1080i - The Myth :: Your TV 1080i TV is not 1080 (anything)

To get 1080 (anything), you MUST buy a 1080p TV.
It is really common sense—every TV that I have ever seen sold in the USA that was advertised as 1080i/720p only had a pixel resolution of 1366×768 (or something similar). That is to say that a 1080i signal will be down-converted by your TV to 720p. It is simply a matter of hardware limits in that, a 1080i TV does not have enough pixels to produce a 1080 lines of resolution. Irregardless of what any salesperson may say, if your TV could handle 1920×1080 resolution it would be sold as 1080p. 1080i is simply a marketing ploy—I am amazed that it has held up as long as it has. If your TV is 1080i, simply use 720p.

I disagree. It’s simple math. Look at the number of pixels on any TV. Unless the TV has a resolution of 1920×1080, it will not be 1080i or 1080p because both require a resolution of 1920×1080. I just bought a 42″ LCD that was sold as 1080i, but the resolution is on 1366×768. Thus, whatever image my xBox, DVD player, etc. pumps out WILL be down-converted to fit my TV’s resolution.
