another question,
can you force chroma subsampling switching within dsplayer and its renderers or filters?

if so how is it done?

MY DESKTOP AND SOUND SETTINGS (SAPPHIRE PULSE AMD RX 560 4GB)

Desktop Pixel Format and Colour Bit Depth:

Desktop Display Settings (3840 x 2160p 60HZ):

Sound Settings:





madVR Settings:

Kodi DSPLAYER Settings:

JVC info Panel:

When Playing 1080p upscalled to 4K:





When playing 4K HDR Movies:

I am not 100% sure if the JVC info displayed is correct or if it should be different like (YUV) instead of RGB.. would appreciate some help here.. Thank you

you are correct but fail to recognise that the settings are only for when you are using Kodi's built in videoplayer and Kodi's GUI.

if using dsplayer then LAV audio takes over for bitstreaming. as such the use of wasapi for HD audio is null and void.

some AVR's dont have "send low signal noise" function to keep such things as "auto standby" off on other connected equipment for which a subwoofer is one of them. so we need to keep the audio device alive that we are using in kodi to sent a low signal to the subwoofer or indeed active speakers etc.etc to stop them going into standby. if you dont want to keep your subwoofer/active speakers alive or your AVR has the same function then turn the setting off in kodi.

 NO, I do fully understand that.   But regardless, that setting STILL applies, that send low signal noise.  It's ACTIVE when y ou are not watching a video.  it's always sending a low signal noise, and the AVR may not catch the change from the video sound to instantly the KODI send low signal noise.  

I'm saying, try turn that off, and see what happens.  See if your AVR turns off the audio format last sent.

Just two things. The desktop is set to 8-bits RGB at 60hz. But what about at 23hz? You are outputting from madVR at 10-bits, so you want the GPU to be set to 10-bits RGB at 23hz. Play a video and return to the GPU control panel while it is playing. Set it to 10-bits RGB. It doesn’t matter what madVR reports.

Second, you have disabled calibration controls, which means madVR defaults to BT.709. Your projector is calibrated to BT.2020, so it must convert from BT.709. You can do this in madVR by selecting this display is already calibrated and setting it to BT.2020. The gamma doesn’t matter as it’s ignored, but try and guess the gamma, too.

Some debanding at low/medium wouldn’t hurt. This won’t remove any image detail and can help with the odd Blu-ray, even if it is uncompressed.
