| OdinHades said: And you really don't want a 4K TV to upscale 720p, trust me. 720p was never the real deal. It was a compromise to lower the cost in the early days of HD. The problem is, that it just doesn't want to fit with the other resolutions. You see, 4K is exactly four times 1080p. So if you upscale 1080p to 4K, you get four pixels for one pixel. The results are just what you would expect from a native 1080p display. With 720p that won't happen. |
Why not? You see, 4K is exactly nine times 720p. So if you upscale 720p to 4K, you get nine pixels for one pixel. The results are just what you would expect from a native 720p display.
pixel doubling (horizontally and vertically) of 1920 x 1080 = 3840 x 2160
pixel tripling (horizontally and vertically) of 1280 x 720 = 3840 x 2160
Upscaling from 720p to 1080p is a much bigger problem than upscaling from 720p to 4K. The mess is in the present with the most common resolution 1920x1080, not in the future.
