4K resolution
As noted above, DCI 4K is 40962160, while 4K UHD is 38402160, producing a slight difference in aspect ratio rather than a significant difference in resolution. Traditional displays, such as LCD or OLED, are 3840 pixels across the screen, with each pixel being 1/3840th of the screen width. They do not overlap—if they did, they would suffer reduced detail. The diameter of each pixel is basically 1/3840th of the screen width or 1/2160th of the screen height - either gives the same size pixel. That 38402160 works out to 8.3 megapixels, the official resolution of 4K UHD (and therefore Blu-ray UHD discs).
Destiny 2
The Microsoft Windows version of "Destiny 2" supports native 4K resolution and uncapped frame rate (fps), full mouse and keyboard support, text chat, adjustable field of view, and 21:9 monitor support, as well as being exclusive to Blizzard Entertainment's Battle.net service. Although not native 4K, "Destiny 2" does support 4K enhancements for the PlayStation 4 Pro, an updated version of the standard PlayStation 4 that supports 4K rendering. Similarly, the Xbox One had an updated version called the Xbox One X that released in November 2017 after "Destiny 2"s launch. Bungie added 4K support for the One X, as well as HDR support for both updated consoles, on December 5, 2017. Unlike the Windows version, however, the console versions are locked at 30fps. "Destiny 2" also has an improvement with its servers, which are a combination of dedicated servers and peer-to-peer networking. Lead engineer Matt Segur explained, "Every activity in "Destiny 2" is hosted by one of our servers. ... That means [players] will never again suffer a host migration during [a] Raid attempt or Trials match. This differs from "Destiny 1", where these hosting duties were performed by player consoles and only script and mission logic ran in the data center."
