Enabling HDR on Asus OLED Laptop Linux

[Cyber_Raven]

Good Evening,

Now that KDE Plasma’s HDR Support is good enough to be usable (in my experience, using this laptop with external monitors), I’d like to have the option of using the OLED Display on my Asus Laptop in HDR mode. The Laptop is an Asus Zenbook ux535LI, with a 4k OLED Touchscreen.

I’ve set the KWIN_DRM_ALLOW_INTEL_COLORSPACE=1 in my environment variables, but the HDR toggle is still not appearing in System Settings. kscreen-doctor -o doesn’t report the display as HDR capable, which it obviously is, as it’s OLED, and works perfectly fine for HDR in Windows, at least, last time I used Windows.

What else do I need to do to make this work? The display is connected to the integrated intel 10th gen iGPU.

Thanks

HDR only works on Wayland. If you’re in an X11 session the toggle won’t be there in any constellation.

That is what sounds like with setting the environment variable! As your display is an OLED and is working fine in Windows, it seems that KDE Plasma is not quite identifying the HDR capabilities for this configuration yet. Additionally, you want to ensure that your kernel is the current one for a few reasons; modern kernels have improved HDR display support.
