Lol, this is so fake, it makes me laugh. First, we have a company we never heard of in the TV world, second, foldable TV, so OLED I assume? Do you know any OLED panel maker making 3840hz panels? Next, 4k on a 150+ inch TV? Basically same ppi 1080p on a 75+ inch, that's disgusting for modern standards. Manufacturers are already at 8k for bigger sizes like that, and they say they are 4k?
Next point, what port are we using for content consumption? I don't remember any port supporting up to 4k3840hz, that would be hdmi9.9? Lol
Last point, higher refresh rate usually helps with faster movement, like soup opera effect, sport contents and gaming, which freaking gaming GPU can put put 3000+ fps on any game at 4k?
This is just a dumb concept product that will never see any light within the next 10 years, so let's not get our heads over it.
