Hisense U6/U6N Calibration Settings

We used the following calibration settings to review the 65-inch Hisense U6N (65U6N), and they're also valid for the 55-inch (55U6N) model. The 75-inch model (75U6N) uses an ADS Pro panel, so our calibration settings don't apply to that size, but the general picture settings will be very similar. The 85-inch model runs version 11 of the Google TV OS and is missing settings found on the other sizes, so our settings don't apply to it. 

These settings are meant to provide you with a starting point; they're not meant to be copied 1:1. They provide the most accurate image in a moderately lit room, but you should adjust them to match your personal preferences and viewing conditions.

For SDR content, there are a few different preset picture modes you can choose. We used the 'Theater' Picture Mode because it's the most accurate out of the box and allows for the most customization. 

There are a few settings you can adjust on the Picture settings page to optimize the image to your preference. From the Brightness settings menu, the Brightness setting controls the intensity of the backlight. We set Brightness to '47' as that's the closest to our target of 200 cd/m², but you should adjust this to your viewing conditions and personal preferences. Changing this setting has no impact on the overall picture quality.

We set the Contrast at '45' and left Active Contrast disabled. Most of our testing was done with Local Dimming set to 'High,' but if you find the zone transitions distracting, you should set this to a lower setting. As we aim for the most accurate image possible, we left Dark Detail disabled for our testing. We also left the Black Level setting at '0,' the most neutral setting. We set the Gamma to '2.2,' as that's also closest to our calibration target for a moderately lit room. If you find the TV crushes details in shadows or boosts shadows too much, you should adjust these settings to your preference.

In the Color settings tab, we set Color to '50' and Hue to '0' and chose the 'Warm1' Color Temperature because it's closest to the target color temperature of 6500K. You should adjust that setting to your viewing conditions. We also left the Color Space set to 'Auto,' so the TV doesn't appear oversaturated when playing SDR content.

In the Clarity settings tab, we left every setting disabled, as they can cause a loss of fine details in higher-quality content.

HDR is automatically enabled for native apps. When you start playing HDR content, a small HDR icon appears next to the picture mode on the quick settings menu, and some of the settings change automatically, including Brightness, which increases to 'Max.' We left all the picture settings at their defaults in HDR, except for Color Temperature, which we set to 'Warm1,' but you should adjust them to whatever looks best. In HDR, the 'Filmmaker' Picture Mode delivers the most accurate image overall, as it best tracks the PQ EOTF. This ensures that most content is displayed at the brightness level the content creator intended.

With most sources, HDMI Format has to be set to 'Enhanced Format' for HDR to work. 

The following are the results of calibrating the white balance of our unit to 6500K in HDR. They are provided for reference and shouldn't be copied as the calibration values vary per individual unit, even for the same model and size as the TV we reviewed, due to manufacturing tolerances. If you want to try them, you'll need to enter all values shown, as all of them are active at the same time. If you have worse picture quality, simply reset them to the default values.

The Hisense U6N supports Dolby Vision from native apps and external devices. As with normal HDR content, some settings change automatically when you start playing Dolby Vision content. The 'Dolby Vision Dark' Picture Mode is the most accurate, and the 'Dolby Vision IQ' Picture Mode optimizes the content according to the level of ambient light in the room.

Although we disable most motion-enhancing functions for most of our tests, you should adjust these to whatever looks best. Some settings may need to be adjusted depending on the specific content you are watching or your preferences.

If you want to enable motion interpolation, set Motion Enhancement to 'Custom' and adjust the Judder Reduction and Blur Reduction sliders. You should adjust these settings to your preferences, and you may need to adjust them depending on the specific content you're watching.

To remove 24p judder from any source, set Motion Enhancement to 'Film.'

From the base SDR and HDR settings, very few changes are required for a great gaming experience. When you start gaming, it's best to switch to the 'PC/Game' Picture Mode to get the lowest input lag and use the same settings for SDR or HDR. You can also enable Instant Game Response for the Auto Low Latency Mode so that the TV switches into Game Mode when you play a game from a compatible device. We disabled High Refresh Rate Mode, as it negatively impacts the TV's input lag performance.

Unlike TVs from most other brands, no special settings are required for PC use. Just make sure you're using the 'PC/Game' Picture Mode and that you set HDMI Enhanced Format to 'Enhanced Format' for the input you're using. These settings are required for low input lag and for chroma 4:4:4 support, which is important for text clarity.

The Hisense U6N supports eARC passthrough on HDMI 3, so you can pass high-quality audio to a compatible receiver. It supports both Dolby Atmos and DTS:X audio formats. It's best to leave eARC on 'Auto' and set Digital Audio Out to 'Pass Through.'

The Hisense U6N has a few accessibility features, and the settings are all available in the Accessibility section. You can enable Captions, High Contrast Text, and Text to Speech, to name a few.

We disabled all energy saving settings so that the TV doesn't turn off during testing, but you can adjust this to your liking if you want the TV to turn off on its own.
