LG UJ7700 LED TV Calibration Settings
Here are the following settings we've used to do the calibration of the LG 49" UJ7700 (49UJ7700), and these should also be good for the 55" variant (55UJ7700), the 60" variant (60UJ7700) and the 65" variant (65UJ7700). These work with everything except for gaming which requires some minor changes, which are listed below.
The first thing we did was to select the 'IFS Expert (Dark Room) since it was the picture mode that gave us the closest result to our calibration goals. We set the 'Aspect Ratio Settings' to 'Original' since we did not want our input to be stretched in any way. If you have some older lower resolution content that does not fill completely the screen, you could change it to a mode that stretches the original content to match the screen. We then set to 'Off' the 'Energy Saving' mode, so that the TV would remain the same no matter how bright the room is. Finally, the 'Eye Comfort Mode' was left off, since we do not want the color temperature of the TV to change by itself depending on the content played.
For review purposes and in our completely dark room, we adjusted 'Backlight' to 34 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 color accuracy, only the luminance of the display. We then increased the 'Contrast' to 90 since it helped the calibration. We left 'Brightness' to 50, its default value. Both the 'H Sharpness' and 'V Sharpness' were set to 0 since we did not want to add any oversharpness.
We left 'Color' to 50 and 'Tint' to 0, their default values.
In the 'Expert Controls' settings page, we turned off 'Dynamic contrast', 'Super Resolution', 'Edge Enhancer' and 'Color Filter'. We then set the 'Color Gamut' to 'Auto' since when set to 'Auto' The TV will change the 'Color Gamut' automatically to match the source. The gamma was changed to 2.2, since it is the gamma that we aimed for during calibration.
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.
In the 'Picture Options' menu, we turned off 'Noise Reduction' and 'MPEG Noise Reduction', but you can turn on these on 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 much more grayish or may be crushed. 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. The 'Real Cinema' option was turned off for the review process, but if you are watching a 24p movie via a DVD or Blu-ray players, then it must be turned on to have a judder-free experience (you can read more on our 24p playback test here). For the 'LED Local Dimming' depending on the test we were running, we try many different settings, from 'Off' to 'High' and we found that the local dimming feature is not that great on the UJ7700. We recommend turning it off completely since it darkens the screen too much and will change the look of the content you are watching. But in any case, you can try and test each setting and select the level of local dimming that you feel is the best for you.
The 'TruMotion setting is related to the motion interpolation and if you like the soap opera setting, you can set the setting to 'User' and adjust the slider to add the level of desired soap opera effect. Note that since this TV has only a 60Hz panel, the level of SOE is more limited than on a 120Hz TV.
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.
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. It is also best to change the color temperature to 'Warm1' since we found that in HDR, it was more precise than 'Warm2'.
SDR and HDR Gaming settings
To get the best input lag possible when gaming whether you are in SDR or HDR, 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 difference 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.
If you want to activate the Chroma subsampling (4:4:4) on the UJ7700, you need to set the 'Input Label' to 'PC' (from the input menu) for the HDMI port where your device is connected and be sure that the 'HDMI ULTRA HD Deep Color' is also turned on. You can read more on the subject here.
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.
