Main differences compared to the Pro 8K Plus model: no support for 8K and 4Kp120, lower CPU power, 4GB RAM instead of 8GB, no Wi-FI 6, fixed PCM sampling rate when playing music.
Replacement for the well-known Real Vision 4K models
This model can be used as an affordable replacement for the discontinued Dune HD Real Vision 4K and Real Vision 4K Plus models. This model has almost all the features of the Real Vision 4K models except for support for the outdated BD3D technology and support for music playback at the original PCM sample rate (use the 8K model if you need this feature). In addition, this model has several advantages over the Real Vision 4K models: AV one codec, more flexible video zoom options, decoding of any HD audio format into multi-channel PCM, support for 20 TB+ USB hard disks, larger built-in storage of 64 GB, newer Android 11 and other improvements.
AV one video codec
Media player supports the new AV one video codec, which can improve video quality by up to 50% without increasing the video bit rate (or requires up to 50% less bit rate for the same video quality). This new video codec is already used by YouTube and will become increasingly important for compatibility with various video services and content sources.

☀️ VS10 Video Processor – The advanced VS10 video processor engine ensures maximum image quality when playing back all types of content (SDR, HDR, VS10) with all types of video output signals (SDR, HDR, VS10). In particular, it improves the quality of conversion between VS10, HDR and SDR. This is also beneficial when using Media Player with TVs that do not support VS10, including plasma TVs, and especially when using projectors
⭐ Full support for VS10 formats -VS10 is supported for all common formats and all common profiles (P5, P7 MEL and FEL, P8)
🎵 Media player can output all HD audio formats to HDMI in bitstream pass-through mode. Also, media player can decode all HD audio formats to multi-channel PCM (up to 7.1 channels)
👍 The entire housing as a heat sink for super-efficient, noiseless cooling – In Pro Vision 4K implements the best passive cooling approach, using the entire metal housing as a giant heat sink. Heat is transferred very efficiently from the processor directly to the metal housing via a special heat transfer element
🖥️ Automatic Frame Rate/Resolution Switching – The media player can automatically adjust the output frame rate and resolution based on the content being played. This helps to ensure completely smooth video playback and to utilize the best path for video resolution upscaling (resolution upscaling done by the media player or by the TV)
🏎️ Dune HD Android Playback Accelerator Technology – This technology intelligently manages the resources of the Android operating system to minimize the impact of the Android operating system on the media playback engine, ensuring smooth and high-quality video and audio playback
📲 Dune HD mobile app – The Dune HD mobile app (Dune Control) for iOS and Android mobile devices provides full access to all the features of the Dune HD media player in a very convenient and powerful way. It completely replaces the standard IR remote control, allows browsing and selecting media content directly on your mobile device (the menu displayed on the mobile device mirrors the menu displayed on the TV screen), and includes the “Now Playing” section for convenient control
