The problem is that no-one has really come up with the definitive spec for
what HD really is, its open to interpretation. Some panels that claim HD
Ready but only display 852 x 480 get away with it as they have HDCP on a
component or HDMI connection and scale the HD image down. Worse still there
are panels that just scale HD feeds and don't do HDCP and also make the
claim. This is misleading in my book. True HD panels must have at least 720
horizontal lines to display 720p (to-be the most common broadcasted feed)
and the better panels do 1080p although these are expensive at the moment.
Interestingly most recordings are done in 1080p and scaled down to 720p to
be broadcast (in the USA).
