===========================================================

SDR

Preset mode = Gamer 1

Brightness = 22 for 120 nits luminance, but set this to whatever you find comfortable for your viewing environment

Brightness level = Uniform for desktop usage and general apps. Could move this up to low/high perhaps for SDR gaming and multimedia if you want

Contrast = 70

Sharpness = 50

Gamma = Mode 4

Colour temp = Manual 0

RGB levels = n/a

6 colour = defaults

Calibrated ICC profile attached as well which is designed to be used in the native colour space mode, but will map the colour space back to sRGB for colour aware applications.

If you don't want to operate in the native gamut mode or use our calibrated profile, you could switch to the sRGB preset mode for full clamping of the colour space back to sRGB in all applications. No need to alter colour settings in that mode, just adjust the brightness to your liking.

AI features

AI upscaling = high. You might as well leave this on, it won't be active if it's not supported, although it's only really of value for 1080p 60Hz external devices. See our review(s) for more information

AI Scene Optimization = user preference, try it out and see if you find it helpful

AI Sound = user preference, probably useful to leave on

General

Smart energy saving = Off

Input compatibility version = DP 2.1, unless you experience any issues with older GPU's in which case align this to the DP version of your card.

HDR

Game mode - use either Gamer 1 or Gamer 2.

Gamer 1 makes darker games and scenes a little brighter and makes those more visible which is good, and colours are more natural looking.

Gamer 2 isn't quite as bright in dark scenes, although arguably more "accurate" in terms of EOTF tracking. It also has more vivid and saturated colours which you may like for certain gaming situations, although we preferred the more natural colours of Gamer 1 mode.

After setting the other recommended settings here in HDR, try them both and flick between them to see which you prefer.

Brightness = 100

Brightness level = High

Sharpness = 50, unless you want to over-sharpen it a bit perhaps

Colour temp = Manual 0 (for D65 white point)

Dynamic Tonemap = Off

Gaming

Note that if you're using an NVIDIA GPU it seems to remember G-sync activation separately for normal mode and dual-mode, so you might need to check you've got it enabled in both if you're going to use that.

Black stabilizer - adjust this to your liking, you can use it up to the max 100 even without raising the black point which is good.

Adaptive-sync = On (also enable G-sync/FreeSync from GPU control panel)
