Help me please.
GPU 0-255 (Rx 470)
TV 16-235 (Samsung LED UE55B7000)
In this situation the patterns that are created for 3dlut (madvr(.3dlut) TV RGB 16-235 input and output encoding i chose in displaycal) with black at 0,0,0 or 16,16,16?
In faq on the first page:
"3) Display wants 16-235. GPU is set to 0-255. madVR is set to 16-235.
This is the recommended setup for best image quality if your display can't do 0-255. This setup results in banding-free madVR image quality. However, levels for desktop and games will be incorrect, because desktop and games will render black at 0,0,0, while the display expects black at 16,16,16. This is a problem for ArgyllCMS, because Argyll will create test patterns with black at 0,0,0, and the display will also receive these at 0,0,0. So basically Argyll test patterns will have wrong levels, which will screw up the whole calibration.
It is my understanding that Graeme implemented the -E switch specifically for (3), because without the -E switch Argyll test patterns would send wrong levels to the display. Basically the -E switch tells Argyll to render test patterns with black at 16,16,16 and white at 235,235,235, which Argyll never had to do before. When using VMR/EVR, you usually switch your GPU to 0-255 or 16-235. In both cases Argyll can render test patterns with black at 0,0,0, and they will still be sent to the display with the correct levels. However, due to my recommendation to use (3) if your display doesn't support 0-255, Argyll suddenly needs to render test patterns differently. Hence Graeme implemented the -E switch."
