I really do feel that using HDMI2 output from the 93 WITH "Source Direct" as the output resolution to my 6010 Kuro, the PQ is slightly cleaner, & colour rendition seems better to me at least. I tested the gamut of the display using Calman 5 and the numbers where just fractionally better using HDMI2 vs HDMI1. I would have thought they would be the same.
I did some further testing using BOB PARISEAU'S FAMOUS "RATATOUILLE" TEST SCENE and those dark to light contours/gradations are even better on HDMI2.
Really happy with this find.
BTW motion resolution also seems much improved, definitely less judder. I know this one is for sure, as I tested scenes that I know had slight judder.
Again, no settings were touched on the Kuro or on the 93.
