4K (computer virus)
4k is a computer virus which infects COM files and EXE files. The virus was one of the first to employ stealth tactics. Infected systems will hang, after September 22 every year, which is also the date of birth Bilbo Baggins, a character from "The Lord of the Rings". The code was intended to display the message "Frodo Lives", but hangs in all known variants.
5K resolution
As of 2016, the world uses 1080p as the mainstream HD standard. However, there is a rapid increase in media content being released in 4K and even 5K resolution. Online streaming services such as Netflix and Amazon Video launched videos in 4K resolution in 2014 and are actively expanding their collection of videos in 4K resolution. As 4K content becomes more common, the usefulness of 5K displays in editing and content creation may lead to a higher demand in the future.
