Conclusion: The Samsung HU8550 series of LED televisions is packed with features and despite some picture issues, it performs the best of the 4K panels we've tested. 1080p is still a better bet right now, but If you're set on a 4K TV, it should be at the top of your list.
Pros: Full-featured. Elegant, utilitarian design. 4K output is stunning.
Cons: Mediocre black levels. Colors run slightly cool. Poor input lag. Native 4K content is still rare.
Conclusion: If you’re going to put a TV as sizeable as 65-incher is in your home, you deserve a terrific picture, not just a big one. And the HU8550 delivers that premium picture quality, no matter the source’s resolution (VHS tapes notwithstanding, folks).
Pros: Best flat 4K TV Samsung makes, Uniformly high brightness, Great black levels, shadow detail, Snappy navigation and app loading
Cons: Reflective screen, Loses clarity and contrast off-axis, Some edgelight bleed
