There's one major problem thats plagued the Apple 30" for many years. The thread has been locked because of it. Nobody knows how to fix it. Not even Apple. Applecare just tell people to reinstall OS X. It doesn't solve it. Nothing solves it, not even replacements.

Green and blue dancing pixels so many has named it, but its actually DVI Noise.

You know I've heard of this as well.. it really made me think twice about the 30" ACD... but I've found a thread someone after googling about the 30" Dell having this issue as well with some users.. maybe its just the lcd panel that has this issue?? I'm actually considering just another 23" ACD just since it will be much cheaper as well..
 
Man I sure do want that 30" ACD but I guess that price tag is just too high, it keeps me questioning its price and keeps telling me to stay with the 23" ACD since its not even 1k... but then it'll be covered with applecare warranty.. so... hmmm

As far as I'm concerned there are 3 pc things worth splurging on:

Monitors
Chairs
Keyboards

These things if treated right will outlast every other component of the system.

I have 2 logitech dinovo keyboards that I'll never get rid of because I love them too much and will buy dinovo replacements if they die.
I have a leather computer chair that is a bit rough but I love it too much so yea, it stays till death.
I have 2 30" ACDs and I will keep them both until they die and probably add a 3rd at some pt.

Life is short and the tech cycle is even shorter. Get the 30 :)

Interesting, but you seem to be in a small minority that hasn't encountered this problem. There's a thread somewhere here that iGary suffered this same problem. A few years back.

There's thousands of people out there that have had 3 - 7 replacements at a time, and the problem still remains. Each unit is brand new. They have had their graphics card replaced. CPU's replaced, power supplies replaced. Even the power brick replaced from the ACD unit. Until the very end they have actually had their whole tower replaced and the problem still remains. Even people have had it on the Apple laptops.

Some just returned the 30" display and got their money back.

It is even more worrying that so many people have said Apple are looking into it, and there's never a solution. Months/Years past. The same thing from Apple has been said by their technicians to this day. Same thing, it goes no further. Nobody knows. Replacement after replacement the same thing happens. Round and round the spin dryer people go.

I think it is alarming that all Apple can offer from Applecare is reinstall OS X. That is obviously from their dumb idiot script board. Still it does not solve it.

Interesting, but I actually suspect I'm in the vast majority of ACD owners, whom have never posted anywhere to say "my 30-inch ACD is working fine."

However, I acknowledge I can't back up my suspicion - it's just my impression from reading MacNN and MacRumors a lot over the past year, and this is the first I've heard of it. Do YOU have documentation you can cite that supports your assertion that the vast, vast majority of 30" ACD owners have this problem?
 
The dancing pixel issue is well known to me. Back in the day when I used the Apple 30 inch displays with PC's it used to happen. I troubleshooted it for days on end and came to the conclusion that SOME video cards did not adhere to the DVI dual-link spec (required to drive the monitor at an optimal 2560x1600 resolution) and the artifacts appeared as a result. After switching video cards (On the PC) and then later on switching to a mac the problem completely disappeared. I can whole heartedly recommend this monitor to anyone using a Mac Pro. A thing of beauty.

Thats good to hear, when I had the 30" ACD last year for a full week before returning I never had the dancing pixel problems with my 2.66Ghz 4 core machine.

The only problem that I had was the left side of the screen was a bit brighter than the right side. Like if I drag a white background window over to the right side the white will more light greyish, it was very annoying. I set the brightness notch to 6 out of the while 16 but when I had the brightness up higher then the whole screen seemed to have the same brightness.

But I hope its not like that with the majority of the 30" ACDs and that I had one with a problem...

Documentation, like what? does the Apple discussions count?

Why are people still getting it on a 2008 Mac Pro with a 8800GT. :confused:

It's not as if 8800's are the first card to run Dual Link DVI.

People have been there. Replacing every part in their machine, and the problem still remains. New machines. New displays. It does not go away.

When I first got the display I was using it on a Windows PC with an Nvidia 7800GTX card and the problem occurred frequently (like 50% of the time). I changed the card to an 8800GTX and the issue went away completely. Now I'm using a Mac Pro with an 8800GT card and it's back every time the monitor goes into power save mode, and occasionally when the machine reboots (you can see the green pixels on the apple boot logo).

The other thread has been going on for 3 years now with no answers - I doubt this will ever be fixed.

Z.Sulic said:
I have this problem too but the fix does not work for me. I have a 30" Cinema Display and a brand new Mac Pro with the NVIDIA GeForce 8800 GT graphics card. This is actually my second Mac Pro as I exchanged the original one, which was having the same issue, thinking that the graphic card might be bad. This was done after speaking with a support specialist whose only advise was to reinstall the O/S which did not work.

If it was as simple as that it would have been solved a long time ago. Granted, the problem does not happen when the display is on 24/7. The dancing anomalies happen after the display has came out of standby. So something screws up with it for the power saving setting set on the machine. People have replicated this so many times, but no solution. As long as the display never goes into standby set by the system. You'll never get it.

Though thats not very handy if you get called away for something and forget to put the display to sleep/standby.

Do u know if u put the whole mac pro to sleep manually and wake it up that it will have the dancing pixels??

I didn't say it didn't exist. I acknowledge that some small percentage of people who buy an ACD have this problem, or think they do. But I would like you to support your assertion that "it's only a small minority" that doesn't have the problem. I see nothing there that supports your claim.
 
You guys think that the 30" ACD are more susceptible to problems in the future (hence not last long as say the 20" or the 23" just because its bigger/more backlight bulbs/components?) I guess longevity?? I know I've used the 23" cinema display for a good 7-9 months now and I only use it at 4-6 notches at the brightest and its still plenty bright.. but I'm curious on how long the bulbs will last on the 30" ACD... I guess I could use the 30" ACD's backlighting around 4-6 notches as well.
 
I decided that tomarrow I'm going to go buy the 30" ACD at my local apple store, since I already have the applecare for a monitor I'm going to use it on the 30" and sell my current 23" to cover almost the half the cost of the 30" :D

Wait a sec, are you saying that if you have applecare and decide to switch from 23" to 30" they will pay the difference or part of it?
 
Is there a separate applecare for displays? I know there is one included with the mac pro, but only if the display is purchased at the same time on the same invoice. It's not something you can grand-father in at some later point in time.
 
so far that I've used the 30" ACD, I've never seen this dancing pixel I guess I'm one of the lucky ones...

How long have you had it so far... have you left the display off for quite some time? as in via standby mode, not sleep mode from the power saving. When the display sleeps by itself. It appears for those when you struck a key or move the mouse. The screen awakens all covered in these pixels.

What is quite puzzling, the amount of people I've seen the most with this problem seem to be UK people. There has been some non UK people with it.

I had it for the past 5 days and put my mac pro to sleep every night and wake every morning. With no problems but the uneven backlighting drove me crazy on the right side of the monitor.. made grey look like white on the right side.. so I returned it today and complained and very happy to see the $$ back and I'm back using my perfect 23" ACD.

I loved the space of the 30" but in the end I found it a bit too big for me and the 23" was the perfect size.
 
I hate how Google/Youtube butchers the quality of videos.

I was hoping it would show it but its killed off any details showing the pixel problems.
You can barely see it on the edge of the shadows, and the edge of the turn off display widget.

I can produce this as many times as I want. Make the pixels show, make them disappear.

I'll have to upload the proper lossless version somewhere else later today.
 
How are the ACD for Gaming?


I would say that a 16 ms Response time is not exactly ideal for gaming..Although excellent for everything else color related...I think I am opting for the Dell2408WFP myself....But the Apple sure id Peretty..!!:D
