Imagine perfect monitor that can display pure blacks and is perfectly calibrated.
What would the contrast be between its second darkest shade of black, that is 1,1,1 values for blue green red sub pixel and brightest white with 256,256,256 values for rgb?
Please note that I mean second darkest shade of black, that means the pixel is active and light shines from it albeit very weakly. I specifically dont want people to mistake this with the darkest shade of black ( rgb 0,0,0 ) which means the pixels are completly turned off and no light exits them.
This is becose with monitors with perfect black, no matter the peak brightness value, the contrast is always infinite. So that is why I ask about second darkest black, not the total black.
I know SDR monitors have 2.2 gamma curve target and have 256 possible values of becose they are 8bit. I know 8 bit has 256-1 contrast ratio assuming the brightness change is the same between all the bit values but since the encoding of the digital 8 bit format is not linear like RAW files, I have no idea what contrast/dynamic range 8bit is supposed to have becose I dont know how much are the individual bit values spaced apart.
If this theoretical perfect SDR 8 bit monitor had peak brightness of 100 cd/m2, how bright would the second darkest shade of black be?
