We used the following calibration settings to review the Samsung 55" Q70T (QN55Q70T), and we expect them to be valid for the 65" model (QN65Q70T), 75" model (QN75Q70T), 82" model (QN82Q70T), and the 85" model (QN85Q70T). These settings should apply to most types of content, except for gaming or use as a PC monitor, which require a few additional changes, listed below.
One of the first things we did was disable all of the Eco Solution options, as we don't want the TV to adjust the image during testing.
For SDR content, there are four preset picture modes. We recommend choosing the 'Movie' picture mode, as it is the most accurate one out of the box, and allows for the most customization. From the Expert Settings menu, we recommend leaving the Contrast at '45,' and Sharpness at '0.' We also left Color at the default value of '25,' and Tint (G/R) at '0.' Finally, we chose the 'Warm2' Color Tone, as it was closest to our calibration targets. We set the Gamma to '2.2,' as that is closest to our calibration target.
To make the image brighter in SDR, you should adjust the Brightness setting depending on your specific viewing conditions. Changing this setting does not have any impact on the overall picture quality. Samsung has renamed the Backlight setting found on previous generations, and removed the previous Brightness setting.
As we aim for an image that is as close as possible to the content creator's intent, we disable most image processing options, including Contrast Enhancer. You should adjust these to your personal preference though.
HDR is automatically enabled for the native apps. When you start playing HDR content, a small HDR icon appears next to the picture mode on the quick settings menu. Once you start playing HDR content, some of the settings change automatically, including the Backlight, which increases to 'Max.' We recommend leaving these settings to their default settings in HDR.
For HDR to work from external devices, Input Signal Plus usually has to be enabled from the External Device Manager menu for the input you are using. Older devices may have compatibility issues if this option is left enabled, so it's recommended to only enable this setting for devices that require it.
If you find HDR content too dim, set Contrast and Brightness to maximum, set ST.2084 to maximum, and set Contrast Enhancer to 'Medium.'
Although we disable most motion enhancing functions for most of our tests, you should adjust these to whatever looks best for you. Some settings may need to be adjusted depending on the specific content you are watching.
Although we usually leave these settings disabled during most of our testing, you should adjust the settings in the Picture Clarity Settings menu to your liking, as different people prefer different levels of motion interpolation. If you want to enable motion interpolation, set Picture Clarity to 'Custom', and adjust the Judder Reduction slider to your liking. The LED Clear Motion setting controls the Q70T's Black Frame Insertion feature. Most of these settings will need to be adjusted depending on the specific content you are watching.
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 enable Game Mode from the General settings tab to get the lowest input lag and use the recommended settings for SDR or HDR. For HDR gaming, it's important to make sure that Input Signal Plus is enabled for the input you are using.
Like last year's QLEDs, the Q70T supports low latency motion interpolation, great for improving motion on low frame rate games. The options are almost identical to the Motion Interpolation settings. To enable motion interpolation in Game mode, enable Game Motion Plus, and adjust the sliders to your preference. The Judder Reduction slider adjusts the interpolation of low frame rate content (30 fps), and the LED Clear Motion setting enables the Black Frame Insertion feature.
The Q70T supports FreeSync variable refresh rate technology. There is no setting to enable, as it now turns on automatically when the TV detects a game being launched from a device that has VRR enabled.
The Q70T supports FreeSync when connected to a PC with a supported AMD graphics card, or with an Xbox One. Unfortunately, it does not support FreeSync with NVIDIA's new Adaptive Sync drivers, as NVIDIA's implementation only works over DisplayPort, which this TV lacks.
The Q70T will usually detect when it's connected to a PC, and will automatically enter PC mode, to ensure proper chroma 4:4:4 support. You can also manually enable PC mode by changing the input icon to 'PC.' In PC mode, some settings are disabled, including many picture settings, and there are only two Picture Modes: 'Standard,' and 'Dynamic.' For low input lag in 'PC' mode, Game Mode must also be enabled.
When watching lower resolution content, the upscaling method may need to be adjusted depending on the specific format. The screen position, zoom, and picture size can be adjusted from the Picture Size Settings sub-menu. During testing, we encountered a bug when in PC mode, where the image would be zoomed in too much. To fix this issue, set the aspect ratio to 16:9 and set Fit to Screen to 'On'.
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.
