Projection TV Vertical Scanning Lines (Native Mode)?

Question

I'm looking at a RCA 52" Wide Screen rear projection HDTV RCA Television and was comparing it to another (twice as expensive JVC brand) television of the same size and type (but possibably not of like quality).

The RCA television has Vertical Scanning Lines (Native Mode) of 1080.

The JVC television has Vertical Scanning Lines (Native Mode) of 720.

What do the vertical scanning lines do for the picture quality? I would think the more lines the better the picture. If this is correct, the RCA, at half the cost, would be the better buy......am I thinking right?

Which of these two televisions are the best and why in your opinion?

RCA 52" Widescreen Rear-Projection HDTV R52WH77 and,
JVC 52" Rear-Projection HD-ILA HDTV with TV Stand HD527BP7

Seems not too many people know much about this subject.....or it's too boring. But, it's a legit question if you're in the market to buy an expensive large screen television....and I've found most sales folks don't know the answers either.

Answer 1

Any television that can't display 1080 lines of resolution is not High Def. It is Enhanced Def.

A signal with 1080 lines of resolution will be compressed down to 720 lines on the JVC. That's JVC's way of saving manufacturing money, making more profit, and confusing the consumer. If the TV can't do NATIVE 1080, I wouldn't buy it.
