I'm not very good at the specifics, But I just had to be the first to say this is an excellent LCD. I Replaced my 19' Samsung with this 21' after searching HDTV sale best price & I've been Impressed by the picture. The much needed improvements needed over the LN19A450 were very much needed.

This is a third gen LCD; sound is a little better with adjustments, but still the same speakers (Use Exteral Speakers), picture is much better & with the adustable backlight feature makes the picture a much deeper, richer screen to view. It has all the hookups you'll need Except it only has 1-HDMI input. The Price is Right & Shipping is Free.
