The 5K Retina iMac’s screen runs at 60Hz at 5K resolution
I'm very glad to see arstechnica using the blurbusters tool for testing monitor rate!It was initially a Win32 exe that I created 5 years ago [1] with a simple idea to display very distinct frames, back when people were using all kinds of silly less accurate methods like timers to do these things. Blurbusters did a great job of making the tool more accessible to more people (visit website vs. download and run an unknown exe). They were even respectful enough to ask for my permission before adding it their website (which I of course was happy to give permission to, and not that I would mind too much if they didn't, it's a very simple idea after all).[1] http://hardforum.com/showthread.php?t=1423433
