The computer display industry maintained the 16:10 aspect ratio longer than the entertainment industry, but in the 2005–2010 period, computers were increasingly marketed as dual use products, with uses in the traditional computer applications, but also as means of viewing entertainment content. In 2014, "21:9" screens with pixel dimensions of 3440 × 1440 (actual aspect ratio 43:18 or 2.3 8) became available as well. 370, however commonly referred to as "21:9" for easy comparison with 16:9) appeared, which closely approximate the common CinemaScope movie standard aspect ratio of 2.35–2.40.
In 2011, 1920 × 1080 (Full HD, the native resolution of Blu-ray) was the favored resolution in the most heavily marketed entertainment market displays. By about 2007, virtually all mass market entertainment displays were 16:9. However, around the year 2005, home entertainment displays (i.e., TV sets) gradually moved from 16:10 to the 16:9 aspect ratio, for further improvement of viewing widescreen movies. The 16:10 ratio allowed some compromise between showing older 4:3 aspect ratio broadcast TV shows, but also allowing better viewing of widescreen movies. When good quality alternate technologies (i.e., liquid crystal displays (LCDs) and Plasma displays ) became more available and less costly, around the year 2000, the common computer displays and entertainment products moved to a wider aspect ratio, first to the 16:10 ratio. The 4:3 aspect ratio was common in older television cathode ray tube (CRT) displays, which were not easily adaptable to a wider aspect ratio. On CRTs there was often a difference between the aspect ratio of the computer resolution and the aspect ratio of the display causing non-square pixels (e.g. The 16:10 aspect ratio had its largest use in the 1995–2010 period, and the 16:9 aspect ratio tends to reflect post-2010 mass market computer monitor, laptop, and entertainment products displays. The 4:3 aspect ratio generally reflects older products, especially the era of the cathode ray tube (CRT). The favored aspect ratio of mass market display industry products has changed gradually from 4:3, then to 16:10, then to 16:9, and is now changing to 18:9 for phones.
