<P> By 2010, virtually all computer monitor and laptop manufacturers had also moved to the 16: 9 aspect ratio, and the availability of 16: 10 aspect ratio in mass market had become very limited . In 2011, non-widescreen displays with 4: 3 aspect ratios still were being manufactured, but in small quantities . The reasons for this according to Bennie Budler, product manager of IT products at Samsung South Africa was that the "demand for the old' Square monitors' has decreased rapidly over the last couple of years". He also predicted that "by the end of 2011, production on all 4: 3 or similar panels will be halted due to a lack of demand ." </P> <P> In March 2011, the 16: 9 resolution of 1920 × 1080 became the most commonly used resolution among Steam users; the previous most common resolution was 1680 × 1050 (16: 10). In April 2012, the 16: 9 resolution of 1366 × 768 became the most commonly used resolution worldwide; the previous most common resolution was 1024 × 768 (4: 3). The third most common resolution at the time was 1280 × 800 (16: 10). </P> <P> Since 2011, several monitors complying with the Digital Cinema Initiatives 4K standard have been produced . The standard specifies a resolution of 4096 × 2160 and an aspect ratio of almost 1.9: 1 . </P> <P> Since 2005 most video games are mainly made for the 16: 9 aspect ratio and 16: 9 computer displays therefore offer the best compatibility. 16: 9 video games are letterboxed on a 16: 10 or 4: 3 display or have reduced field of view . 4: 3 monitors have the best compatibility with older games released prior to 2005 when that aspect ratio was the mainstream standard for computer displays . </P>
