iMac - Two 20" iMac LCD displays have different brightness levels.

My husband and I each have a white 20" iMac. Purchased them at the same time (Jan 2007), but from different stores.

The problem is that screen brightness differs on the 2 screens. His display is much brighter than mine on the same settings. Even when we've set the brightness to maximum, and chosen the same color profiles (iMac), my screen is much darker, while he can see detail I never see.

I've tried calibrating numerous times, but have never been able to see the same detail he does. What looks like black on my screen isn't black on any other screen I've looked at. Does anyone know of any setting I might be missing? Is it a hardware or software issue?

Thanks.

they used several different monitors in those and if you know for sure that you have the settings the same then you each received different monitors.

i have a 20" as well and im glad i dont have another to compare it to. i read about this a lot after i got mine same year as your and just hoped i got the better one.

Neon-backlit LCDs get dimmer with age. The more they're left on, the dimmer they get. If one of you uses your computer more often, or leaves it on without putting it to sleep, then that could be the cause.

This is a big advantage of the new LED backlit screens Apple has been introducing lately.
