A:Answer I had the C9 before getting the C2. C2 has better blacks, u will immediately notice the blacks are much better.I also noticed the clarity,colors and contrast in Dolby vision content and HDR is better in the C2 especially Red. The motion is definitely better, in fact the C2 has the best motion in a TV so far. It is buttery smooth. I also have a Sony A90j and the C2 is better in motion of fast moving objects.Also if you use a soundbar , the Earc is better compatible. One big problem I had with the C9, If u watch movies from an external bluray player or streaming box, previously on my C9 , the 4k content was dimmer and the colors were washed out. The C2 looks much better and the colors don't wash out. I have no regrets upgrading and the difference is noticeable.
