HDR signal
Pixy uses browser dynamic-range support where available. If the browser reports SDR, the page cannot confirm HDR playback capability.
Wide gamut matters
HDR often matters most alongside wider colour gamut and enough brightness. Pixy reports the gamut signal separately.
Settings can interfere
Operating system HDR settings, browser support, cables, external monitor modes, and battery settings can all affect what Pixy observes.
HDR capability is not HDR quality
Pixy can report browser-detectable HDR support, but it cannot measure peak brightness, local dimming, tone mapping, or contrast.
Use this checklist while Pixy runs
- Enable HDR in your operating system before testing.
- Use a browser with modern colour and HDR support.
- Check the cable and display mode for external monitors.
- Treat SDR detection as a signal to inspect settings, not proof that hardware lacks HDR.
- Remember that poor HDR can still report as HDR capable.
Questions people ask
Does HDR support mean good HDR?
No. HDR quality depends on brightness, contrast, dimming, tone mapping, and panel quality.
Why does Safari or Chrome differ?
Browser HDR support and operating system integration can differ.
Can Pixy measure peak brightness?
No. Peak brightness requires measurement hardware.
