We used the following calibration settings to review the Hisense 55" H6570F (55H6570F), and we expect them to be valid for the 43" model (43H6570F), the 50" model (50H6570F), and the 65" model (65H6570F).
For SDR content, we recommend choosing the 'Theater Night' Picture Mode, as it is the most accurate one out of the box, and allows for the most customization. We recommend setting the Contrast to '46', Brightness to '50', Color to '45', Tint to '0', and Sharpness to '8'. Brightness is an image processing option; we do not recommend changing this setting.
The backlight of the TV, as well as Dynamic Backlight Control, can be controlled from the Backlight sub-menu. We recommend the 'Off' setting for Dynamic Backlight Control so that the luminocity doesn't change according to the light conditions of your room. You should adjust the Backlight level to your viewing conditions. Note that this setting does not affect picture quality.
In the Advanced settings tab, we selected the 'Low' Color Temperature setting, as this setting is closest to our target color temperature of 6500K. We left Noise reduction and Digital noise reduction off, but if you are watching lower quality content it might be able to improve the picture a bit. Note that these settings can result in a loss of fine detail in some scenes.
HDR is automatically enabled for the native apps. When you start playing HDR content, a small HDR icon appears in the picture settings menu. Once you start playing HDR content, some of the settings change automatically. We recommend choosing the 'HDR Theater' Picture Mode, and leaving the other settings to their defaults in HDR.
For HDR to work from external devices, in the HDMI 2.0 format menu, the 'Enhanced format' option usually has to be enabled. Older devices may have compatibility issues if this option is left enabled, so it is recommended to only enable this setting for devices that require it.
The H6570F supports Dolby Vision, from native apps and with most external devices. As with normal HDR content, when you start playing Dolby Vision content, some settings change automatically. We recommend leaving these settings as-is do not copy our SDR settings over.
If you find HDR content too dim, unfortunately, there isn't much you can do. It can be improved a bit by setting Active Contrast to 'High', which results in a slightly brighter image, as shown in this EOTF.
From the base SDR and HDR settings, very few changes are required for a great gaming experience. When you start gaming, it is best to switch to the 'Game' Picture mode, in order to get the lowest input lag, and use the recommended settings for SDR or HDR. For HDR gaming, it is important to make sure that HDMI 2.0 format is enabled for the input you are using.
Unlike TVs from most other brands, no special settings are required for PC use on the H6570F. Just make sure you are using the 'Game,' Picture Mode, and that HDMI 2.0 format is enabled for the input you are using.
The following are the results of the white balance and colorspace calibration on our unit. They are provided for reference, and should not be copied as the calibration values vary per individual unit even for the same model and same size as the TV we reviewed due to manufacturing tolerances. If you want to try them you will need to enter all values shown, as all of them are active at the same time. If you end up with worse picture quality, simply reset them to the default values.
