We used the following calibration settings to test the 65-inch LG Gallery TV, but they're also valid for the 55-inch model. 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.
SDR
Below are the settings we used to calibrate the TV in SDR. We chose the Filmmaker Mode picture preset, as it delivers the most accurate image out of the box. All other picture quality settings were left at their defaults.
- Picture Mode: Filmmaker Mode
- Adjust Contrast: 95
- Black Level: 50
- Gamma: 2.2
- Black Level: 0
- Near Black Detail: 0
Brightness - Accuracy Preferred
The backlight settings should be adjusted in SDR based on your viewing conditions. These settings deliver the most accurate image in a completely dark room.
- Panel Brightness: 25 (100 nits)
- Panel Brightness: 57 (200 nits)
Brightness - Brightness Preferred
If you prefer a brighter image, adjust the Panel Brightness setting as needed.
- Panel Brightness: 100 (adjust as needed)
HDR
HDR is automatically enabled for native apps. Once you start playing HDR content, some of the settings change automatically. All other picture quality settings were left at their defaults.
- Picture Mode: Filmmaker Mode
- Adjust Contrast: 100
- Black Level: 50
- Auto Dynamic Contrast: Off
- Near Black Detail: 0
Brightness - Accuracy Preferred
Below are the settings we used for HDR10 in a dark room. These settings deliver the most accurate image, but also limit how bright the TV can get.
- Panel Brightness: 100
- Dynamic Tone Mapping: Off
Brightness - Brightness Preferred
Unfortunately, there's not much you can do to get a brighter image in HDR on this TV. Enabling Dynamic Tone Mapping can help in a few scenes, but most of the time it doesn't improve anything.
- Dynamic Tone Mapping: On
HDR White Balance
The following are the results of calibrating the white balance of our unit to 6500K in HDR using the 2-point method. These settings are provided for reference only and shouldn't be copied as the calibration values vary per individual unit. 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.
Gaming
When you start gaming, you can either switch to the 'Game Optimizer' Picture Mode or toggle the separate Game Optimizer setting to get the lowest input lag and enable advanced gaming features, including the game bar. No other changes to picture quality settings are needed. You can toggle ALLM and VRR support from the Game Bar menu. With ALLM enabled, the TV will automatically switch to Game Optimizer when you start playing a game.
Motion & Processing
Below are the settings we used for most of our motion and processing tests. Motion and processing can be subjective, so you should adjust these settings to your personal preferences. You might also need to adjust these settings depending on the source and specific content.
Judder
To remove judder on this TV, enable the Real Cinema setting. Even with this setting enabled, though, it can't remove judder from 60Hz sources, like most cable boxes or if you have the Match Frame Rate setting disabled on an external player.
Stutter Reduction Via Interpolation
Setting De-judder to '3' outputs a framerate equivalent to 30 fps, but unfortunately, it doesn't do much to reduce stutter in 24 fps content.
White Balance Settings
The following are the results of the white balance and colorspace calibration in SDR 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 size as the TV we reviewed, due to manufacturing tolerances. If you want to try them, you will need to enter all the 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.
