Core
True HDR-first rendering

What is VxGallery HDR?
VxGallery HDR is a dedicated gallery and media viewer built specifically for HDR-capable TVs. Instead of stretching a phone UI onto a 65" screen, it treats your TV as a serious display: HDR photos retain their highlight detail and shadow nuance, HDR videos are played with care, and your sources (local storage, USB drives, NAS shares, Synology FileStation and Dropbox) all come together in a single, TV-first experience.
Whether you are a photographer previewing work, a home cinema enthusiast curating a library, or simply someone who wants family memories to truly shine in the living room, it is built to make large screens feel intentional, not accidental.
Key capabilities
What makes VxGallery HDR different from a generic media viewer.
Core
Unified viewer for photos & video
One viewer, one consistent feel. Swipe through HDR photos, then hit play on a video in the same folder, with no context switches and no separate apps inside the app.
Core
Multi-source by design
Browse media from local storage, USB drives, SAF documents, SMB shares, Synology FileStation and Dropbox. The app takes care of the protocol differences; you just browse your library.
Core
Startup auto slideshow
Turn any local folder into a dedicated slideshow entry point. When enabled, launching the app can immediately start a fullscreen slideshow of your chosen album.
Refinements
Bookmarks, resume & favorites
VxGallery HDR remembers where you left off, not only for local files but across network sources too. Favorites and metadata help you quickly get back to what matters.
Refinements
TMDb-powered poster wall
For film collections, optional TMDb integration can fetch artwork and basic metadata, so your video folders transform into a cinematic poster wall instead of a plain file list.
Refinements
Subtitle & audio control that stays put
Subtitle language, style and audio track choices are remembered. Once you teach the app your preferences, you do not need to repeat them for every session.
Refinements
TV-native navigation
Grid density, focus handling, key-based shortcuts and list layouts are all tuned for TV remotes. You can comfortably drive VxGallery HDR from the sofa without fighting a phone UI.
Refinements
4K stills & performance aware
Large, high-resolution stills and heavy files are handled with care, using dedicated paths such as still-to-MKV conversion where appropriate to keep browsing responsive.
Refinements
Granular cache management
Thumbnails, network images, 4K still caches, TMDb data and Coil caches can be inspected and cleared. You decide how lean or aggressive the app should be.
Refinements
Internationalized from day one
Language handling is built in, with English, Traditional Chinese, Simplified Chinese, Japanese, Korean, Russian, German, French and Spanish available, and English as a safe fallback.
Refinements
Designed to be polite to your TV
Careful handling of HDMI audio capabilities, HDR support probing and safe pause logic helps avoid nasty surprises when switching content or toggling passthrough on complex setups.
Built for real living rooms
One app, three kinds of power users.
For photographers & creators
Turn your TV into a true HDR lightbox, without exporting "TV-safe" copies or dumbing your files down for mobile apps.
- Display HDR photos and high-resolution stills on a big panel without flattening highlights or crushing shadows.
- Use automatic slideshows to loop selected folders for client showings or studio waiting rooms.
- Support for network sources (SMB, Synology, Dropbox) so your "master" library stays on a NAS, not on the TV.
View your HDR DNG, HEIC, JXR and other HDR image files on an HDR-capable TV (requires the companion software Image to HDRMKV Toolkit).
For home cinema enthusiasts
A viewer that treats your TV like a cinema screen, not a phone in landscape.
- Play HDR video with proper tone and color handling, tuned for TV panels instead of mobile screens.
- Audio track and subtitle selection are remembered per title, so the next session just starts right.
- Optional TMDb poster integration can turn your library into a clean, cinema-style wall of artwork.
For detail-obsessed users
All the tiny things that generic players never bother to get right.
- Startup auto-slideshow from a chosen local folder, turning the TV into a living photo frame when idle.
- Per-item bookmarks, favorites and resume positions even across large libraries and network sources.
- Granular cache controls (thumbnails, 4K stills, network images, TMDb, Coil) when you want to tidy up.
Small details, big impact
The parts users feel every day, but rarely see in release notes.
4K images that Google TV normally can't show
Google TV's UI pipeline is limited to 1080p, but VxGallery upgrades still images to true 4K using GPU-accelerated scaling and hardware-encoded MKV frames, so your photos finally look 4K on a TV.
Startup auto slideshow
Choose a local folder once, and VxGallery HDR can automatically launch straight into a fullscreen slideshow whenever the app starts. Perfect for turning your TV into an always-on family wall or studio showcase.
Per-source intelligence
Local storage, USB, SMB, Synology (via FileStation), Dropbox and SAF: each source is handled with its own heuristics so browsing feels equally smooth, regardless of where your media actually lives.
Bookmark & resume with context
Bookmarks do not just remember positions; they carry extra metadata, favorites, and even protocol-specific hints, so resuming a movie from a NAS feels as reliable as resuming a local file.
Subtitles that actually respect you
Subtitle language, size, font, background and edge style are remembered, and external SRT/ASS files can be loaded when you need them, with no more digging through the same menu every night.
HDR support introspection
The app can probe your device's capabilities (HDR formats, WCG support, JPEG-R, 4K single-frame encoding) and present them in a human-readable way, so you know exactly what your setup can handle.
Careful with big files
Large stills and heavy video files are treated differently, with thresholds, smart loading indicators and a "still-MKV" path to keep navigation responsive even with huge photo collections.
SMB, unexpectedly fast
Custom-tuned streaming makes SMB feel nearly local. HDR movies around 80 Mbps run smoothly, and seeking stays snappy even on Synology NAS.
Web Upload from any browser
Transfer photos and 4K videos directly from your phone or PC into the TV. Just scan the QR code, open the page, and drop your files.
HDR formats, codecs & the stills pipeline
Format support that most TV apps never reach.
Expanded capabilities
HDR formats supported
HDR10, HDR10+, Dolby Vision, HLG, WCG, JPEG-R (UltraHDR), playable on supported displays, with automatic fallback when HDR is unavailable to ensure proper tone rendering instead of washed-out output.
Audio engines & codecs
Powered by an FFmpeg extension, enabling playback of DTS family codecs such as DTS-HD Master Audio, DTS:X, DTS-TrueHD, in addition to Dolby Atmos, Dolby Digital+, AAC, PCM and more.
HDR stills to TV format pipeline, built for photographers, creators and archivists
Companion workflow: Image to HDRMKV Toolkit
Batch-convert HDR stills (JXR, EXR, HDR, HEIC, DNG, JPEG-R / UltraHDR) into HDR10-encoded 4K MKV single-frame videos for smooth, TV-optimized playback. Download the companion app →
Why MKV single-frame?
Many TVs struggle to present large 4K+ stills smoothly. Converting a still into a one-frame MKV allows hardware-accelerated decoding (MediaCodec / FFmpeg), resulting in faster load, smoother slideshow playback and consistent HDR metadata.
