Xbox HDR System Calibration Settings

Before adjusting, make sure you have set the TV settings correctly.

For step 1, set the black level to minimum (0 clicks). If the image of the game seems too contrasty to you, then you can try increasing the step 1 value by few clicks right.

For steps 2 and 3 in HGIG mode of your TV, get the symbol to become invisible. Try to find data about the peak brightness of your TV on the site RTINGS.COM. Knowing the peak brightness of your TV, you can check the values: press the LB+RB+LT+RT buttons during step 1, 2 or 3 to see the actual brightness values in the upper right corner. 

If your TV always does tone mapping and this can't be turned off, then set it to a value of a few thousand nits.
