I don't understand why the tv resolution is limited to 1080p, and why we are limited to that particular reolution. Right now a lot of high def shows are being shown only in 720p, which is a lot lower resolution, yet its called the same thing as 1080p (high definition). I guess what really confuses me is that computer monitors for years have supported much higher than 1080, and these computer monitors are usually smaller than 19 inches. Now that people are spending thousands of dollars on giant screens that are 50, 60, or even larger, they have a limit to 1080, at the same time people with tiny 15 inch screens are playing games at 1920 resolution. Wouldn't it make more sense for a 15 inch screen to have a lower resolution than a 60 inch screen? Why can't cameras and shows be shown in higher than 1080? Why can't these mega screens support higher than 1080 for future use?
