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