anyone got an idea what could cause this and how to fix it?
it's a 2011 iMac no apple care.
 
Actually I've got a better picture.
The screen isn't completely black, just darker on the side.
I've attached a picture of the mouse on the dark area.

Is this looks like a screen or something else? Cable? Video Card?

Thanks!
 
Do you have any idea how to fix it?
I really dont want to spend another 600 USD for screen replacement.
 
What's happened to the pictures? Would love another look now I realise you have the 2011 model.

I don't think it's a burned issue...
Especially, because I had nothing round on that part of the screen that could burn into, and if I turn the screen off for overnight and back on, the dark spot is exactly on the same place.

I've took another picture of it in a different angle, and that makes me think your first comment, that the screen is somehow separating from the glass or so?
If I Look it on the side, this is how it looks like:

Still no picture showing for me?

As I couldn't confirm this issue without re-seeing the pictures I quickly remove that responds. Regarding the "display burn in pixel retention issue" which I removed it would continue to be there after having the machine off.

Anyway that issue is less likely and is one of the reasons I removed it from my response quickly afterwards.

The issue on thinking of can't happen on your generation of iMac as your display and the front glass a separate. 2012-13 models the glass and display are one and I've seen some issues with the lamination process.

That's why I removed it the moment I realise you had a 2011 model.
