Hisense U6/U6K Calibration Settings

We used the following calibration settings to review the 65-inch Hisense U6K (65U6K), and we expect them to be valid for the 55-inch (55U6K), and 75-inch (75U6K) models.

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 overall, but you should adjust them to match your personal preferences and viewing conditions.

For SDR content, you can choose a few different preset picture modes. We used the 'Theater Night' Picture Mode because it's the most accurate out of the box and allows for the most customization. The 'Theater Day' Picture Mode offers a slightly brighter image, but the difference is minimal, and the image is less accurate.

We set the Backlight Level to '52', but you should adjust the Backlight Level to your specific viewing conditions, and changing this doesn't have any impact on the overall picture quality. 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.

There are a few settings you can adjust on the Picture settings page to optimize the image to your preference. We set the Contrast to '36', Brightness to '50', Color to '47', and Tint to '0'. The Brightness setting is different from the Backlight Level setting because it affects the picture quality, and we don't suggest changing it. We also left the Sharpness setting to its default value during calibration, which is different than our recommended setting of '10' for upscaling.

In the Advanced Settings tab, we chose the 'Low' Color Temperature because it's closest to the target color temperature of 6500K. We left Noise Reduction, Digital Noise Reduction, and Active Contrast disabled as they can cause a loss of fine details in higher quality content. We also left the Color Space set to 'Auto', so the TV doesn't appear over-saturated when playing SDR content.

In Calibration Settings 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 this setting to your preference.

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 Backlight Level, which increases to 'Max.' We left all the picture settings at their defaults in HDR, except for Color Temperature, which we set to 'Low', but you should adjust them to whatever looks best. In HDR, the 'HDR Theater' 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 tested, 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 end up with worse picture quality, simply reset them to the default values.

The Hisense U6K supports Dolby Vision from native apps and most external devices. As with normal HDR content, some settings change automatically when you start playing Dolby Vision content.

Although we disable most motion settings for most of our tests, you should adjust these to whatever looks best. Some settings, like motion interpolation, may need to be adjusted depending on the specific content you're watching.

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 may need to adjust them depending on the specific content you're watching.

The Hisense U6K automatically removes judder from any source. You don't need to change any settings for it to do this.

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 'Game' Picture Mode to get the lowest input lag and use the same settings for SDR or HDR. For most recent consoles, set the HDMI Format to 'Enhanced' for HDR gaming. You can also enable Instant Game Response for the Auto Low Latency Mode so 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. The GameZone Settings menu allows you to adjust a few game-specific settings, such as increasing Black Level and White Level in your games.

Unlike TVs from most other brands, no special settings are required for PC use. Just make sure you're using the '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 U6K supports eARC passthrough on HDMI 4, so you can pass high-quality audio to a compatible receiver. It supports both Dolby Atmos and DTS:X audio formats. For DTS-X passthrough, set Digital Audio Out to 'Pass Through' and set it to 'Dolby Digital' or 'Auto' for all other formats.

The Hisense U6K 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.

Google TV has an Ambient Mode available to display your Google Photos or pictures of art if you want the TV to display a slideshow while you're not actively using it. You can even control the slideshow speed.

We disabled Energy Saver 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.

The included remote has a built-in mic for voice control, and the remote needs to be connected to the TV via Bluetooth to work. If the voice control isn't working, ensure it's connected via Bluetooth in the Remotes & Accessories page of the settings menu. The TV has a built-in microphone, and there's a switch to turn it on.
