I suspect it really depends on the model of tv. My current Samsung won't let me zoom in a 4:3 letterbox image through the HDMI inputs. I can do it on non-HD channels though. I need to try the component inputs on this though. My five year old Sony DVD player has a nice zoom mode, but the onscreen "zoom" icon won't go away.

What I miss from my older LCD is the ability to do picture in picture side by side from two video inputs. It would make comparing two different copies of the same movie a lot easier. The current set can only do PIP from the tuner. That's progress?

I think the green tint is a 2004 change. Lucas might have been trying to match the computer displays elsewhere in the film, most of which were redone.

As for my avatar, it comes from the July 1975 issue of Analog Magazine. More than a few people think it heavily influenced the design of Chewbacca.

I suspect I saw that cover at some point in the 70's, as it seems to have subliminally influenced a character I created back in college!
