Can I make monitor volume changes gentler near the quiet end?

For a monitor whose volume is controlled through DDC, adjust DDC value mapping skew for the volume control. This changes how the app's slider positions map to the monitor's volume values, so you can give more of the slider's travel to the quieter range.

Open Settings > Displays > [display] > Device Control > DDC Control > Configure Controls…, find the volume feature, and adjust its skew. Start at a quiet listening level and compare small changes. Returning the skew to the center restores the unskewed mapping.

The result depends on the monitor. DDC sends whole-number values, commonly in a 0–100 range, and the monitor determines how loud each value is. Reshaping the curve cannot create extra hardware steps between two adjacent values or guarantee an exact logarithmic loudness response. Several nearby slider positions can therefore produce the same volume.

If the problem is the amount changed by each key press, adjust Settings > Keyboard > Configure Steps for Range-Based Controls… as well. A logical range of 100 with a standard step of 1 requests one percentage point per press. Keyboard steps, mapping skew and the number of segments drawn in the OSD are separate settings. With a skewed mapping, one app percentage point need not equal one DDC integer. See keyboard step sizes.

Use the monitor's actual supported minimum and maximum for the DDC range. Enlarging those numbers does not add audio precision. This setting applies to the DDC volume control and does not reshape a different controller's native audio volume. See DDC ranged values.
