Horizontal Resolution lines question for Plasma and LCD Displays

[v_squared123]

Hello

My question is what difference is there with displays that offer 900 lines of resolutions to 1000 lines and last 1200 lines? Other than the obvious diff in the number of lines, is there really a difference in the picture quality?

One good example i know of is the pioneer kuro which has 900 lines of horizontal resolution. Most plasmas right now have atleast 1200. I looked into Samsungs line of plasmas, they have between 900 and 1000 with motion enhancement on and off. Panasonic has 900 to 1200 with motion smoother off and on.

Does this really make or break content thats full HD or 720p? Just a thought i had because im looking for a new tv
