Thank you for this extremely helpful and well organised guide!
I followed it and I am now enjoying 4K HDR playback on my Samsung Q9 tv from my HTPC.

Well, I'm glad you got some use out of it. Hope your HTPC remains stable and trouble-free.
You can continue to tinker with various settings in madVR, the GPU and Windows, but I find, the more you tinker, the more things tend to break. Sometimes it's safer to just watch movies.

Much thanks to Warner306 for this excellent guide. I'm setup with Kodi 18, MPC-BE, and madvr and overall everything is working well including HDR passthrough.
However, I keep having a small problem I'm hoping someone here can help with. I'm using a GTX 1060 (6GB version) with the 385.28 Nvidia driver on Windows 10 1903. No matter what I do, I cannot get RGB Full to stick in the Nvidia control panel. For reference, the GTX 1060 is connected via HDMI to a Denon x3400h AVR, then to a Samsung KS8000 TV. UHD color, color space settings, etc. are all set up correctly on all devices, with the intent of using RGB Full throughout the chain as suggested. The HTPC is "always on" and I typically leave Kodi running all the time.
I've been through all the refresh rates, setting them up as suggested - i.e. 12-bit color for 30 Hz and below, 8-bit for everything else with RGB at full dynamic range. When I set it, it will stay like that initially. I can launch Kodi and it sticks, play a movie using MPC-BE as external player, no problems - so far so good. It will even survive a reboot, no problem. madvr reports the correct bit depth and all looks good.
However, if I switch off the AVR and TV (leaving the PC on and Kodi running) and come back later, say the next day, and turn everything back on again, it's immediately obvious the color settings have been changed to limited without anyone touching anything. I can go back into the Nvidia control panel and re-select "Full" on dynamic range, click "Apply" and everything returns to normal. Also another interesting anomaly is that if I start watching any HDR content, it triggers a switch back to "Full" with no need to go into the Nvidia control panel! No matter how it gets switched back to RGB full, it will stay that way as long as I'm actively using it, but if I ever switch the system off and come back a few hours later, it reverts to limited again.
This is driving me nuts. Any ideas from anyone on how to resolve this permanently? What am I missing or doing wrong?

I installed DSplayer Kodi Madvr for LG OLED TV when playing HDR movie, the screen kept blinking. Could you show me how to fix it?

Can you post a screenshot of the OSD (Ctrl + J) during playback and post it here. And the name of your GPU and operating system.

For GPU 1080Ti , which power management mode is the best for madVR? Adaptive or Optimal Power ? I read conflicting opinions or is a subjective choice.

There is a simple way , not too demanding in the various steps to do , to create a custom resolution with madVR and nVidia GPU ? to be honest I would have found some guidelines , but, in my opinion, a little too laborious to put into practice.
