    When the ICC profile generated by DisplayCAL is applied, I notice that images and videos are less saturated (or lower contrast as well?). Is this normal? Are the following settings correct/optimal if I am displaying video through the calibration in dark viewing conditions?

    MONITOR SETTINGS
    Picture Mode: Expert1
    Backlight: 0
    Contrast: 95
    Brightness: 50
    Color: 70
    Tint: 0
    Dynamic Contrast: Off
    Color Gamut: Extended
    White Balance
    Color Temperature: Warm1
    Method: 2 Point
    Points: High
    Red: (Adjust as necessary)
    Green: (Adjust as necessary)
    Blue: (Adjust as necessary)
    Gamma: 2.4
    Color Management System (i.e. six-axis controls): (No changes will be made)
    Black level: Low

    That looks alright, but

    Gamma: 2.4

    Tone curve: Custom Gamma 2.4 Relative

    Any reason you chose 2.4 over the default 2.2?

    Color Gamut: Extended

    What make/model monitor is this? You’ll want to use a matching correction.

    The README says “So if you are displaying images encoded to the sRGB standard, or displaying video through the calibration, just setting the gamma curve to sRGB or REC 709 (respectively) is probably not what you want! What you probably want to do, is to set the gamma curve to about gamma 2.4, so that the contrast range is expanded appropriately, or alternatively use sRGB or REC 709 or a gamma of 2.2 but also specify the actual ambient viewing conditions via a light level in Lux, so that an appropriate contrast enhancement can be made during calibration.”, so I thought I should choose 2.4.

    For my use case (dark viewing conditions, playing videos and displaying images), what gamma should I choose?

    What make/model monitor is this? You’ll want to use a matching correction.

    It is a budget IPS monitor from LG which claims 72% “color gamut (CIE 1931)” (I think LG means “72% NTSC”?).

    In monitor settings, I can set “Color Gamut” to “Normal” or “Extended”. Which one should I choose?

    In color managed applications, the source (image) profile controls the tonal response (for the default colorimetric rendering), so calibration tone curve is irrelevant there. It affects non color managed applications though.

    In monitor settings, I can set “Color Gamut” to “Normal” or “Extended”. Which one should I choose?

    Profile both, then you know the gamut coverage.
