Awesome video, not sure why this doesn't have more views... I missed only one part. I understand how the software profiles the display and the graphs were easy to understand. I just didn't understand what was changed that achieved accurate colors. I know in PC monitors we can apply ICC profiles in Windows, but I'm not sure what would be the equivalent modification in projectors. Thanks for the videos, very informative!

msesteki Hi and thanks for commenting. OK so unlike ICC profiles we have to manually adjust both the greyscale co ordinates and the colour or CMS co ordinates. I’m a projector normally the cms controls provide us with a Hue Saturation and Brightness or Hue Chrominance and Luminance adjustment for each primary and secondary. The values that we are adjusting here are the Primary and Secondary 100% values but that isn’t always perfect so we need to check and correct these with a sweep from 0 to 100% normally in 20% jumps to ensure the colour engine has correctly spanned then full range. Some further adjustments to correct these then sorts things out. The better way is the growing use of LUT tables which are becoming common on TV’s and we are likely to see more on projectors soon. Hope that answered your question. :-)

Amazing video. What spectrometer do you use? Does xrite pro1 works with calman and works as good?

Man, I'd love to have Andrew calibrate my Sony VPL-HW40ES projector, but unfortunately I live in the US, so that's not possible. And in Michigan, where I live, there aren't any real professional calibrators anywhere near me, so all I can do is make picture adjustments myself using my eyes and a calibration disc. : (

I can't afford this. Is there a decent way to calibrate my tv without any equipment?

You cannot do a complete calibration without equipment .. so no. With some test patterns you can get some of the way and certainly improve your image

Could you tell what projector it was ?

I am so sorry it was filmed quite a while ago and I was focussed on explaining the process. I think it was a sony but gee I am not sure now :-/

@@HomeTheatreEngineering Thanks for the fast response, I was just interested if it was a 4K or only 1080p but I think you said in the video it´s 1080p?! made me curious
