According to WitsView, as quoted by DigiTimes, Apple could release a 27-inch Retina iMac before the end of the year.
The monitor would display a 5120 x 2880 resolution, WitsView said.
Apple is said to launch the new iMac alongside several other “Ultra HD” panels in Q4 of 2014.
The report adds that the average price of a 28-inch Ultra HD monitor was $630 last month.
The focus of monitor vendors is mainly on displays with diagonals of 27, 28 and 32 inches.
