Possibility of installing 4K resolution Retina display in the new 21.5-inch iMac

It is pointed out that Apple is preparing a model with a 4K display on a new 21.5-inch iMac.

Pierre Dundmont said that he found a description of the 4K resolution, which seems to be for the 21.5-inch iMac, in the beta version of the new OS for developers "OS X 10.11 El Capitan"blogIt reports in.

"4096 × 2304 Retina" written on line 105 of the image below is the resolution of the problem. The resolution of 4096 × 2304 is not present in any models of 21.5 inch iMac, 27 iMac currently on sale, and is not present in "OS X 10.10.4 Yosemite" of the current OS.


Since it is not meaningful to convert a 27-inch iMac with a 5K (5120 × 2880) model to 4K already, it is thought that this 4K resolution will be installed in the new 21.5-inch iMac. Since the resolution of the current 21.5-inch iMac is full HD (1920 × 1080), if a 4K 21.5-inch iMac appears, it is likely to get about 4.5 times the resolution. However, there is always the possibility that "24-inch iMac is reviving at 4K".


In addition, regarding graphics, I have also found descriptions such as "Intel Iris Pro Graphics 6200", "AMD Radeon R9 M380", "AMD Radeon R9 M390", "AMD Radeon R9 M395", "AMD Radeon R9 M395X". As expected, the new iMac seems to be equipped with a 5th generation Intel Broadwell processor.


Screenshots suggesting the existence of the new Bluetooth remote controller as follows are also released. Perhaps it may be the appearance of a new Apple TV that supports multi-touch trackpads.


A new iMac equipped with a 5th generation Intel Core processor that integrates the Intel Iris Pro Graphics 6200 is expected to be released in the fall of 2015.
