To actually see the benefits listed in that filename, your hardware chain must support every link:

2160p 10-bit files have very high bitrates. If playing over a network, ensure you are using a wired Ethernet connection or a 5GHz Wi-Fi band.

Ensure your server is set to "Direct Play." If the server tries to "Transcode" a 4K HDR file to a lower resolution, the colors will often look "washed out" (tonemapping issues) and your CPU usage will spike.

A 4K TV or monitor that supports Dolby Vision . If your TV only supports HDR10, the file will usually "fall back" to standard HDR, but you won't get the frame-by-frame optimization. Playback Device:

Use MPC-HC with the MadVR renderer or the VLC Media Player (ensure it's the latest version for DV support).

This happens when you try to play a Dolby Vision file on a screen or player that doesn't support it. The player is unable to interpret the DV metadata.
