can you hear the penny drop.... lol

if i'm also correct then madvr osd is only reporting what madvr is doing and not what the gpu is outputting via its settings, which is invisible to the user unless the display device has its own "rendering osd".

this might want an explanation in your guide?  

 This explanation is provided after bit depths. I not sure if I need to say anything more. The guide already has some confusing, poorly-written language already. I rewrote two sections recently but others could be improved.

Configuring a GPU for 4K UHD and Windows 10: If possible, keep your Windows desktop in RGB Full. madVR works in RGB Full. To do this, I recommend the following:

• Set the desktop to 3840 x 2160 with RGB Full at 8 bpc at 60Hz;
  
• Ensure frame rate matching is activated in the video player or madVR;
  
• Play a video with a different frame rate (e.g. 23.976Hz);
  
• Return to the GPU control panel while the video is playing and change the bit depth to 10-bit/12-bit to match the output bit depth in madVR.
  

Now your desktop will remain at 8-bits while video playback will be matched to 10-bits. Do this bit depth matching for each frame rate. This will keep everything at RGB Full and eliminate unnecessary range conversions from madVR to the GPU, which is always the preferred outcome. If you are using RGB Limited instead, adjust accordingly.
