No.
Shortest sentence ever
The most a display will ever produse is the maximum resolution that it is supplied. Meaning, if the display is sent a 480p signal the most it will do is display at 480p, unless there is an internal line doubler. In that case, it will probably upconvert the 480p signal to 540p, and line double it to 1080i. That is not to say that your DVD playback will BE 1080i, just line doubled to 1080i.
