Glow Check: Is Your Screen HDR?
If your glow looks “meh”, it might not be you — it might be your screen. Here’s the fastest way to tell.
⚡ Create HDR ImageScreen Compatibility
- HDR Support: HDR-capable screens are required to see the glow visible.
- SDR Limitations: SDR screens show a normal image without extended brightness.
- Max Brightness: Full brightness is often necessary to activate the effect.
- Power Modes: Battery saving features often disable HDR capabilities.
- Format Check: The file must be the original PNG from Flashblind.
- Metadata Role: Metadata instructs the screen on how to render the brightness.
Brightness Settings
- Set to 100%: Keep brightness high to ensure the dynamic range is active.
- Avoid Auto-Dim: Automatic adjustments may reduce the visible impact.
- SDR Clamping: Low brightness may cause the screen to clamp to SDR levels.
- Viewing Environment: Darker surroundings enhance the perceived contrast.

FAQ
Why don't I see the glow?
Your screen may be SDR-only. SDR screens show a normal image. Ensure brightness is up.
Can I take a screenshot?
No. Screenshots strip glow data instantly, resulting in a standard SDR image.
Does editing preserve the effect?
Filters and editors strip glow data. Always use the original file.
Can I compress the file?
Avoid compression. It removes the brightness data required for the glow.
