I have a question of my own. I'm feeding RGB into my display, as my iScan Duo is outputting a PC resolution (768p). Because of this, my display expects computer video levels. Problem is, having the Duo output computer levels causes visible banding viewing Gray Ramp patterns; in addition, it fails to pass WTW and BTB. I can set the Duo to output Video levels, and this alleviates both issues, but the screen washes out, as expected. My display doesn't allow me to change the HDMI Black Level in this mode.
My question is, if I fix it with the display's controls, does this matter? For example, if my display settings were Contrast 72, Brightness 61 (proper black level and 30ftl) before, and are now Contrast 88, Brightness 31 (for proper black level and 30ftl) when having the Duo output video levels, does everything equate? There isn't much difference between them when set at these settings (very minor white balance and color adjustments), and I haven't noticed any obvious visual problems.
Aside from the more extreme Brightness and Contrast adjustments, is there anything I should be aware of that is detrimental to the image by using this workaround?
