Our pick Samsung S90D

Samsung S90D if the room is bright; LG C4 otherwise

Bright-room HDRSamsung S90DDolby VisionLG OLED65C4Smart platformLG OLED65C4
  • QD-OLED holds colour saturation better at high brightness — the edge in a sunlit room
  • LG C4 still wins on Dolby Vision support and webOS app breadth
  • At similar money the choice is room-lighting and content, not raw quality
