Improvements over the previous model Pro 4K

RTD1619 media processor

• Dune HD Pro 4K II is the world's first media player on the newest RTD1619 media processor – the newest, the most advanced and the most powerful media processor from Realtek.

HDR10+

• The media player supports not only HDR technology (supported by the previous generation of media players), but also the most latest and advanced HDR10+ technology from Samsung. In conventional HDR technology, the brightness range is set at the beginning of the film and does not change during the film, so completely dark and completely bright scenes may have insufficient detail. In the latest HDR10 + technology, the brightness range can vary from frame to frame, so the maximum picture detail is provided even in scenes that contain only dark or only light elements.

VP9 profile 2 and YouTube 4K HDR support

• The media player supports not only the old VP9 video codec (which does not support HDR), but also the newest VP9 profile 2, which supports HDR and which is used in YouTube for 4K HDR content. Most other media players do not support it.

+77% faster CPU

• The media player has a 6-core ARM A55 CPU – which is +77% faster than 4-core ARM A53 used in the previous model Pro 4K.

+50% faster GPU

• The media player has the new GPU Mali-G51 – which is +50% faster than Mali T-820 used in the previous model Pro 4K.

4 GB RAM

• This is 2x more than in the previous model Pro 4K, and gives better performance for the most heavy apps.

32 GB flash

• This is 2x more than in the previous model Pro 4K, and gives more space for most heavy apps and internal storage.

Android 9

• For Android applications, Dune HD Pro 4K II uses a newer Android version 9.0 instead of Android 7.1 used in the previous model Pro 4K. This provides better support for the newest Android apps.

2x USB 3.0 ports

• Dune HD Pro 4K II has two USB 3.0 ports. The previous model Pro 4K has only one USB 3.0 port.

Other key advantages over competitors

Best-in-class movie ISO/folder structure playback

• Realtek-based Dune HD media players have the best-in-class support for playback of movie ISO/folder structures, including full support for 4K, 3D, HD audio. Movie ISO/folder structures can be played from any source - local drive (USB, SATA) or network drive (SMB, NFS). A special engine helps to ensure smooth playback of the entire movie w/o any audio/video interruptions even when playing movies with complicated structure.

Flicker-free framerate/resolution switching

• Dune HD media players implement its own advanced flicker-free approach for automatic framerate and resolution switching, which performs video mode switching before the start of file playback (rather than after). Most other Realtek-based media players perform video mode switching after the start of file playback, which causes unpleasant flickering.

Professional-grade controls for video output parameters

• Advanced setup controls allow professional users and installers to fine tune the video output parameters in the best way for a particular setup. In particular, it is possible to configure what chroma subsampling modes should be used for each individual HDMI video mode. The majority of competing media player models do not have such controls.

Widevine L1 and premium video services

• Support for Widevine Level 1 DRM (the most advanced DRM level) makes it possible to watch premium online video services with HD and Ultra HD video quality. Media players w/o Widevine Level 1 support can only output Standard Definition video in such services.

A comprehensive movies encyclopedia provides the information about hundreds of thousands of movies with detailed descriptions, posters, cross-links between movies and persons, trailers, direct links to online video services, etc. Advanced file browser automatically recognizes movies.

Dune HD mobile app

• The unique Dune HD mobile app (Dune Control) for iOS and Android mobiles devices provides full access to all functions of Dune HD media player in a very convenient and powerful way.

Proven history of software updates during a very long period

• Dune HD is known for its reputation to listen to user's feedback and provide software updates for many years. For example, for some old models, software updates with additional functions are provided for more than 10 years already.
