SEE OUR 16 ORIGINAL DVDs  There are two TV screen shapes, the square boxy shape of older TVs which have a 4:3 screen ratio, sometimes called Full screen, and the newer screens for HD TVs called wide screen in a 16:9 ratio. Full screen dvds were produced from 2005 to 2010, and widescreen dvds from 2010 to present. Full screen dvds are lower resolution so are best viewed on smaller screens. The widescreen HD Blu-rays are what you need for large to very large screens and in gyms.
