Apple is indeed planning to release a new version of its 21.5-inch iMac with a 4K display this fall, according to reliable sources. The current plan is to announce the refreshed version of the smaller iMac by the end of October alongside OS X El Capitan and begin shipping the product by the beginning of November. As indicated by references inside of El Capitan, the new 21.5 inch iMac’s 4K display will come with a resolution of 4096 x 2304, which is up from the current model’s screen resolution of 1920 x 1080. Faster processors and improved color saturation can also be expected. The higher-resolution screen will likely raise the price of the new iMac, much like the 5K display raised the price of the 27-inch iMac last fall. Apple may keep around the current 1080P models, much like the lower-resolution 27-inch iMac is still available for sale.
