Future-proofing HTPCs for the 4K Era
 

4K (Ultra High Definition / UHD) has matured far more rapidly compared to the transition from standard definition to HD (720p) / FHD (1080p). This can be attributed to the rise in popularity of displays with high pixel density as well as support for recording 4K media in smartphones and action cameras on the consumer side. However, movies and broadcast media continue to be the drivers for 4K televisions. Cinemal 4K is 4096x2304, while true 4K is 4096x2160. Ultra HD / UHD / QFHD all refer to a resolution of 3840x2160. Despite the differences, '4K' has become entrenched in the minds of the consumers as a reference to UHD. Hence, we will be using them interchangeably in the rest of this piece.
