Description
MINIX U8K-ULTRA 8/128GB adopts Amlogic S928X-K with big.LITTLE ARM Cortex A76 + Quad-Core Cortex A55 Processor (64-bit) CPU and ARM G57 MC2 GPU. 8GB LPDDR4X + 128GB eMMC 5.1, 8K Resolution on board, Android AOSP 11 OS, upgradeable via OTA.
MINIX U8K-ULTRA is the next generation of AI media hub powered by Amlogic S928X-K processor. With the dedicated hardware video decoder, U8K-ULTRA is designed to decode multiple video formats, including but not limited to: AV1, VP9, H.265-10, AVS3 and AVS2.
The 8th Generation Advanced Amlogic TruLife Image Engine supports Dolby Vision, HDR10+, HDR, HLG and HDR Vivid processing, independent HDR re-mapping of video and graphic layer, motion compensated noise reduction and motion adaptive deinterlacer.
The dedicated hardware NPU allows the implementation of Neural Network, which enables AI-based picture quality enhancer (AI-PQ) and AI-based resolution upscaling (AI-SR) function. AI-PQ offers real-time scene detection based on picture contents, picture time and space characteristics; whereas AI-SR offers real-time picture detail upscaling of 2X (1080 content), 3X (720 content) and 4X (480 content), providing a much better upscaling picture quality than traditional non-AI based media players.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $48 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for MINIX products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
