LG C7 OLED TV 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 LG 55" C7 (OLED55C7P), and these should also be good for the 65" variant (OLED65C7P). These work well with everything except for gaming which requires a few extra tweaks, which are listed below.

General settings

The first thing we did was to turn off the 'Energy Saving' since we did not want to screen brightness to change automatically depending on the room lighting.

LG C7 Calibration Settings 2

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

LG C7 Calibration Settings 46

For calibration purposes, we adjusted 'OLED LIGHT' to 16 to reach our desired luminance of 100 cd/m². You can 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 then increased the 'Contrast' to 100 since it helped the calibration. We left 'Brightness' to 50, its default value

LG C7 Calibration Settings 5

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.

LG C7 Calibration Settings 6

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, you can use 'Gamma' 1.9.

LG C7 Calibration Settings 9

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.

LG C7 Calibration Settings 10

In the 'Picture Options' menu, we turned off 'Noise Reduction' and 'MPEG Noise Reduction', but you can turn on these features 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 if you have the good setting, when set wrong, blacks will look grayish instead of really deep blacks. We left turned off the 'Motion Eye Care' 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 you can read here to know more about those options.

LG C7 Calibration Settings 39

HDR settings

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 players may not detect that the TV can support the full HDMI bandwidth necessary for HDR content.

LG C7 Calibration Settings 47

When the TV detects HDR content, it will give you 5 'HDR Picture Mode' options. For movies, the 'Cinema' picture mode is the best option available since it will give you more control of the settings, similar to what you have access with 'IFS Expert (Dark Room)' with SDR content.

LG C7 Calibration Settings 52

Active HDR

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 C7, 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 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'.

SDR Gaming settings

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

LG C7 Calibration Settings 51

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. 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.

HDR Gaming 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. Some options won't be available to reduce the input lag.

LG C7 Calibration Settings 53

Miscellaneous settings

If you want to activate the Chroma subsampling (4:4:4) on the LG C7, 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.

LG C7 Calibration Settings 48

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.

LG C7 Calibration Settings 3

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.

What are the differences between PC mode and Game mode?
The major difference is that the TV can properly display 4:4:4 color in PC mode. "PC mode" on the C7 is when the input's icon is changed to PC. Any picture mode can be used when in PC mode, so you can be in the Game picture mode while in PC mode. All picture modes have the same low input lag in PC mode (same input lag as non PC Game mode); however some settings are disabled, such as TruMotion, Real Cinema and Noise Reduction.
19
When setting up HDR on the C7, do you use the same 'White Balance' and 'Color Management' settings in the Cinema picture mode?
Use the 'Warm1' color temperature, for HDR content we found it closer to our white point goal of 6500K (rather than 'Warm2' for SDR). But otherwise don't change any of the other 'White Balance' or 'Color Management' settings. Our calibration was done for SDR content and may not work well for HDR. We don't do a separate calibration for HDR because there is no reference calibration standard for HDR.

I have a C7 hooked up to my PC, when I put it in high dynamic range mode, PC icon, and game mode, it makes the screen really dark. No way to turn it up in TV settings or video card settings. Have 3.51.20 Software.
The C7P's HDR game and PC modes are indeed a bit dim. Unfortunately, there isn't a good way to solve this since LG locks the gamma setting while in HDR. It's unclear whether this is a bug or intentional, but if you want to keep the low input lag of the game mode, enabling dynamic contrast can help enhance the overall brightness.

I am interested in buying this television, but the pre-calibration results are giving me pause. Is it possible to achieve better White Balance dE and Color dE without the use of professional calibration tools? If not, can you please recommend an affordable calibration solution for personal use?
The out of the box calibration of the C7 should be good enough for casual use. Color accuracy isn't a large concern when buying TVs, if you use our recommended settings.

On our unit the white point was the worst aspect of its color accuracy, as the Warm 1 color temperature was a bit too cold but the Warm 2 was a bit too warm. Other units may differ from ours, perhaps Warm 1 or 2 will be more accurate for them. For quick calibration you could use a smartphone as a reference white point, if the smartphone is known to have an accurate white point. iPhones usually do, and you can check your phone's white point on Anandtech.com if they've reviewed it. You can try our white point calibration, but we don't recommend copying our other calibration settings as other units may differ significantly from ours. About cheap colorimeters, the Datacolor Spyder is a good one but it's still about $100 USD.

Hello, thanks for these detailed reviews. I am interested in PC input. Does this accept RGB (full) also, or does it only do YCbCr? Also, on my Pioneer plasma the PC input option locks the display and input both at 60Hz and no movie options are available (i.e. no 72Hz refresh and no 24p input). If I change the input from "PC" to "video" I get the options, and RGB input is still accepted, but it's not displayed at 4:4:4, it's downsampled to 4:2:0 for display. Could you confirm that no such limitations exist on this TV's PC input option? Thanks.
The C7 has no such limitations. RGB full range, 24 Hz, 120 Hz etc. are always accepted. When the input icon is set to PC all the picture modes display proper 4:4:4 color and have the same low input lag. However when playing HDR content the TV acts as though the input icon isn't set to PC, so 4:4:4 color is not properly displayed and only game mode has low input lag.

Do you know if these settings should reflect the same results on the B7 model? My understanding is that it uses the same software and panel but I am wonder if there any any differences that would make it perform differently.
Yes, the settings should apply to the B7 as well.

I was interested in buying the LG C7 but I saw that the E7 came with a Dolby Atmos sound bar. Is this something I can buy separately or would it be better to buy a home theater system to get a better Atmos setup? If so, what do you guys recommend I buy along with the C7 to match or exceed the audio of the E7?
You can probably buy a C7 and a better sound system for the price of the E7. We expect the E7 to have similar picture quality to the C7. Separate Dolby Atmos soundbars exist, such as LG's own SJ9. We don't have any recommendations for sound systems, but a sound system with dedicated speakers is often better than a soundbar.
