IR on late 2012 27" iMac

Congratulations... It sounds like you have, after trying really hard and putting a lot of effort into it, you have achieved IR.

 

So you intentionally tried to get IR? It's awfully hard to sympathize.

 

You know, I always thought that how hot your computer got was one way to get it, but after researching it, that turns out to be incorrect. I'm still sceptical, but the facts are it doesn't seem to matter.

 

Really think you should go get it replaced. Up to you if you are going to create new issues, but either way, take it to Apple Store and get a new one.

 

I see you're in Sweden. Generally a pretty cool place. How high was the temperature?

 

Accusing me of "trolling" is the typical generic non-intellectual and defensive answer. But to remind you again, you said "I did that check board grid IR test and I could leave it on for hours with no signs of IR whatsoever."

But ok go ahead and return it since it doesn't pass your torture test. If you want a perfect LCD panel, go get an Eizo or something.

Who's stupid now?

 

Why is it so hard to sympathize with him?

He checked for IR when he first got his iMac (since he likely read that some people were having IR issues) and back then his display seemed perfect. Fast forward a few months and now he's randomly getting IR when he least expects it. Yes, things happen but it still kind of sucks to be in his position.

Lighten up.

I went through 4 units that all had various issues (including heavy IR while performing the simplest tasks) before getting a full refund. I've always read of horror stories and never thought it would happen to me... until it did. For now, I'm squeezing a few more months out of my Macbook Pro until I can see what the new Mac Pros are like.

Now that I think about it though, I keep my room warmer than usual... especially during the winter months. Perhaps that had something to do with the IR that I encountered. Whatever the case is, I hope you're able get to the bottom of your IR issues and resolve them.

 

I am not the one who accused anyone of "trolling". I made a simple statement, it's hard to sympathize. That's all.

But anyway, the level of anal-ness is getting too high here.... i fully expect to see a thread soon on the purple smudges you get when you leave fingerprints on the screen....

 

What is IR?

I thought it was InfaRed.

 

Image retention.

 

I thought IR was infrared also. I think people shouldn't use abbreviations without first defining them, especially when using a common one like "IR" for a non-standard term.

I have no image retention (IR) on my iMac either, and I've used it for playing games at 35*C ambient temperature - it got quite loud, though.
