Is HDR 400 good or bad?

As we dive into the world of High Dynamic Range (HDR) displays, there are several levels of quality, and one of those is HDR 400. But the question remains – is HDR 400 good or bad? In this article, we’ll provide a comprehensive analysis of this display standard and its drawbacks.

DisplayHDR 400: A Middle-Of-The-Road Performance

DisplayHDR 400 is a mid-range standard for HDR displays, claiming to offer slightly better-than-SDR (Standard Dynamic Range) performance. At its core, it targets monitors that lack advanced local dimming features and deep blacks. In contrast to more advanced HDR standards, like HDR10+, this certification doesn’t guarantee a specific level of brightness, color gamut, or contrast ratio. This is why some claim HDR 400 is bad.

Limitations

1. No Guaranteed Performance: HDR 400 doesn’t come with an agreed-upon set of specifications, leaving room for varying interpretations. This disparity in performance might result in some HDR 400-monitors delivering a mediocre picture quality.
2. Lack of Advanced Technology: HDR 400 screens don’t feature advanced HDR technology, such as tone mapping, metadata support, or peak brightness adjustments.
3. HDR Rendering Limitations: The low-bit-depth of HDR 400 (10-bit for some models) might produce less vivid colors, inferior color accuracy, and narrower color gamut.

In Short

HDR 400 screens don’t deliver the impressive contrast, color accuracy, and vivid colors of better HDR standards like HDR 10 or HDR10+ due to its lower maximum brightness, lack of color space support, and non-standardized tone mapping and metadata.

Comparison of HDR 400 with Better HDR Standards

HDR400 (400 nits and above)

• Suggested, but not mandatory support for HDR
• Only peak brightness matters; others ignored
• Simplify gamma tone mapping, missing details
• Only slightly improved HDR image compared
