AMD has released patches for its AMDGPU driver on Linux that add support for gamma curves 2.4 and 2.6, standards used in cinema and television for more precise contrast and color. Until now, only gamma 2.2 was available, common on PC monitors. With this update, AMD graphics users on Linux will be able to watch movies and series with color fidelity closer to the creator's intent.
Technical details of the implementation 🎬
The patches will be integrated into the Linux kernel v7.3, within the AMDGPU color management subsystem. The addition of gamma curves 2.4 and 2.6 allows for finer calibration in video playback environments, correcting color deviations in dark rooms or controlled lighting. The driver can now apply these correction tables directly from the hardware, reducing CPU load and improving latency in HDR or SDR content playback with studio precision.
Finally, Linux stops looking like an Instagram filter 🎨
Until now, watching a movie on Linux with AMD was like looking at it through a foggy window: the colors looked like they came from a 90s editing tutorial. With gamma 2.2, dark tones looked as if painted by an octopus with expired watercolor. But don't worry, with gamma 2.4 and 2.6, Darth Vader will no longer look like an elderly man with a hangover. Finally, we can cry over a series without blaming the graphics driver.
