TCL 8 Series 2019/Q825 QLED Calibration Settings

For additional settings information, please consult the Common Problems and How to Calibrate pages.

We used the following calibration settings to review the TCL 65" Q825 (65Q825), and we expect them to be valid  for the 75" (75Q825) version as well. 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.

General Settings

Eco Settings

One of the first things we did was disable all of the auto power savings options, as we don't want the TV to adjust the image during testing.

SDR

For SDR content, there are five preset picture modes. We recommend choosing the 'Movie' picture mode, as it's the most accurate one out of the box, and allows for the most customization. From the Advanced Picture Settings menu, we recommend setting contrast to '100', brightness to '50', and sharpness to '20'. We also set Color to '45', and Tint (G/R) to '0'. Finally, we chose the 'Warm' Color Temperature.

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.

The Local contrast setting controls the Q825's local dimming feature. We recommend the 'High' setting, as the 'Medium' and 'Low' settings did not seem to do anything.

Image Enhancements

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 Dynamic Contrast. You should adjust these to your personal preference, though.

HDR

The above image is from the menu of the TCL R625. The menu of the Q825 looks identical.

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. We recommend leaving these settings to their default settings in HDR.

For HDR to work from external devices, HDMI 2.0 usually has to be enabled from the HDMI 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.

Make HDR Brighter

If you find HDR too dark, there is not much you can do without ruining the picture quality. You can try adjusting the Brigthness setting, but this will affect the picture accuracy and we do not recommend it. The image on the side shows the EOTF before any adjustments.

Motion Settings

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.

Motion Interpolation

The TCL Q825 has an optional motion interpolation feature, known as Action Smoothing. When you enable it you can add soap opera effect to the image, up to 60 frames per second.

Black Frame Insertion

The TCL Q825 has an optional black frame insertion feature, known as LED Motion Clarity. Enabling it results in less persistence blur, but causes noticeable duplications in motion.

Judder Settings

The TCL Q825 is able to remove judder from all sources, without you having to adjust any setting.

Gaming

This TV can enter game mode from any picture mode. When you start gaming, it should set Game Mode to 'On' to get the lowest possible input lag. Continue using the recommended settings for SDR or HDR. For HDR gaming, it's important to make sure that HDMI 2.0 is enabled for the input you are using.

When connected to supported gaming devices, including the Xbox One, the Q825 will automatically enter game mode when it detects a game is running, and it leaves game mode when the game stops.

PC Gaming

The Q825 will automatically detect when it's connected to a PC, and will automatically enter PC mode. If it doesn't detect your PC, simply change the input icon to 'Computer'.

White Balance Settings

Note: Although we calibrated our Q825 with the Gamma set to 2.0, we recommend leaving it at 2.2 for most users.

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.
