The first, in the late '90s when all this was happening, there were no 1080p TVs. I've seen some reader comments in response to other articles I've written ridiculing ABC/Fox for this "lower" resolution, but that's unfair in two big ways. This is the format used by ABC, Fox, and their various sister channels (like ESPN). OK, 720p is 1,280x720 pixels, running at 60 frames per second (fps). Let's start with 720p, as it's the easier to understand. Let the argument commence.īecause our TV world is based around 60Hz, and because there's a limit to how much resolution could be transmitted over the air (because of bandwidth and MPEG compression), the two main HDTV resolutions are 1080i and 720p. True, 1080i and 1080p aren't the same thing, but they are the same resolution. And, you can't even get a full 1080p/60 source other than a PC, camcorder, or some still cameras that shoot video. From one perspective, 1080i is actually greater than Blu-ray. There still seems to be some confusion about the difference between 1080i and 1080p.
