LG A2 OLED Calibration Settings

We used the following calibration settings to review the 65-inch LG A2 (OLED65A2), and we expect them to be valid for the 48-inch (OLED48A2) and the 55-inch model (OLED55A2). 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.

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, there are a few different preset picture modes available to choose from. The 'Expert (Dark Space, night)' Picture Mode delivers the most accurate image out of the box and allows for the most customization, so that's what we used for our calibration. 'FILMMAKER MODE' mode is a great alternative if you're a movie fan and want an accurate image. It automatically disables most of the TV's processing, but it also locks you out of most settings, so we don't use it for our calibration. If you aren't in a completely dark room, the 'Expert (Bright space, night)' preset is a bit brighter overall but less accurate.

From the Advanced Settings menu in the Brightness section, the OLED Pixel Brightness setting controls the luminosity. A setting of '23' is closest to our calibration target of 100 cd/m², but that's way too dark for most rooms, so you should adjust this to your viewing conditions and personal preferences. Changing this setting has no impact on the overall picture quality. The Peak Brightness setting helps increase the brightness, and we set it to 'High', but it also causes a variation in brightness between different scenes, so if it bothers you, leave it disabled.

From this menu, we set Adjust Contrast to '85', and we left the Black Level at '50'. A Gamma setting of 2.2 is closest to the 2.2 gamma we target for a moderately-lit room, but if you're in a bright room, you may want to adjust this. We left Auto Dynamic Contrast disabled, and the Video Range set to 'Auto'.

From the Color menu, we left the Color Depth set to '50', and Tint set to '0' as these settings are already the closest ones to the SDR calibration targets. We also left the Color Gamut set to 'Auto Detect', but if you prefer saturated colors, setting it to 'Native' will adjust SDR content to match the HDR color gamut of the display. From the White Balance menu, we chose the 'Warm 50' Color temperature. If you prefer a warmer or colder image, you should adjust this setting to your liking.

Finally, from the Clarity menu, we left Adjust Sharpness at '0'. For most of our testing, we also kept Super Resolution, Noise Reduction, MPEG Noise Reduction, and Smooth Gradation settings disabled, but you should adjust these depending on the content you're watching and your personal preferences. These settings can help improve the appearance of low-quality content, like from DVDs.

HDR is automatically enabled for native apps, and we suggest using the 'Cinema' Picture Mode. Once you start playing HDR content, some settings change automatically, including OLED Pixel Brightness. We left all settings in HDR to their defaults, as we don't attempt to calibrate HDR. For HDR to work from external devices, the HDMI Deep Color option usually has to be set to '4K' from the 'HDMI Settings' menu for the input you're using. Although rare, older devices may have compatibility issues with this setting. If your DVD player or older console isn't working properly, try setting this to 'Off' instead.

If you find HDR too dim, you can try enabling Auto Dynamic Contrast or Dynamic Tone Mapping. These settings can help produce a brighter image but are also highly dependent on the content.

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're watching or because of your personal preferences.

If you want to enable motion interpolation, set TruMotion to 'User Selection' and adjust the De-Judder slider to '10'. Unfortunately, the A2 doesn't have a black frame insertion feature like on other LG OLED models.

The LG A2 can remove judder from 24p sources, and you just need to enable Real Cinema.

From the base SDR and HDR settings, very few changes are required for a great gaming experience. When you enable Game Optimizer from the 'General' settings tab, the LG A2 automatically enables all game-related settings and switches to the 'Game Optimizer' Picture Mode for low latency when you start playing a game from a supported source, like a PS5 or Xbox Series X.

For HDR gaming, you should set HDMI Deep Color to '4K' for the port you're using; otherwise, you might have some issues. If Game Optimizer is enabled, the TV should do this automatically. Sadly, it doesn't support any VRR technologies to reduce screen tearing.

For an optimal PC gaming experience and proper chroma 4:4:4 support, it's important to set the input icon to 'PC' for the HDMI port you're using. You can do this from the 'Home Dashboard' menu. Depending on the format you're sending, it might also be necessary to set HDMI Deep Color to '4k'.

The LG A2 supports both ARC and eARC, allowing it to pass high-quality audio from a connected source through to a connected soundbar or home theater receiver. To use it, you must set the HDMI Input Format to 'Bitstream', Digital Sound Output to 'Auto', and then enable eARC Support if your device supports it. To send the audio to your speaker system, you must then set Use Wired Speaker to either 'Optical Out Device' or 'HDMI(ARC) Device' device, depending on your connection method.

From the AI Service menu, we ran the AI Acoustic Tuning wizard for our sound testing. It's part of the TV's room correction feature, which adapts the TV's sound equalization to suit your room. Depending on your room, you may have better sound quality with this enabled.

We disabled AI Sound Pro for our testing. We also disabled AI Brightness Settings, which adjusts the TV's brightness to the lighting of your room using a built-in light sensor, as we don't want the brightness to change with different content.

The LG A2 has a few accessibility features. It supports automatic closed captioning, high contrast mode, or even grayscale mode, just to name a few. There's also an option to disable the picture entirely, leaving the audio, which is great if you want to listen to music and don't need the screen on.

We disabled all the power-saving and automatic image modes because we don't want the TV to adjust the image during testing. For the A2, we set Energy Saving Step to 'Off' as we don't want the image changing during our tests.

Although we don't expect this to be an issue for most people, burn-in is a possibility. There are a few options in the General tab that you should be aware of to ensure you get the most out of your new TV.

The Pixel Cleaning menu allows you to run a complete pixel refresh cycle, which takes about an hour. You can set it to run a short pixel refresh automatically after every 4 hours of cumulative usage once the TV is turned off, or run it manually if you prefer.

The Screen Move setting, as the name describes, moves the entire image a few pixels to one side and gradually shifts it in a different direction over time. It helps reduce the effects of burn-in from very small elements, like fine lines in a game HUD. We recommend leaving this enabled, as the screen shift is not very noticeable unless you're using the TV as a PC monitor.

Adjust Logo Brightness automatically dims the area around a logo when it detects one on the screen. It can cause problems with some games if the TV detects a UI element as a logo and dims it, so we recommend setting it to 'Low'.
