Hi Cedric, and all

Panasonic have always been shifty about their bit depth.

You will note [from their spec sheets] The older models are 'equivalent' says to me 'dither'

The 50-BT300U they state 'TBD'.......What does that mean To Be Determined?

go figure

We only use the Pannas for the 'client' end of the room. Not for grading.

Apart from that they line up beautifully

I like them

5,120 steps (equivalent)

Hi all,

I calibrated a Panasonic TH50BT300 plasma yesterday and it' looked

very nice, managed to get spot on primaries and balanced greys (Rec709

settings, D65 white point). The only annoying thing  while grading is

that we get to see some kind of dithering on the subtel gradients

giving slight purple/green on on the greys that tend to be less

visible at what they call Normal color temp.

I wonder what other people using this one usually do, live with it or

go thru a LUT box to compensate for that.
