I have my TV professionally calibrated and don't want to touch anything... I have a couple of questions. \r\n\r\nIf I leave SPMC brightness=50 and contrast=50 then:\r\na) does SPMC clip everything below 16 and above 235? and\r\nb) does SPMC pass video levels from 17 to 235 unprocessed?\r\n\r\nThank you in advance."}}
