什麼是full hd?

Full HD - mean the display resolution must need 1920 x 1080

HD Ready - the display sure NOT 1920 x 1080 ... normally is 1366 x 768.

What the difference is... if you have the signal is 1920X1080, if you use HD Ready TV to display. it will should you the resolution 1080i (i = interlace) NOT 1080p (p= progressive). it mean the LCD use their technology to upscale the resolution.

For the difference... please see LCD TV 1080i 及1080p 的分別
