LG B7/B7A OLED Calibration Settings

The following are the calibration settings we used to review the LG 55" B7 (OLED55B7A), and these should also be good for the 65" variant (OLED65B7A). These settings work well with everything except for gaming which requires a few extra changes, listed below.

First, we turn off the 'Energy Saving' since we do not want to screen brightness to change depending on the room lighting.

In the 'Aspect Ratio Settings' tab, we selected the 'Original' 'Aspect Ratio' with the 'Just Scan' option set to 'On' so that our HDMI input would be automatically matched to the screen without needing to change the 'overscan' setting from the source output setting.

We turn off the 'Eye Comfort Mode' since we do not want the TV to change the color temperature automatically depending on the content.

We then selected the 'IFS Expert (Dark Room)' picture mode since it was the picture mode that was the closest to our calibration goal.

For calibration purposes, we adjusted 'OLED LIGHT' to 17 to reach our desired luminance of 100 cd/m². You should adjust it to match your room environment. For a brighter room, this will need to be increased. Not that this does not affect the colors, only the luminance of the display. We set the 'Contrast' to 100, 'Brightness' to 50, its default values.

We adjusted both the 'H Sharpness' and the 'V Sharpness' to 0 because we did not want to add any sharpening. 'Color' was left to 50 and 'Tint' to 0, both their default values.

In the 'Expert Controls' settings page, we turned off 'Dynamic contrast', 'Super Resolution', 'Edge Enhancer' and 'Color Filter'. We set the 'Color Gamut' to 'Auto' since when set to 'Auto' The TV will change the 'Color Gamut' automatically to match the source.

We also set the 'Gamma'  to 2.2 as it helped to reach our calibration goal, but if you find that the blacks are crushed in some video content, you can use a lower gamma setting or if you find that the TV is clipping in the white (losing detail in the white regions), you can use a higher gamma setting.

In the 'White Balance' settings, we selected the 'Warm2' from the 'Color Temperature' settings since it was the 'Color Temperature' the closest to our calibration goal. Again, if you find the color to be too red or yellowish, you can use a different color temperature

In the 'Picture Options' menu, we turned off 'Noise Reduction' and 'MPEG Noise Reduction', but you can turn on these features a different level if you are watching older low-resolution content, as it may help reduce visual noise and compression artifacts. We set the 'Black Level' to 'Low' to match our source 'Output Dynamic Range'. If you are not sure that the setting is correct, when incorrect, blacks will look grayish instead of really deep blacks.  'Motion Eye Care' was turned off since we did not want the TV to change the brightness of the TV automatically depending on the displayed scene. For the 'Real Cinema' and 'TruMotion' settings, these relate to the 24p playback and motion interpolation you can read here to know more about those options.

First thing to do is to turn on 'HDMI ULTRA HD Deep Color' for the HDMI port where you intend to connect your HDR UHD Blu-ray players (or video games console if you are using it as a Blu-ray player), as some external device may not detect that the TV can support the full HDMI bandwidth necessary for HDR content.

When the TV detects HDR content, it will give you 5 'HDR Picture Mode' options. For movies, the 'Cinema' and 'technicolor Expert' picture mode are the best option available since it will give you more control of the settings, and they both have almost the same accuracy.

The 2017 LG OLED TVs now support HDR with 'Active HDR', which is similar to HDR10+ or HDR10 with dynamic metadata. This feature analyses the content frame by frame in real time to adjust the HDR tone mapping curve. This has the advantage of displaying each scene with an optimized HDR effect, as opposed to the HDR with a static metadata, where all the movie was using the same tone mapping curve, resulting in some scene sometimes being too dark or too bright or simply not exposed correctly to have the best possible HDR effect.

To activate this feature on the B7A, you need to go in the 'Expert control' tab. In the 'Expert Control' tab, you will need to set the 'Dynamic Contrast' to 'Low'. The low setting turn on the 'Active HDR without the 'Contrast Enhancement. We usually don't like to add any unnecessary image processing and this is why we are proposing to use the 'Low' setting here, as the 'Contrast Enhancement' would modify the content in a way that was not intended by the content creator. If you want to test this extra feature, then the 'Medium' setting set the 'Contrast Enhancement' to Low and the 'High' to 'High'.

Note that 'Active HDR' does not work when the TV is in 'Game' 'HDR Picture Mode' or in 'PC' Mode, so we recommend setting the 'Dynamic Contrast' 'Off' under those conditions.

To get the best input lag possible when gaming, you need to set the 'Picture Mode' to 'Game'.

Once the 'Game' picture mode is selected, some options won't be available in the setting pages since the 'Game' picture mode disables most of the image processing to give better input lag. Under game mode, the color temperature setting is now a slider giving you a different control from colder to warmer, and you can adjust to your liking. The gamma selection is also a bit different, giving you the option from 'Low' to 'High2'. In both cases, adjust these to your preference. For the rest of the available settings, you can follow our general settings.

For HDR gaming, simply turn on 'HDMI ULTRA HD Deep Color' for the HDMI port where you intend to connect your video game console or PC and select the 'Game' 'HDR picture Mode' to have the best input lag possible. Note that when in game mode, the color temperature control is not exactly the same as in other picture modes. We found that the setting 'W45' was the closest to our desired target of 6500K color temperature, but you can adjust it to your liking.

If you want to activate the Chroma subsampling (4:4:4) on the LG B7A, you need to set the 'Input Label' to 'PC' for the HDMI port where your device is connected. This setting is available via the 'Input' menu.

From the main 'Picture settings' page, there are the 'OLED Panel Settings'. Inside there is the 'Pixel Refresher' function and the 'Screen Shift' settings. 'Pixel Refresher' is the function that will clear any image retention or other screen issues that can happen when the TV is left turn on for a long period of time. This function needs at least one hour to run and will only start once the TV is turned off. This usually takes care of any image retention. The 'Screen Shift' is a feature that will slightly move the screen at regular intervals to prevent image retention. We recommend to turn on this feature.
