Do Plasma Desktop know the max brightness nits of my monitor in HDR mode?

Do Plasma Desktop assume that the brightness of my HDR monitor is at a certain number?
Every display has different peak brightness, how do Plasma display correct color and brightness in HDR mode on different displays?

Thanks for your questions about HDR! Here’s a breakdown of what we know about HDR and KDE Plasma 6.1:

HDR Brightness and Display Variation

You’ve rightly observed that different HDR monitors have varying peak brightness levels. KDE Plasma might make some general assumptions about a monitor’s capabilities based on the HDR standard it uses (e.g., HDR10). This can lead to inconsistencies in the perceived brightness of HDR content across different displays.

Color Correction and User Control

KDE Plasma 6.1 is still under development in its handling of HDR. While some color correction might occur based on the monitor’s reported information, there might be limited user control currently.

Finding the Best Settings

Here’s some good news: KDE Plasma 6.1 offers some HDR-specific settings you can explore to improve your experience:

  • SDR Brightness: This adjusts the brightness of non-HDR content displayed in HDR mode.
  • SDR Color Intensity: This controls the color saturation of non-HDR content for a more vibrant look in HDR mode.

Experimenting with these settings can help you achieve a more balanced HDR experience on your specific monitor.

Further Exploration

The KDE community is a great resource for troubleshooting and exploring advanced settings. Here are some suggestions for further exploration:

  • KDE Forums: Search the forums for discussions on HDR and Plasma. You might find others with similar monitor models who can share their experiences and settings.
  • Plasma Documentation: The KDE documentation might have up-to-date information on HDR settings and future developments in Plasma.
  • Community Discussions: There might be online communities or forums specifically dedicated to HDR technology. These can offer valuable insights and discussions on HDR calibration and fine-tuning across different display types.

By combining these approaches, you can improve your HDR experience in Plasma 6.1. While there might not be a perfect solution yet for every monitor, the community and ongoing development efforts can offer valuable guidance.

So it only base on HDR10? Or it can also base on something like Display1000?

I saw a blog post on another site, it seems to be able to know the brightness via EDID, I’m so happy to hear it, thanks.
