New Cinema Display Colour problems

I started to notice this last week, I have owned the monitor about a month. Not sure if it always been that way or just started.

Thanks,

hi flipflop86,

same problem here: after a specific time my cinema display starts to "shift" colors, from a "cold" temperature to a "warmer" one (and back and forth). this continues to happen also after i did a "expert calibration" in the display settings...

if anyone finds out why this happens please let me know, otherwise i will return the display...

best wishes,

chris

I am having the problem as well. I've already replaced the display once and the replacement is doing the same thing.

Same problem here. I actually just experienced it tonight. The display rapidly shifts from normal color to red tint and then back again. I am using 2.8 Macbook Pro with GT graphics (better performance) and new 24" LED display. It does it quickly, back and forth. Ugh.

Same problem on my brand new monitor... only one week old. I use it on a new MacBook with the NVIDIA GeForce 9400M

sounds like a popular problem...

Just noticed the same thing today.

I've seen the "color temperature shift" problem on both my LED displays driven by a 2.4 MacBook. I called Apple and got a case number. Judging from my conversation with the phone support agent (professional as always), this seems to be a recognized problem as he had a specific remedy.

I was directed to go into both the root and then the user library and delete the preference: com.apple.windowserver.plist (there were several in my User Library). Then I was directed to zap PRAM. I didn't see the problem occur after that. . .but. . .a couple of days later when I was working at my other location with my second LED display, after about 8 hours of the MacBook running, the problem started again.

Pure speculation here, but I would surmise that the issue is in the MacBook and not the monitors. I also suspect that it may be a thermal issue with the new video cards. Another call to Apple will be in order after the New Year holiday.

I have this problem too - a subtle shift in colour every few minutes or so. I haven't reported the problem to Apple, as it seems like it's not a fault with the monitor, but thought I'd mention it as other people are having the same problem.

Cheers,

Dave

I have this problem also, and I have dust under the glass. Maybe it's time to return it..?

I have the sam problem, running the display with a new MacBook. Check out this thread: http://forums.macrumors.com/showthread.php?t=619417

I have also experienced this color shift problem. I first noticed it while working in the finder. The blue shading in there was shifting color and I thought I was seeing things. It happened a number of times right in a row, though. It doesn't happen very frequently overall, but when it does it is very noticeable!

I finally gave up and took the display back for a refund. After exchanging the display the new one had the same issue. So, I decided to exchange the MacBook just to see if that was the problem and it still did it. So, it is definitely a problem affecting all of the new displays. I suspect that anyone who hasn't noticed it just hasn't used it long enough. It would only happen after the computer had been on for about four hours without a break. So, anyone who plans to purchase this combo to use as their main system should be aware that you will most likely have this annoying color shift if you use the system all day long as I do mine. Until this problem is fixed, the MacBook + 24" LED combo is not an adequate replacement for a desktop.

I have tha same problem here in Germany. It runs for a month now and i have the same problem. I wait a while because maybe its a OS problem.

I just want to chime in and say that my 4 day old LED 24-inch display is experiencing the same color shifts as described here.

This is on a 2.4 Macbook (also 4 days old), and uptime is defiantly over 4 hours.
