The Hisense 32" H4F (32H4F) can't be calibrated and we expect this to be valid for the 40" model (40H4F). Here we demonstrate the available settings that you have in the menu.
These settings apply to most types of content, except for gaming which requires a few additional changes, listed below.
One of the first things we did was disable all of the Auto Power Saving features, as we don't want the TV to adjust the image during testing.
For SDR content, we recommend choosing the 'Movie' Picture Mode, as it is the most accurate one out of the box, and allows for the most customization. We recommend setting Contrast to '45', Brightness and Color at '50', and Tint and Sharpness at '0' and Color Temperature to warm.
To make the image brighter in SDR, you should first select the TV brightness range in the TV picture settings menu to one of the 5 preset options and then adjust the Backlight on the Advanced Picture Settings depending on your specific viewing conditions. Changing this setting does not have any impact on the overall picture quality. The Brightness setting is a picture adjustment setting, and we do not recommend adjusting it.
From the base SDR, very few changes are required for a great gaming experience. When you start gaming, it is best to switch to the Game Mode to 'On', in order to get the lowest input lag and use the recommended settings for SDR.
Unlike TVs from most other brands, no special settings are required for PC use on the H4F. Just make sure you switch the Game Mode to 'On' to enjoy the lowest input lag.
