Well I just got a new DVD player that can play either 480p or 1080i on my Toshiba CW34X92 HDTV-Ready TV. I was wondering which one is the best mode?
Q I have a Sony KWP-65HD1 and its display format states that 480p input will be displayed as 480p, 720p will be displayed 1080i and 1080p as 1080i. Is 480p better than 1080i display?
A This all has to do with the TV's maximum scanning frequency capability. 480i uses 15.75 kHz, and 480p uses 31.5 kHz. 1080i uses 33.75 kHz, which is just a little more than what is needed at 480p. 720p requires 45 kHz, and it is more expensive to make a TV with high scan rate capability. Your TV is engineered to scan at no more than 33.75 kHz, so that is why 720p and 1080p are downconverted to 1080i. 480p and 1080i are fine as is, so they do not get changed. Native 1080i will look better than 480p.I'd imagine that there's no clearcut answer to this questions and it may come down to a personal preference. Perhaps making minor adustments to the TV will help.
