The term 2160p refers to the vertical resolution of the video frame. While the term "4K" is often used colloquially, 2160p specifically denotes Ultra High Definition (UHDTV), with a resolution of 3840 x 2160 pixels.

Let’s put the file Stranger.Things.S02.2160p.BluRay.x265.10bit.HDR head-to-head with Netflix's 4K stream.

| Feature | Netflix 4K Stream | The BluRay x265 10bit HDR Rip | | :--- | :--- | :--- | | Avg. Bitrate | 15-20 Mbps | 40-90 Mbps | | Color Depth | 8-bit (with dithering) | True 10-bit | | Dark Scenes | Blocky, noisy | Clean, filmic grain intact | | Audio | Dolby Digital+ (Lossy) | DTS-HD / TrueHD (Lossless) | | Offline Viewing | Expiration dates / DRM | Yours forever (digitally) |

Acquiring Stranger.Things.S02.2160p.BluRay.x265.10bit.HDR is only half the battle. Playing it is the other half. This is not a file for your iPhone or your grandmother's laptop.

If you have a decent 4K TV, HDR (High Dynamic Range) is more important than the resolution bump. Stranger Things seasons post-S1 are masterclasses in neon lighting and deep shadow work.
