Hello all,
I have documented this in another thread but I thought it would be better to dedicate a thread to this "problem".
I bought a new entry level iMac the other day. At night, before putting the computer to sleep, I often put the brightness of my screen all the way down to 1 notch so that when I wake the computer up in the burning the display doesn't burn my eyes.
So, I did this with the new iMac. When I woke up in the morning to check my email, the computer came out of sleep fine, but the display was flickering. As if it was pulsing between a brighter brightness level and a duller one.
The problem continued when I increased the brightness to 2 and 3 notches, but seemed to disappear after that. I have been able to recreate the problem many times (it is not intermittent) and it is also noticeable if you shut the computer down on 1 brightness notch and start the computer up a few seconds later.
I PM'ed someone in this forum who bought the very same computer as me and he was able to recreate this "problem". I was wondering if all of the new 21.5" and 27" iMac users could try the following:
I don't know if this problem is that major as I very rarely use my machine on such a low brightness level, but in the morning, when you've just woke up even the 1 notch of brightness can seem exceptionally bright!
Let me know if you can recreate this problem on your new iMac. I think it could have something to do with the new LED backlit display.
Thanks in advance,
Shaun.

- Put your computer brightness down to 1 notch.
- Put the computer to sleep.
- Wait about 30 seconds.
- Wake the computer up from sleep, and focus on some part of the screen.
- Does it flicker? Does it disappear when you increase the brightness level?
