HDR videos require the display to push (compared to 200-300 nits for SDR). Driving an AMOLED or LCD panel at these levels consumes massive power, converting electricity directly into heat.

: To ensure support for all audio and video formats alongside HDR, it is highly recommended to install the MX Player Custom Codec

For occasional SDR content, it remains fine. For HDR10 or Dolby Vision media, users should switch to VLC, Just Player, or the device’s stock gallery player. The "hot" issue is not a hardware defect but a decoder inefficiency that has persisted across multiple MX Player versions (1.40.x to 1.85.x).

The application's ability to handle HDR content effectively is rooted in its sophisticated decoding engine.
