If you're shopping for a smart TV in Europe in 2026, HDR (High Dynamic Range) is arguably more important than resolution. While 4K determines how sharp the picture is, HDR determines how good it looks — with brighter highlights, deeper blacks, and richer colors. But not all HDR is equal. This guide breaks down Dolby Vision, HDR10+, HDR10, and HLG so you can choose the right refurbished smart TV for your needs.

What Is HDR and Why Does It Matter?

HDR expands the range of brightness and color a TV can display. A good HDR TV shows details in dark shadows and bright highlights simultaneously — something standard dynamic range (SDR) TVs cannot do. In 2026, nearly every 4K smart TV sold in Europe supports at least HDR10, but premium formats like Dolby Vision deliver a noticeably better experience.

HDR10 — The Universal Baseline

HDR10 is the industry standard. Every HDR-capable TV, streaming device, and 4K Blu-ray player supports it. It uses static metadata, meaning one set of brightness and color parameters applies to the entire movie or show.

• ✅ Supported by every HDR TV on the market
• ✅ Open standard — no licensing fees for manufacturers
• ⚠️ Static metadata = less precise than Dolby Vision or HDR10+
• 📍 Found on: All refurbished 4K TVs from €199 and up

Dolby Vision — The Premium King 🏆

Dolby Vision is the gold standard for HDR. It uses dynamic metadata that adjusts brightness and color scene by scene — even frame by frame. Netflix, Apple TV+, Disney+, and most 4K Blu-rays use Dolby Vision as their primary HDR format.

• 🏆 Best picture quality — supports up to 10,000 nits brightness (future-proof)
• ✅ Dynamic metadata adjusts every scene for optimal contrast
• ✅ Supported by LG, Sony, TCL, Hisense, Philips — not Samsung
• ⚠️ Requires licensing fee — slightly more expensive TVs
• 📍 Best on: Refurbished OLED TVs and premium QLED models

HDR10+ — Samsung's Dynamic Alternative

HDR10+ is Samsung's answer to Dolby Vision. It also uses dynamic metadata but is royalty-free, making it cheaper for manufacturers to implement. Amazon Prime Video is the biggest streaming service using HDR10+.

• ✅ Dynamic metadata — scene-by-scene optimization (like Dolby Vision)
• ✅ Royalty-free — keeps TV prices lower
• ✅ Supported by Samsung, Panasonic, TCL, Hisense, Philips
• ⚠️ Less content than Dolby Vision — mostly Amazon Prime Video
• 📍 Best on: Refurbished Samsung QLED TVs

HLG — Broadcast TV's HDR Format 📡

HLG (Hybrid Log-Gamma) was developed by the BBC and NHK for live TV broadcasts. Unlike streaming HDR formats, HLG doesn't use metadata — it's backward-compatible with SDR TVs. European broadcasters like BBC (UK), ARD/ZDF (Germany), RAI (Italy), and France Télévisions use HLG for sports and live events.

• ✅ No metadata needed — works on any HDR TV automatically
• ✅ Backward compatible with SDR TVs
• ⚠️ Limited to broadcast content — not used by streaming services
• 📍 Useful for: European sports fans watching live 4K HDR broadcasts
