=11ptok, so your chain is fully 4k.

There are some issues with MADVR coming going back to 4k from 1080p but as far as I knew it only affected 3D. If you play a 3D movie then stop it you'll get a black screen and either your PC will have crashed or you have just lost HDMI handshake. To check this setup an RDP connection from another PC in the house or your mobile phone,  if you can logon then its just HDMI loss.

Getting back your HDMI.

1. Create a script or batch and program this to your remote, this often wakes mine up again.

2. If this doesnt work turn your AVR off and your display, then run this again, then turn on your AVR, then your display.

Prevention. =11ptFirstly, your PC should never need to go into 1080p mode so why is it?, this suggests to me you’ve not got something setup right in MADVR or KODI DS as everything should be upscaling to 4k, the only time it will go into 1080p mode is when you are playing something in 3D, if this is the case then you have the known bug and the workaround is above, don’t use MADVR refesh rate switching.

Things to check.

1. KODI DS gui MUST be 3840x2160@60hz (same as desktop)
   
2. KODI DS SYSTEM – you MUST use windowed mode in KODI DS.
   
3. DO NOT use windowed mode in MADVR
   
4. You need FSE for 3D, it should not cause you any issues as long as you don’t use MADVR refresh rate switching.
   
5. DIRECT3D11 – this MUST be on but it might cause blown out reds for SDR material, if it doesn’t let me know.
   

EDIT - ive not played anything in 3D for a while, there looks to be some new issues with it but it could just be the fact ive recently moved to D3D11 decoder in LAV and DS, this seems to produce far more HDMI loss than standard DXVA copy back, disappointing as I can get about 20% more processing out of D3D11

could also be an issue with latest drive but for now drop back to DXVA copy back mode, i'm going to test the last stable driver though.  

Thank you.. I do not care for 3D and will not be watching any 3D movies so that's out of the question..

1. KODI DS GUI is 3840x2160 (same as desktop) but I didn't know you could choose the hz within Kodi? I check Adjust refresh rate to playback.
   
2. KODI DS SYSTEM – I never used windowed mode in KODI DS what effect does this have when enabled please? I will definitely try it tomorrow as I am currently at work, working night shift.
   
3. I don't think I am using windowed mode in MadVR but how can I check please, which tab is it under? Thanks.
   
4. Sure Thank you...
   
5. DIRECT3D11 – this MUST be on but it might cause blown out reds for SDR material, if it doesn’t let me know. I use this with Native mode and no issues with playback.
