Seems like they all have same panel problem.

You can find more when you google ''model name'' problem or something like that.
It's known problem and have been discussed this thread too.
Seems like it doesn't support 32bit colors and only 24bit max.
''Supports UHD Resolutions up to 3840x2160p at 60Hz with 24 bit color and 4:4:4 color sampling''
OK. I was interested to 40inch model 40cx700e because its super cheap only 540€ and cheapest UHD TV that support 3D. But if it's have that problem then I'm not interested it anymore and looking for some better 3D TV-s and wait next year models. I plan use 3D for gaming with Tridef 3D or...
Thank you for the feedback.
Did your cx700 had same problem in 3D and what size cx700 do you use?
''TX50CX700B didn’t deliver full HD 3D resolution: the horizontal alternating black and white single-pixel lines simply merged into a solid grey block, suggesting a loss in vertical resolution.''
JU6400 40,48 and 55 use VA panel maybe these bigger ones use IPS panel. Most here use these 40 and 48'' so they are still VA.
Edit: My bad, EU JU6400(USA JU6500) and USA JU6400 are different. Seems like USA JU6400 doesn't support 4:4:4 60hz.
