These are the recommended picture settings for the LG UJ7700 series sold in the US and Canada: the 49UJ7700, 55UJ7700, 60UJ7700 and 65UJ7700. The TVs use an IPS panel and support HDR. When they were released, HDR had only just become a common feature and there was still very little HDR content.
The values below will help you get a more accurate and natural picture than the factory presets. They are intended for a dark or dimly lit room.

What Each Setting Does
Expert (Dark Room): the most accurate picture mode, designed for dim lighting. In a bright room, try Expert (Bright Room) and raise the backlight.
Aspect Ratio – Original: shows the picture in its source proportions, without stretching or cropping.
Energy Saving – Off: automatic power saving dims the screen and changes brightness on its own.
Backlight: controls overall screen brightness. Adjust it to your room, since 39 is tuned for a dark room.
Contrast and Brightness: Contrast sets the white level, and Brightness sets the black level. Check them on a test pattern so that you don’t lose detail in bright or dark areas.
H/V Sharpness – 0: avoids artificial edge halos on a 4K picture.
Noise Reduction and MPEG Noise Reduction – Off: these filters smooth fine detail. Turn them on only for low-quality sources.
Black Level – Low: suits standard video sources. If you connect a PC that outputs full-range RGB, try High or Auto.
LED Local Dimming – Off: local dimming can raise contrast, but it may also cause uneven brightness in dark scenes.
TruMotion – Off: disables motion smoothing and the “soap opera effect”. For fast sports you can try a low setting if you prefer smoother motion.
Dynamic Contrast, Super Resolution, Edge Enhancer – Off: these add artificial processing, so the image stays closer to the source.
Color Gamut – Normal: keeps colors accurate for standard content; Wide tends to oversaturate.
Gamma 2.2: a common target for normal viewing.
Color Temperature – Warm2: on LG TVs this is typically the closest preset to the standard white point.
White balance: fine-tunes color neutrality across brightness levels, from dark grays to white.
