It is unfortunate that there are sometimes inconsitencies in how different software packages, drivers and hardware deal with video levels. The color space issue was addressed to some degree in this guide. I am guessing you will address some of these issues in part II? This is all measured on a meter on a set calibrated to 16-235 from another source (stand alone bluray player) In order to get correct black levels when using TMT I need to set the output to 16-235 to get 16-235 output (even though in MPC etc I need to have output set to 0-255 to achieve the sameā¦.) To make matters more complicated things can be different for HD (Rec 709) and SD (Rec 601) material as well as proteted path material. Setting the output to 0-255 means I actually get 16-235 out for a 16-235 source. At various points the video is converted from/to 16-235 / 0-255 and what actualy happens when playing back video with the output set to 16-235 results in the renderer assuming the input is 0-255 and converting this to 16-235 (giving you washed out blacks and grey whites). I have a 9400 IGP and if output is set to 16-235 for video and I play a 16-235 video then you would think that output would just be at 16-235 it does not work. The choice of codec and renderer can affect what is displayed. The major issue with HTPC display calibration is that things are not static.
