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:
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:
- A different display (LG) – no static
- A different computer (Mac Mini) – no static
- Different adapter and DVI cable – static remains
- When booting the MBA (not rebooting) – no static
- When disconnecting and reconnecting the 222E to the MBA – no static
