    I have a 2011 Macbook Pro hooked up to the older plastic style 23" Cinema Display with an Apple DVI to ADC adapter. It has red noise on the blacks, and blueish tint on the whites. Is it software or interference or what is causing it? It's not all the time, but more often than not.

    The red image should be solid black:

    Strange. Does it show up on screenshots? Are you using an Apple mini-DisplayPort to DVI?

    Does it change as you wiggle the connections?

    Looks like it does, when I wiggle the thunderbolt port, so its not getting a good connection from the laptop. Both are brand new, so I know no dirt is in there.

    Guess it's time to visit an Apple Store. Do you have any other DVI monitors you can try it with?

    PS: I love those 23" ADC screens. So amazing and great to use. Nice to see you're keeping yours alive.

    Wow, how old is that display? Perhaps it's time has just come to an end?

    They were made from 2002-2004. The problem isn't the screen, it's the mini-DisplayPort connection.

    Hahahah no buddy. The issue is with a 2 week old adapter on a one month old laptop.

    I hope its a faulty adapter, really don't want to get the laptop repaired.

    Got it plugged in now and the dots are gone, but it just seems like a weak connection. I have another ACD to test, but only one DVI-MiniDisplay adapter

    this happened with my cintiq 21ux. it ended up being the mini display port to dvi cable (which was brand new). I thought my cintiq was bad until i talked to wacom. he knew of this problem and it was common. he suggested to me the kanex mini display port to dvi cable. this made the issue go away. I have had no issues with black on my display anymore. get the kanex adapter and you wont have issues.

    I may just do that. Does Kanex make just an adapter since I can't use a cable, as the DVI ADC adapter already has a cable that is a male port, a cable would be another male port. (Already made that mistake with a monprice cable). Thanks!

    to the best of my knowledge the kanex adapter is female on the dvi side and male on the mini display port side.
