One of the biggest (ha!) selling points of the new 27-inch iMac all-in-ones is the screen. Twenty-seven inches of IPS glory set at the high resolution of 2560×1440. More’s the pity, then, that the screen, or at least its underlying video hardware, has been a source of frustration for new purchasers.
When the iMacs aren’t having issues where they simply don’t turn on, a number of users have reported issues with flickering screens. The new video firmware specifically addresses the issue, hopefully solving any problems. We haven’t heard of any problems after the install, so if you’ve been having issues with your new iMac, be sure to check it out!
