"The advantage of active-shutter tech - according to Panasonic - is that each eye receives a 1920 x 1080p image"

but presumably at half of the refresh rate than the TV would otherwise be capable of delivering, not to mention the big clunky glasses.

One way or another, you have to deliver twice the information that a 2D set would deliver.

What you need is two full-HD TVs and a pair of Clockwork-Orange-style eye-braces to point each eyeball at the relevant set.

If you are going to have to wear glasses then why not just have a couple of mini hi res screens in those glasses??
