I am a bit confused about hi def capabilities. I keep reading about dpi's etc. The question I have is this. I have a 36" philips crt tv, 36PW9607c, that has pixel plus. Now, I've read how 'pixel plus' doubles the number of pixels and how it increases the vertical lines by a third, does this mean it would be capable of displaying hi def pictures? The tv I have just now displays a fantastic picture and I have not seen any lcd or plasma screens to challenge it. i would really hate to replace the tv for a panel with an inferior picture just for the sake of going HD.
