Question because I do not understand it. I have at the reduce banding artifacts setting low/medium, should i tick "dont render frames when fade in/out is detected"?

well the LG OLED screens are more known for not dithering at all than doing heavy dithering.

I do tick "dont render frames when fade in/out is detected". If you are using easy settings for your GPU you do get 5 more medium debanded frames during the start of a fade with it not ticked but your GPU has to render 5 extra frames every time it detects a fade. This spike in load can cause a dropped frame or presentation glitch.

It definitely dithers to display shadows, like a plasma, you can see it quite easily.

Banding was a huge problem when setting it up but the banding does not mean it is not dithering, only that it is bad at it. When I set it to 6 bit in madVR the display's banding goes away pretty much entirely, even with default settings, and when set to 10 bit the banding is more common (I can see more of the steps). Banding test patterns all look very different at 6, 8, or 10 bit so I am sure the display is receiving different bit depths but it seems to have no idea how to go about displaying them without banding. Rounded looks much worse all the time, each step is visible and sharper, so it is not simply rounding anywhere. How do you get visible banding with a 16-bit gradient dithered to 10-bit on a 0-95 cd/m^2 display?!?

I had to tweak contrast and brightness a lot before finding settings that minimize the banding, which helped but still didn't eliminate it completely. I also have to be careful when watching real content and blaming banding on the display, some blurays I thought were fine turned out to have a lot of banding while others do not. If high debanding in madVR fixes it I blame the source but if it doesn't change it noticeably I blame the display. For my final calibration the contrast ratio was reported as 9528804659:1 by CalMAN, which does expose banding in the source.

All together this display does look very good, the black level and color saturation are both amazing, but banding is its major weakness.

Just a quick update re 3D, nVidia and MadVR.

The key to get this working seems to be to enable steroscopic 3D in the nVdia drivers while in 1080p, run the nVidia 3D Setup, and then set the desktop to whichever resolution/frame rate you actually use. My default is 4K@23p. MPC-BE/LAV/MadVR switch to 1080p3DFP to play the film automatically. They don't go back to 4K23 automatically, I have to leave MyMovies for that to happen. Sometimes they don't go back to 2D either, but in that case I only have to start playing a 2D movie.

The experimental custom rs tool Madshi made available recently has done wonders for my 2D bluray playback: I went from one frame repeat every 3-5 minutes to 1 frame drop every 2 hours or more, so very happy with that.

I still have to play a bit with the settings to find what works best with my new 1080 Ti, I really like the bluray to 4K upscaling using NGU Anti-Alias.

Overall super happy with the upgrade to the 1080 Ti from my HD7870.

Thanks again for all the help.

Thanks for the update on 3D!

I too have been very happy with NGU Anti-Alias.
