I got my LG 65C9 two days ago. I had no idea Kodi would look so terrible playing any 4k HDR mkv files. I have a GTX 1050 Ti in my Win 10 PC. I played a few mkv's via the USB port on the LG and it looks spectacular.
Many of the threads I find are very old about Kodi and HDR. I see lots of talk on madVR but I see some of the Kodi devs suggesting things have changed and you don't need to run dsplayer/madVR. So I have no idea where to start, what to do.
What can I do to get Kodi to play HDR without a lot of hassles? Is that possible?

So I installed Kodi DSplayer edition and madVR. I am using Avatar 4k HDR mkv as my test. When I play the movie on a USB drive plugged directly into the LG TV the colors/clarity are beyond stunning. With DSPlayer, it's just ok. The colors are bland and it's not too sharp. I'm not sure where to start. I tried changing to HDR passthrough instead of letting madVR make that decision, it was a slight improvement. I tried changing the gamma settings with ctrl-S options and it does nothing.
Under properties in madVR and in the picture menu in the LG. Set the Black Level on the TV to High and madVR to RGB 0-255. Same with the GPU: RGB 0-255.
The colors should be nearly identical if everything is working correctly.
I guess I'm confused where I should be making changes. Kodi has options and also I have the ctrl-S popup madVR options. What should Kodi be set to for Video Render, Manage Settings? (I have set to Load and Save DSplayer database)
In the Picture menu on the LG I don't have a black level for High. I do have a HDMI ULTRA HD Deep Color option.
Pressing control-S, madVR was set to RGB 0-255, where do I find the GPU setting?
Also Direct3D presentation, I changed that to DX11 (it was on 9) and now I get full oversaturated HDR colors. The skin tones are ok but probably a tad too strong. What should Direct3D be set to?
Ok, finally it's working well. Thank you for Onkyoman for pointing out the issues, that LG article on rtings.com really helped.
I still feel the LG internal media player is better but Kodi is close now. The main problem was my HDMI port was not set for PC. When I changed that the colors got corrected.
FYI, not sure how many know this but the LG media player is network friendly. I was able to configure my Synology NAS with their media server to work with the LG TV. It works very well and for anyone that does not use Kodi this is a nice alternative.
I would still use the other video modes if possible. It should only be a matter of getting the correct video levels on one of the video modes. Using PC mode might cause a slight difference in color compared to the internal player. I think the two should be very close.
My new receiver arrived today. My old was not 4k compatible. So since I programmed the HDMI port on the LG as 'PC' can I have other devices like my STB go into that 'PC' HDMI port? I was assuming I would have all HDMI go to the receiver first and then one cable to the LG.
A color space conversion could mean that you haven't set up the Pioneer receiver correctly for HDMI passthrough, you don't have the correct HDMI cables at both ends or the receiver is auto-detecting the PC and doing a color space conversion.
I haven't looked at the manual for your AVR, so I don't know how to configure it for 4K HDMI passthrough. It could be under inputs where you set the label for each source, but I don't know.
Your HDMI cables must be rated to carry an 18Gbps signal. They should indicate that they are compatible with 4K UHD content.
The color space conversion means the video levels are incorrect at the receiver. You need a chain of video levels from the PC to the AVR to the TV that ends in the same video levels.
If Black Level on the TV is set to High (0-255), you need to set all of your devices to RGB 0-255. If Black Level on the TV is set to Low (16-235), you need to set all of your devices to RGB 16-235 or YCbCr 16-235.
On the PC, you can get RGB 16-235 in two different ways.
The options that give you correct video levels are described here:
I called Pioneer, 100% useless tech support and unfriendly jerk to top if off. Insisted it's the cable without hearing or wanting to know any details.
So off to BestBuy I went and bought a RocketFish 4ft HDMI cable 4k Ultra HD and HDR. It's labeled a Premium Certified Cable Y39 CNAEPVR, 18gps and to no surprise did nothing. The Pioneer receiver is still down converting the 4k to 1080.
So next step, I pulled the SSD, installed a spare SSD and reinstalled Windows. Same issue.
I took my Core i7 PC, pulled the drive and put a blank drive in and installed Windows with the GTX 1050 Ti. Same problem. I removed the GTX 1050 and ran off the M/B HDMI (Intel) and the Pioneer passes the 4k video.
In every case going through the Pioneer the PC with the GTX 1050 thinks it is using the DVI port.
So it's a handshake problem between Nvidia and Pioneer. At this point I see no options besides leaving the PC directly connected to the LG and using the ARC for audio. I don't seem to get all the Atmos stuff with ARC. Not sure what else won't work correctly.
And yes the LG and Pioneer have the latest firmware updates.
This should work too: run an HDMI cable between the video card's HDMI port and the tv, run a DVI-to-HDMI cable between the video card and receiver, select the receiver as the sound device in win 10, extend the desktop to the receiver. I was doing this until I got a new Anthem receiver.
