Ok, 4K is pretty cool. Both my partner and I have 4K monitors now. Mine is my secondary monitor, hers is her primary.
But my main monitor and machine is a 5K iMac. Here’s what 4K looks like inside the 5K iMac (both scaled correctly).
Oh, little 4K, don’t cry in the face of the awesome power of my fully-operational 5K battle station.
By the way, a 27″ 5K monitor has nearly twice the pixels of a 4K monitor — 14.7 million vs. 8.3 million.
