Perhaps, but I see very little evidence of this from the SUHD. In the Movie mode--which is essentially Rec. 709--the red primary reference measurement is x0.637, y0.332 and the i1D3 measurement was...

Yes. When setting up an auto-cal session, you specify gamma. BT.1886 is one of the choices.

Quantum Dot

We just added a Quantum Dot mode for the Display 3 PRO. We used a Samsung SUHD display as a test display.

The JETI and AccuPel use the same FTDI drivers that the Lumagen uses, so they should be fine. I'll check to be sure.

Windows 10

FYI

I installed ChromaPure on Windows 10 and took measurements with both the i1D3 and the Spyder 5. I used the Lumagen as a signal generator. I encountered no problems.

I agree. A tripod, though not essential, is a very good idea. It helps to isolate the meter from the heat of the plasma screen.

You don't NEED one. The meter can be hung on the plasma much like you would with a desktop PC monitor. However, tripods are cheap--you can get a decent one for $20-- and it is a good idea.

Place the meter close enough to the lens to get about 500 with the diffuser in place, then measure. What are the black and white readings? Contrast should be between 20,000-50,000.

close enough to the lens to get a good black level reading but not so close that you overload the sensor.
