I have a Philips 222E display connected via a mini-DP to DVI adapter and DVI cable to a Macbook Air (mid-2011).

Every time that the MBA wakes from sleep, the display shows this static: enter image description here

The static is replaced with the proper desktop image after around 20 seconds, or after a power cycling the display (which could take only 10 seconds but is highly annoying just the same.)

Things I tried and their results:

  1. A different display (LG) - no static
  2. A different computer (Mac Mini) - no static
  3. Different adapter and DVI cable - static remains
  4. When booting the MBA (not rebooting) - no static
  5. When disconnecting and reconnecting the 222E to the MBA - no static

I've seen this as well with my MacBook Pro, but rarely. I disconnect and reconnect the display cable. As you say, it's annoying. –  Doug Harris Apr 27 '12 at 14:48
    
disconnecting and reconnecting causes the arrangement of windows across displays to get screwed up, so it's out of the question for me (far more severe than a few seconds of annoyance) –  GJ. Apr 27 '12 at 16:03
    
I see this as well with a Mac mini late 2012 on an external display connected with a Mini DisplayPort to Dual-Link DVI adaptor (and I don’t see it on my other monitor connected via HDMI->DVI). This isn’t a fix, but an easy way to restart the displays without reconnecting them is with the keyboard shortcut Command-Control-Eject, then press any key or click the mouse. –  Zev Eisenberg Nov 26 '12 at 3:37
