  • Resolution definition: Consumer 4K typically refers to UHD (3840×2160 pixels), a 16:9 format that’s exactly twice 1080p in each dimension (4× the pixels).
  • Cinema vs. consumer: DCI 4K (4096×2160) is used in theatrical workflows; most TVs and streaming services use UHD.
  • Other dimensions: 4K is one axis of image quality; color depth, gamut, dynamic range (HDR), and bit-rate strongly influence perceived quality.
  • Practical takeaway: “4K” alone is incomplete — in 2021, HDR (Dolby Vision, HDR10+), wide color gamut (BT.2020/P3), color depth (10-bit+), and bitrate determine the real experience.
