, I meant image persistence.

Forget it and carry-on. 😉

Personally I feel that the default 20 min is a little long and have my preference set to 5 min in case I dash off without using a Hot Corner.

On my MacBook Air I have it set to 2 mins, on my Mac mini its 20 but I have the screensaver on. I guess I'll turn it down to 5. Thanks!

Also PRAM could be useful.

Command + Option + P + R while starting up intil you hear the chime happen a second time. Then let go of keys.

Also if you have a recovery partition boot to it to check for that image persistence.

Holding just Command + R to boot to recovery.

Play around with Disk Utility to Verify the Disk

Also launch get help online and see if you are getting any persistence.

If yes while in recovery go to Apple Store you need a repair.

If no try safebooting, holding Shift during startup til you get the progress bar.

Test again.
