Samsung QN900F 8K Calibration Settings

We used the following calibration settings to test the 65-inch Samsung QN900F 8K (QN65QN900FFXZA), but they're also valid for the 75-inch and 85-inch models. Our settings apply to most types of content, except for gaming or use as a PC monitor, which requires a few additional changes, listed below.

These settings are meant to provide 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, you can choose a few different preset picture modes. We used the 'Movie' Picture Mode because it's the most accurate out of the box and allows for the most customization. A Brightness setting of '6' corresponds to about 200 nits on our unit, which is our target for a moderately lit room, but you should adjust these settings depending on your viewing conditions. For our peak brightness test, Brightness was set to maximum. Below are the settings we used for SDR. All other settings were either disabled or left off.

• Picture Mode: Movie
• Brightness: 6 (200 nits)
• Contrast: 45
• Gamma: 2.2
• Color: 25
• Color Tone: Warm2
• Color Space: Auto
• Shadow Detail: 0

HDR is automatically enabled for 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. Below are the settings we used for HDR10. All other settings were either disabled or left off. If you're having any issues with HDR content, make sure Input Signal Plus is enabled.

• Picture Mode: FILMMAKER MODE
• Brightness: 50 (Max)
• Contrast: 50 (Max)
• Contrast Enhancer: Off
• HDR Tone Mapping: Static
• Color Tone: Warm2
• Color Space Settings: Auto
• Local Dimming: High
• Gamma: {ST.2084} -1

The TV supports HDR10+ from native apps and external devices. As with normal HDR content, when you start playing HDR10+ content, some settings change automatically. Since we don't specifically test HDR10+, we don't have exact settings for it, but they should be the same as our HDR10 settings.

The following are the old results of calibrating our unit's white balance to 6500K in HDR using the 2-point method. We don't publish the values we used for our new 20-point calibration.

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.

From the base SDR and HDR settings, very few changes are required for the best gaming experience. When you start gaming, it is best to enable Game Mode to get the lowest input lag. The rest of our gaming settings are identical to our regular settings for SDR or HDR. For chroma 4:4:4, you must have the input label set to 'PC' and Game Mode turned on.

To make eARC work, HDMI-eARC must be set to 'Auto,' and Digital Output Audio Format should be set to 'Passthrough.'

For our upscaling test, we set Sharpness to '8.' Sharpness processing was calibrated with no over-sharpening for low-resolution content.

This TV automatically removes 24p judder from all external sources and from the internal apps.

For information on any other settings or features that fall outside of the scope of our testing, please refer to the user manual found at the bottom of Samsung's webpage for the TV.
