Improvements of the VT60 over the VT50
The VT includes numerous picture and feature advances over the 50 series.
One of the improvements is a shorter peak firing time for 2013 models.
In 2012 models it was 1/2500
In 2013 it's a 3000 Focus Field Drive or 1/3000
This creates better motion sharpness and permits more gradations of black to white.
The VT60 is spec'd at 30,720 steps, up from last year's VT50's 24,576.
The VT60 panel includes a new red phosphor for deeper (less orange) reds.
VT60's image had better contrast , brighter whites, and deeper blacks.
There is a DCI color mode for a wider color gamut.
