Intel is developing patches for its Linux graphics driver that will enable high dynamic range (HDR) on monitors connected via daisy-chained DisplayPort cables or docking stations. Until now, this functionality was unavailable, limiting image quality in multi-monitor setups. The patches would arrive with Linux kernel version 7.3, improving the visual experience for users with Intel hardware.
Kernel 7.3 patches bring HDR support to complex setups 🖥️
The patches focus on managing HDR metadata across daisy-chained DisplayPort connections and docks. Intel's i915 driver must correctly handle the brightness and color signal on each monitor in the chain, something that previously failed. The implementation requires adjustments in the kernel's display management layer so that HDR flows seamlessly between devices. Kernel version 7.3 is expected to integrate these changes stably.
Daisy-chain HDR: now your monitors won't fight over brightness 🎨
Finally, users with three daisy-chained monitors will be able to see explosions in HDR without the middle monitor turning green with envy. Until now, connecting a dock was like asking a group of monitors to share a pizza: there was always one that ended up without color. With these patches, Intel promises that all monitors will agree on the tones. Of course, make sure your kernel doesn't choke on its morning coffee.
