Created attachment 113778 [details] [review] [review] set quantization_range in AVI infoframe if the monitor supports selectable range
Thanks, testing = doesn't make any difference for me, but looking I am not sure if my TV supports/advertises it, edid-decode doesn't show it, I'll try more tomorrow.
I added a couple of DRM_ERROR... lines to see if I passed if(drm_rgb_quant_range_selectable and I don't.
But even if I did I don't think that patch will work as I only get one message at the start - I would have expected that flipping between tvrgb and bypass (which works OK) would have generated more, but it doesn't.
Added complication - I am testing on your drm-next-4.1-wip (yesterdays so patch applied by hand), which has issues for me as reported elsewhere (as expected due to these I don't even get the debug line until I take a second strike at xrandr)
