When is 720p Not 720p?

Posted by Hemos on from the the-tricks-of-the-eye dept.

Henning Hoffmann writes "HDBlog has an interesting entry about many home theater displays.
Home theater displays around the resolution of 720p (most DLP, LCD, and LCOS displays) must convert 1080i material to their native resolution for display. No surprise there. But many displays do this by discarding half of the 1080i HD signal, effectively giving 720p viewers an SD signal - not watching HD at all! "

    The HD signal's still there... you just have to learn how to read between the lines.

    Yes. Go to a showroom and look at the displays. If you see some that have greater vertical resolution than the non-HD models, there you go. If you can't see a difference, then it doesn't make a difference.

    This is not a solution.

    At Best Buy and Circuit city I've seen lots of SD signals on HD displays. How on earth am I going to know if it's the set or the signal that's producing all those jaggies? Ask? At Best Buy? I might as well ask them to build a moon rocket while they're at it.

    Knowing the stats won't neccessarily guarantee you a better picture, but it is a better place to start.

    We all know that the 100W at 0.08THD in an 8-ohm load at 100-10,000Khz is the far superior amp.

    You don't care much for bass, do you? And most people find it difficult to listen to ultrasound all day.
