My iDrive screen on cold mornings seem to be quite dark. The contrast and brightness are not at normal setting. After I drive few minutes it starts to get back to normal contrast and brightness. Anyone notice this?

Normal. The iDrive screen has a light sensor (there's a tiny, circular electric eye at the bottom center) that works in conjunction with the auto-dimming rear view mirror (which has electric eyes on the front and back of the mirror). So if you're in your dimly lit garage and back out into the sunlight, the display automatically brightens.

Thanks, but I don't keep the car in a garage. I thought it may be from cold, but of course it can be from the light. How fast it self adjusts to light changes?

Within seconds once I'm out of the garage. But you bring up an interesting point since you don't have a garage. Perhaps (like a home PC monitor) it's just the LCD display slowly powering up after coming out of sleep mode.

Yes, some have reported that cold can cause the screen to darken. Mine appears darker on cold mornings as well, but nothing I've ever felt the need to bring to the dealer...

I garage mine, but have definately noticed the darkening on cold mornings...

Thanks. I don't feel it needs dealer attention, as I've seen many LCD's doing that on different devices. Also it gets normal in few minutes. It's just that I wanted to be sure that this happens to all E60's, not only on mine.

Thanks for confirming it.

IMHO it's a thing of temperature not too much about light sensors. Mt lcd also does that and i think its quite normal for any lcd to go a bit darker, less colourfull, even slower in response. It happens in all kind of electronics due to the LCD construction. Look at cell phones that were exposed to cold or laptops or whatever. As soon as the temperature starts to grow then the lcd comes back to it's optimal settings.

Normal. Due to the TFT (thin film transistor) screen technology very cold mornings can cause screen to appear a bit darker. After a while when car and screen gets some warmth all should be fine. Nothing to report to a dealer.

I frequent the Corvette forums and have heard of this problem on their LCD screens as well. It seems the backlight does not like cold weather, no solution for their problem yet though as it's hard to reproduce. How cold was it exactly?
