Thanks. How do I set dynamic range to limited ?

And also, what setting do you use on your tv for 3D please?

I have the same set up LG OLED65E6P with Zidoo X9S. Someone pointed it out in the past. LG’s are working good with AUTO and 12 bit. Samsung’s are better with 10 bits for banding.
In general LG all AUTO except for Dynamic Range set to limited.

 Limited dynamic range in Zidoo
Zidoo > Quick Settings > Display > Advanced Settings > HDMI Range Mode 16-235

As far as TV adjustments it is very wide subject. There are hundreds of pages with owners threads and even more with debates about LG motion handling and settings. OLED screens are very fast and 24fps film material looks juddery and strobing without interpolated frames. On the other hand LCD based screens (all non OLED) have blur on frame transitions helping with perceiving motion. There are very good postings on LG motion settings from @GlennTidbury.
Here is link to one of them but you can browse through this thread for many more:

Important is to update firmware to the latest. I'm on Korean version 5.30.30 on my North American OLED 65E6P. Latest firmware has a lot of improvements in motion handling. I think official NA version is 05.30.25 witch is good also.

I can share my settings but it depends a lot on personal preference (judder from 24fps film or soap opera effect from frame interpolation). LG E6 and G6 were probably the best 3D TV's ever build. I like 3D realism and I push it to the limit using frame interpolation. Only best quality 3D Blu-Rays or ISO files. Completely black room. My seating is about 8 to 10' away from 65" TV. Eye level should be just below center of the screen.
My TV is not calibrated. Most of the settings are default. Try not to change settings from default thinking it will give you a better image. Some of the settings will produce anomalies on the screen specially in 3D. I found it the hard way

Here are some of my settings:
Under General set the HDMI Deep Color to on for Zidoo port
Under Picture > Energy Saving Medium (this reduces maximum brightness of the screen, I don't need very bright in the black room)
                    > Aspect Ratio Original and Just Scan
Picture Mode - Standard or ISF Expert Dark Room (all will work when set up Standard is shown for simplicity)
Standard > OLED LIGHT 80
              > Contrast 95
              > Brightness 50 (this should be adjusted per movie as needed. Typically is from 48 to 52 to keep deep blacks without clipping or glowing)
              > Sharpness 10 to 15
              > Color 55
> Avanced Controls > Dynamic Contrast OFF
                             > Dynamic Color OFF
                             > Color Gamut (I have it Wide
                             > Super Resolution Low
                             > Gamma Medium
> Picture Options > Noise Reduction LOW
                          > MPEG Noise OFF
                          > Black Level Low
                          > Real Cinema On (it gets greyed out and disabled when TruMotion is used)
                          > TruMotion Clear (for all 3D good quality movies)

The only difference for regular 2D HD movies (not HDR) would be setting TruMotion to User and De-Judder 3 to 5 based on content and your liking. De-Blur stays at 0. It is only for 50 and 60 fps videos. TV keeps separate set of adjustments for 3D. You need to make all changes while 3D signal is on the TV.
Send me a PM if you need more info. This is Kodi / Zidoo thread  

Note: One more point. LG motion processor gets overloaded working with 4K screen and 120Hz refresh rate. You need to kill all background active apps in order to free resources to motion processor. Long push on home button and X them all out. On occasion if something gets stuck and not looking right changing deep color any HDMI ports will force reboot.
