When you shop for a 4K QLED TV, “HDR” is one of the most common selling points—and one of the most misunderstood. Many product pages list multiple HDR formats: HDR10, HDR10+, and Dolby Vision, sometimes alongside HLG. To most buyers, they look like similar checkboxes. But in real viewing—especially streaming movies and modern series—HDR format support can influence how consistent, bright, and natural the picture looks from scene to scene.
Still, HDR formats are only part of the story. A TV can support every HDR format and still look “off” if settings or room conditions aren’t right. This guide explains what each HDR format does, when you’ll notice the differences, and how to set up your TV so HDR actually looks better—not darker, flatter, or weirdly over-processed.
HDR stands for High Dynamic Range. In everyday terms, HDR aims to show:
brighter highlights (sunlight, reflections, sparks, neon signs)
more detail in dark scenes (shadow texture, night scenes)
richer color (without losing detail)
Compared to standard SDR video, HDR can feel more “real” and dimensional—when it’s done well and matched to your room.
But HDR is not one fixed format. Different HDR standards handle the “instructions” for brightness and tone mapping differently. That’s where HDR10, HDR10+, and Dolby Vision come in.
HDR10 is the most common HDR format. It’s widely supported across:
TVs
game consoles
streaming platforms
Blu-ray discs
HDR10 uses static metadata. That means the content includes HDR “instructions,” but they don’t adapt scene by scene. The TV takes a single set of guidance and applies it throughout the video.
HDR10 can look excellent, but scene-to-scene consistency depends more on:
how the TV performs tone mapping
your picture settings
your room lighting
HDR10 is the “minimum HDR” you should expect on a modern 4K TV.
HDR10+ builds on HDR10 by adding dynamic metadata. That means the content can provide scene-by-scene (or shot-by-shot) guidance so the TV can adapt brightness handling more intelligently.
HDR10+ can improve:
consistency in mixed scenes (dark rooms with bright windows)
scenes that quickly shift from bright to dark
highlight detail that might otherwise clip or blow out
shadow detail that might otherwise look crushed
In other words, HDR10+ tries to reduce the feeling that HDR is “too dark” in some scenes and “too bright” in others.
Dolby Vision is another dynamic HDR format, and it’s widely discussed because many major streaming titles are mastered with Dolby Vision.
Like HDR10+, it can adjust guidance scene by scene, helping the TV map content to the display more smoothly.
You’re most likely to notice Dolby Vision in:
high-quality streaming originals
movies with lots of shadow detail and controlled highlights
content that contains challenging lighting transitions
But Dolby Vision isn’t magic. Its quality still depends on:
the TV’s ability to render highlights and maintain detail
your room conditions
correct picture mode and tone mapping settings
A common mistake is assuming “Dolby Vision support” guarantees “best picture.” It’s a valuable feature, but it’s not a shortcut around calibration and room reality.
You may see HLG (Hybrid Log-Gamma) listed as well. HLG is commonly used for:
broadcast HDR signals
certain live events
specific regional TV systems
If you watch broadcast HDR content, HLG support is useful. If you mostly stream, HLG might matter less day-to-day than HDR10/HDR10+/Dolby Vision.
Here’s the practical decision framework:
Prioritize:
Dolby Vision (common on many streaming titles)
or HDR10+ if your content ecosystem supports it heavily
Prioritize:
HDR10 (it’s everywhere)
Plus at least one dynamic format is a nice bonus.
Make sure:
HLG is supported
For most buyers, the “best” HDR setup is:
HDR10 as the baseline +
at least one dynamic HDR format (HDR10+ or Dolby Vision) +
correct TV settings and a room-aware picture profile
Even with the best HDR formats, people sometimes complain:
“HDR looks dim”
“HDR looks gray”
“Skin tones look strange”
“Dark scenes lose detail”
Most HDR complaints come from these issues:
Some HDR picture modes are tuned for dark-room accuracy. In a bright room, that can look underpowered.
Fix: create a “Day HDR” profile:
slightly increase backlight/brightness
keep contrast settings sensible (don’t crush shadows)
avoid extreme “Vivid” modes that break color accuracy
A TV might automatically switch to an HDR mode, but the default option isn’t always the best.
Fix: try a cinema/movie HDR mode for films and a brighter standard HDR mode for daytime.
Too much sharpening, noise reduction, or motion processing can make HDR look unnatural.
Fix: reduce processing. HDR content is usually already clean and detailed.
Many people assume they’re watching HDR when they aren’t.
The TV may show an HDR badge when HDR is active (HDR, HDR10+, Dolby Vision).
Some TVs show signal info (resolution + HDR type).
Some streaming apps label content as HDR/Dolby Vision—but that doesn’t always guarantee it’s playing in HDR if bandwidth or settings are limited.
Tip: If HDR never seems to trigger, check:
HDMI port mode (enhanced/high bandwidth)
device output settings (console/streaming box)
the streaming plan/content version (some services require higher tiers for 4K HDR)
HDR formats matter for movies more than games. For gaming, the most important factors are often:
stable Game Mode
correct HDR calibration (console tools)
VRR/ALLM and low input lag
a TV that doesn’t crush shadow detail (you need to see enemies in dark areas)
If you game often, treat HDR as part of a larger gaming setup—not the only feature.
If your site strategy is to educate buyers and then guide them to a model designed for modern mixed use, the “HDR formats explained” article is a perfect internal link bridge. A 4K QLED TV positioned with modern HDR support and strong everyday brightness is generally a practical match for real homes, especially bright living rooms.
For your internal linking:
HDR10 is the baseline and you’ll use it often.
HDR10+ and Dolby Vision can improve consistency because they adapt scene by scene.
But the biggest “HDR upgrade” in real homes usually comes from:
correct picture mode
a day vs night profile
controlled reflections and room lighting
avoiding over-processing
