  • Vivid clarity , but . . . .
    by Expected Better Colors

    on December 7, 2019

    Picture is super clear even vivid you could say , but I can't seem to get the colors and tint correct. My 12 year old Vizio seems to have way better color. Red looks pink. When I add color it goes overboard and becomes almost neon and unrealistic. Back it off and it becomes dull and flat. Tried at least 7 or more times to get it dialed in and just can't.

  • Much better as espected
    by Kibofa

    Besides the sharp screen and excellent colors I'm positively surprised by the many features WebOS is offering. The remote control is amazing, I'm using it to control my NVIDIA Shield and Blue Ray player as well. Only have problems to find my volume and channel up/down buttons in the dark (wish it was light colored instead black). For the rest, best TV I ever owed! I hope more apps will be added soon (like ESPN, Kodi and Tidal). Love it!
