1080p Does Matter â Hereâs When (Screen Size vs. Viewing Distance vs. Resolution) What the chart shows is that, for a 50-inch screen, the benefits of 720p vs. 480p start to become apparent at viewing distances closer than 14.6 feet and become fully apparent at 9.8 feet. For the same screen size, the benefits of 1080p vs. 720p start to become apparent when closer than 9.8 feet and become full apparent at 6.5 feet. In my opinion, 6.5 feet is closer than most people will sit to their 50″ plasma TV (even through the THX recommended viewing distance for a 50″ screen is 5.6 ft).
