i have a macbook, and plan on purchasing a plasma tv... somewhere around 42-50 inches. 1080i, possibly 1080p. right now i have my laptop plugged into a regular tube television using a regular yellow video cable and the needed adaptor. it looks like poo. i can't read text. video is decent though. using a hdmi or vga cable, what is the resolution i can achieve on a 1080i plasma? will text be legible, essentially making it a big honkin monitor?
