As of 12/1/15 this was by far the best 4K 55" TV for the price. Can't give it 5 stars because it's not in Logitech's database, so programming my existing universal remote was a chore. Also, using the provided remote, there is sometimes no response to button presses.
4K upscaling looks good when the source is 1080i, but it emphasized the fuzzy look of lower resolution sources, such as the archive footage sports programs are so find of.
SMART works well with my A/V unit and blu-ray player.
The display goes to black for several seconds when I am playing a recording from the Tivo Bolt and hit FF or REW. Still troubleshooting whether this is caused by the TV, the Tivo, the A/V unit, or SMART.
One other thing which earns it less than 5 stars is the stand. Instead of a centered stand which fits on a built-for-55" cabinet, the stand is a pair of V-shaped objects which attach to the right and left bottom edges, requiring a 4" wider cabinet top. Not an issue for those of you using a wall mount.
