Won’t ever happen.
Unfortunately, I don’t believe this is true. I don’t believe the Mali 400 in this configuration and the AllWinner VPU can handle 4K resolutions. The Mali 400 can probably just about manage a 4K2K framebuffer.
I’ve not seen a 4K demo, even with CedarX, which no one wants to touch with a 10 ft barge pole. It’s all dandy for them to say it does 4K, but there’s no real software out there to prove that. It’s like having a car that does 0-60 in 2.5 and tops out at 300mph, but runs on a fuel that you can’t find anywhere. You can’t disprove their claims, but they can’t really prove it either.
Really well marketed campaign though but the Raspberry Pi 3 is a better device than the Pine 64 though. Performance, software support, community and compatibility with third party peripherals are just better.
