SDR calibrated mode

For use with our calibrated ICC profile attached, configured to a 2.2 gamma, D65 white point and clamping the colour space back to sRGB for colour-aware applications.

Scenario mode = Standard

Brightness = 14 (for 120 nits, but set this at whatever you find comfortable and appropriate for your ambient light conditions)

Contrast = 50 (default)

DCR = off

Sharpness = 5 (default)

Gamma = Gamma 1

Colour temp = User

Colour space = Native

RGB = 49, 50, 49

If you don't want to use our calibrated ICC profile then you could also use the sRGB, DCI-P3 or Adobe RGB preset modes to work specifically with those colour spaces. They are nice and accurate, and will still give you full access to the brightness setting, although you will no longer have access to the colour or gamma controls. Just adjust the brightness to suit if you're using any of those modes, but don't combine them with our calibrated ICC profile as that's designed to be used with the 'standard' native gamut mode only.

SDR multimedia and gaming

You can also enable the local dimming setting in SDR if you want, but we'd only recommend this for gaming and multimedia, not for desktop apps/static content.

Local dimming = high (for the maximum contrast improvements). We would recommend only using this for dynamic content in SDR, not for general/desktop apps

Dark Field Bright Effect control = level 1 improves shadow detail in some situations, although it does raise black depth slightly but we think the trade off is worth it for dynamic content. Experiment, but we wouldn't go higher than level 1.

Response time = set this to 'fast' for 160Hz native mode, including in VRR situations. If you're using the dual mode and a fixed 320Hz (no VRR) you could bump this up to 'fastest', but at any lower frame rates the overshoot starts to become too obvious, in which case sticking with 'fast' mode is better. Note that if you ever use the DIC blur reduction mode, that automatically moves you back to 'normal' mode annoyingly, so you'll have to manually change it again after disabling DIC each time.

HDR

Local dimming = high (for the maximum contrast improvements).

Mode = GameMode
