HDR switching is now working with the latest driver but wasnt for a few versions, i'm currently using 18.8.1, seems very stable. There does seem to be an issue with colour space though which i've logged to AMD. For some reason 23,976 SDR playback can massively overblow colours in some setups, not all, it does it with mine. There is an easy fix though, just callibrate for a BT2020 display in MADVR. This doesnt affect HDR playback or playback at 60hz and may not happen if you put your TV in PC mode, I use BLURAY mode to get access to motion interpolation which isnt available on PC mode on my TV for some reason (2015 LG OLED). otherwise 23,976 playback is solid, frames skips / repeats are measured in days on my system, even for 3D MVC playback. You should be able to get NGU high running on the 480 for both upscaling and chroma as its very similar to my RX 580 card. |

@Siso supersampling will always double and then downscale, even if the source definition is equal or higher than the display definition

"...only if any upscaling is needed" will always double as soon as the source definition is smaller than the display, e.g. if you have a 1920x1080 source and a 2560x1440 display it will still use doubling.

Where "...only if any upscaling is needed" gets problematic is cropped video that almost matches the display resolution, like slightly cropped 1080p on a 1080p display. You usually do not want to double 1440x1046 before downscaling it for a 1920x1080 display.

the opposite a scaling factor of 1.2 or 1.5 to avoid doubling for a couple of pixels.
you don't have to think to much about this there are not a lot of files out there that are between 1080-1440p so this doesn't really effect you |

ok, thx HilliSan & MCLingo, I will give it a try today...
Edit: Changed my cards and it does not work as intended. Adrenalin 18.8.2 does not allow me to change to RGB and olny shows YCBCR (when I am on 4K & 60hz), only when I manually change to 24 Hz I can change to RGB Full. And HDR mode of my tv is not triggered. Madvr shows amd hdr, but my tv won't change to hdr mode, the colors are also washed out when madvr shows amd hdr. already reinstalled adrenalin driver several times, nothing changed... Now I will tr to update my system to win1804, maybe this brings the solution.

Also Check your TV HDMI port is defo set to deep colour on, if you are using a different port you might not have changed it. lastly make sure you full HDMI cable path is 18gbps HDMI 2.0 DONT UPDATE WINDOWS 10, you are just introducing another complication here which will make this more difficult to solve Last edited by mclingo; 31st August 2018 at 17:57. |

@Huhn: I am on 8 Bit. Can't change it to any other bitdepth. Cables are ok and worked with my gtx1070 in 4k, 60Hz, RGB Full. I will try to Clean my system from old drivers and reinstall it again. Will report back.

ok, I reinstalled my system and now 60hz, Full RGB is working.
But HDR mode isn't triggering my tv to switch into HDR Mode. Passtrough and HDR Metadata send is aktivated. If I let madvr automaticly choose the hdr mode, it converts hdr to sdr and don't uses the tv's hdr mode too. is anyone here using a amd card with a LG OLED? is this confirmed to work together? My gtx switches into hdr and triggers my tv corretly...
