I should note that this is with the backlight at 100.
I feel like I have some other model of this TV. I wonder if they went ahead and used a different panel from their newer 3D 70". Everything is remarkably improved. Granted it does appear I have a very recent build. I should have taken a pix of the box and info from that.
Do you watch at 100? I'd go blind!
While I'm glad you like the new set, keep in mind a lot of emotions at play when you get something new making you think it is SO much better. Unless both are calibrated to the same settings it is really tough to compare. Otherwise the brighter one will always look better.
