You did read the first page - did you ? One of the key elements madVR is doing is scaling and madVR does this far better than any (or most) other solutions on your pc. So if you are scaling before you feed your video into madVR you are doing something wrong (imho), the best case is it to leave your video they way it is and let madVR handle the proper change from 4:2:0 to 4:4:4, the scaling and the colormatrix (601 or 709).
I have been on this thread from the beginning, so yes I read all pages. I am not concerned about the color space from 4:2:2 to 4:4:4 as I am aware of this. If you read my thread correctly I am concerned whether MadVr uses the correct Lut when scaling to the NATIVE resolution of my panel. If it does, GREAT. If not it would be nice to have a selection within the GUI for 601 or 709.

The reason I ask this is: Is MadVR is using the scaling values from powerstrip to identify 601 or 709, or is it using a flag within the stream to identify SD or HD. If using the first situation we will have the wrong lut in use. The use of the PC to scale has been done by many as you are aware, and to give control over custom porch values on a CRT as well.

MadVr has no capabilities to change resolution, it is the job of the graphics card; ie from (SD)720 x 480 to (HD)1920 x 1080p. Please correct me if I am mistaken as to how MadVr determines LUT usage.


Thanks,
