flashing pink and blue squares on display
I have an Apple Cinema Display 30" DVI (2560 x 1600) with a stock ATI Radeon HD 5870 1024 MB graphics card that I am using with my Mac Pro (Mid 2010) that has 2 x 2.93 GHz 6-Core Intel Xeon Processor & 32 GB 1333 MHz DDR3 ECC RAM. I am running OS X 10.8.5 (12F45). A couple of weeks ago it started flashing pink and blue squares on the display. It keeps getting worse, although I am still able to use it. Restarting does nothing to help. Is this display ready to fail?
Mac Pro, OS X Mountain Lion (10.8.5), 32 GB RAM, 5.23 TB HD
