Avs hd 709 calibration disc3/30/2024 Also, there's no Deep Colour on any Blu-ray discs. So generally it's fairly pointless to output anything more. The Blu-ray standard only supports bt 709 which limits chroma sub-sampling to 4:2:0. These are by far the most important settings on any display, and you don't need a chromameter to set them correctly, you can use a simple greyscale test pattern and your eyes. Set your Blu-ray player to YCbCr and then use a calibration disc such as Spears and Munsil (2nd Edition or AVS HD 709 ) to set Brightness (black level) and Contrast (dynamic range). Generally, better dynamic range is preferable, so it's usual to be able to distinguish levels of white between 235 and 255 without clipping, but technically speaking the brightest white should peak at 235 if the source material truly conforms to standards.Īssume the primary use of the display is to watch HDTV (bt 709 is the world standard - it's often still referred to as rec 709). Values below 16 are usually still in the signal, but you shouldn't be able to distinguish different shades of grey below 16 - they should all look totally black when your display is calibrated in a dark room. The video world, unlike the computer world use a video level of 16 for the blackest black and 235 for white.
