3D TVs are any different then regular TVs?

[tibimakai]

I'm wondering about this, since I have picked up a while ago a Sony KDL46NX720, but I didn't have time to look at it.

I wonder if it might be a marketing thing, like "HD audio"

The only difference is the LCD panel is driven twice as fast (120Hz drive) which 95% of panels support already in the form of 120Hz motion enhancement. They also have an IR beam to sync the glasses. Total additional cost maybe $5.00.

This Sony has some kind of camera unit built into it also, at the bottom.
What is that for?
In the specs, there is nothing mentioned about that camera.

Possibly the "room leave" camera they had going a few years ago. It can turn the panel off when you leave the room, but keeps the sound going, to save energy. The camera detects your presence by looking at your eyes.

I can't believe that I have this TV and I haven't even looked at yet.
I still have the Sony 46EX400 and the Samsung 46A650 to repair first. We had some really hot temperatures around here and I can't work in the garage.
I'm also finishing up an i5 Acer laptop. Still have to figure out a Kenwood navigation unit's DVD drive if it needs any calibration if it's replaced with a new unit.

If it's too hot to work in a garage, it's hot enough to be potentially damaging to LCD panels. Ambient above 60C can cause some problems like mura from distortion of the backlight films.
