Did you set black output offset to 0%? I think these artifacts are in the source and bright gamma makes them visible (also without any conversion active by novideo_srgb). Though...

I missed the crucial part in the title. :/ I think there is a misunderstanding though, as the issue reporter says he wants to achieve gamma 2.2, but apparently selects...

I wouldn't pay too much attention to synthetic test pictures that only work with certain display gamma settings such as sRGB curve and rather trust your colorimeter and DisplayCal if...

Valid question, I think also your gamma curve deviations in your measurement report are way too much off. Do your photographs represent well what you see? I find the sudden...

How does gamma curve look like in validation without novideo_srgb calibration/clamp active? Are there weirdly extreme deviations for darker parts? If so, check whether perhaps using that "increase near-blacks" cheat...

> In color managed applications the gamma curve doesn't matter anyways. Assuming a different gamma curve than was intended for a given content technically equals (visibly) worse delta results. It's...

Ok, then for whatever weird reason, indeed something seems to go wrong when novideo_srgb tries to apply calibration from the profile. Did you already try without VCGT calibration (gamma "as...

> Nothing is wrong, 100% output offset crushes black shades, that is exactly how it should work. Use 0% output offset or sRGB curves to not clip the first few...

On Windows, unfortunately only with novideo_srgb and dwm_lut. When display or whole system was suspended, Windows introduces banding with active VCGT (also with Radeons). It can also happen after some...

> You are seeing banding with VCGT even with dithering enabled? Yes. There is banding caused by -gamma correction applied via Windows calibration feature in color management UI (can be...
