SDR setup

Use these settings if you want to run with the native colour space for a more vivid and colourful image. You can combine with our calibrated ICC profile which will clamp back to sRGB for colour aware applications though.

Game preset = Gamer 1

Brightness = 21 for ~120 nits, but set this to whatever you find appropriate

Contrast = 70

Sharpness = 50

Gamma = mode 2

Colour temp = Custom

RGB levels = 51, 50, 48

Six color = defaults

Black level = High

sRGB emulation

If you want to clamp to sRGB all the time for all applications, games etc then you can use the following settings. This is good for SDR content and improved colour accuracy, but it will look less vivid compared with the native mode.

Game preset = sRGB

Brightness = adjust to suit, but you can use 21 for ~120 nits

Contrast = 70

RGB = 50, 53, 47 gives a better white point balance

Gaming / Other

Response time = 'Faster' for 1000Hz gaming and if you're using VRR within a range of around 400 - 1000fps. You can drop this down to 'normal' if gaming at lower refresh rates, or if overshoot becomes distracting. Use 'normal' for consoles and fixed 60/120Hz devices

Overclock = enable this if you want to squeeze a little further headroom out of the refresh rate, then set your GPU to 1100Hz. You won't be able to use MBR Pro though with overclock enabled but otherwise it's probably useful to enable it and use it.

Motion Blur Reduction Pro = this can be useful for improving motion clarity in certain situations. It's of most value if you're gaming at lower refresh rates as it has minimal impact at 1000Hz. If your game or system can't push to the max frame rate range, you could enable this for some motion clarity improvements if you want.

VRR = On (extended mode) - unless you have any specific issues with VRR in which case you could switch to standard mode, but we didn't face any.

Black stabilizer = this doesn't raise black point in any mode so you can experiment with this for darker gaming and content. moving it up to 75 seems a nice balance between improving shadow detail, without over-brightening dark shades too much. Feel free to adjust to suit your gaming situations

AI Scene selection = turn on if you want it to switch modes for different content, but you'll probably want to leave it off if you're using our recommended settings and calibrated profile

Deep Black Pro = activates the very limited backlight local dimming. May perhaps offer some small contrast improvements in the right situations, but visually makes very little difference in real world content. Prob leave this off.

Smart Energy Saving = Off (assuming you want maximum luminance potential)
