Just wondering, what is the expected (or quoted) life of the backlight on an (ie my) iMac

Does screensave actually also extend the life of the illuminator ?

I presume sleep does, as it appears to turn off the backlight

Similarly, does less brightness extend the life ?

Do these concerns also relate to the inverter ?

What iMac? LED Backlight?

Screensavers will do nothing either way.

No iMacs have LED backlight displays. The screensaver doesn't really help save backlight, but turning the display off. All LCD's will eventually go dim, no matter what the brightness is on. Treat it just like a regular fluorescent light in that regard. So no matter what, it's gonna dim

Interesting, i thought the dimness was only applied to Plasma TVs
