HD is not all it appears to be
An absolute fact; Standard Definition Content is best viewed on a top end CRT based TV; High Definition is best viewed in 1080P which requires a HD signal source connected via an HDMI cable. As it is now only possible to purchase TVs that are optimised for HD the best solution for most viewers is to use a SD signal that is 1080P upscaled to the maxim resolution of the screen (e.g. Humax 9300T). This gives all programmes a nearish HD quality that looks much more pleasing to the eye. SD on a HD TV is very poor, have you ever wondered why shops never display flat panel televisions showing SD Freeview?
