Dell has just announced a brand-new 27inch external display with an insane resolution of 5120×2880. Pixel counts of this magnitude were thought to be several months out, stretching into mid 2015, so Dell’s abrupt announcement has come as a bit of surprise. In summary, the 27-inch panel has 14 million pixels across its surface, resulting in a PPI of 218. This is the same density as a 15inch Retina MacBook Pro, but obviously much much larger.
The monitor is expected to be available by the end of the year.
What’s notable about this resolution is it shows that a Retina iMac is now very feasible. 5120×2880 is exactly double 2560×1440, the resolution of the current 27 inch iMac, in each dimension.
