Why are HDR games so dark? An expert analysis
As a passionate gamer and creator focusing on the latest gaming tech, I‘ve been asked why high dynamic range (HDR) games often appear too dark. This deeper dive will uncover the technical reasons behind HDR‘s darkness, how to optimize visibility, and whether it‘s a necessary tradeoff.
HDR 101: The promise and challenges
First, what is HDR? HDR displays can achieve higher contrasts between the brightest highlights and deepest blacks. This expanded range allows more realistic lighting that better matches our eyes.

Implementations vary, but standards define HDR as reaching:**
- Black level: 0.05 nits
- Peak white: 1000+ nits
Compare that to standard dynamic range (SDR):
- Black level: 0.2 nits
- Peak white: 100 nits
So HDR has the potential to showcase 10x more contrast. But achieving this is complex, often resulting in overly dimmed images.
Why HDR crushes shadows
Here are the key factors driving darkness in HDR games:
1. Great contrasts mandate darker shadows

Pushing peak brightness higher while representing deeper blacks necessitates a wider gap between extremes. So very dark shadow areas are pushed down to increase separation from intensely lit highlights.
2. TVs max out settings by default
To best showcase high contrast, most TVs will jump to their maximum capabilities for backlight, contrast, color saturation and more when entering HDR.
But when ranges are already maxed out, you have little room left to boost settings to counteract crushing blacks.
3. Tone mapping can overcompensate
To fit the wide HDR data into a display‘s capabilities, a process called tone mapping adjusts brightness across scenes.
But algorithms often overcorrect, dimming the average image brightness excessively just to avoid clipping the brightest peaks.
Optimizing the balance
Luckily, many configuration options can help reclaim lost shadow detail while keeping HDR‘s stunning highlights:
In-game adjustments
Developers build in settings to override overly aggressive tone mapping and insufficient brightness.
Recommended game-specific settings:
| Game | Settings |
|---|---|
| Red Dead Redemption 2 | Peak brightness: 60% |
| Call of Duty: Modern Warfare | Brightness: 53 |
| Assassin‘s Creed Valhalla | Gamma: 1.8 |
Display configurations
Modern TVs allow extensive customization to correct HDR implementations:
Top 3 display brands for HDR flexibility:
- LG OLED
- Sony Bravia
- Samsung QLED
Using calibration test patterns, ensure backlight and grayscale tracking match content luminance levels.
System HDR slider
Consoles and Windows include an overall slider to balance brightness between HDR and SDR:

Set this higher if your display lacks punch on its own.
The controversial HDR darkness
Custom tuning provides more pop in shadows without overly distorting the expanded range. But some inherent darkness is part of HDR‘s value.
The ultimate goal is realism – matching our eyes‘ ability to distinguish details across high contrast scenes.
So don‘t expect or want completely even exposures under HDR. The tension between bright and dark is intended for immersion.
But well-implemented HDR strikes a balance where interactive visibility doesn‘t suffer, even if subtle shadow details remain darker.
The way forward
As more games embrace HDR‘s stunning lighting capabilities, consistency and control over intensity across all scenes will improve.
My advice as both a gamer and industry analyst? Embrace expanded contrasts with some targeted optimizations. The added realism, without excessive crushing of detail, makes the tradeoff worthwhile.
