I'll have to take a look at the JavaScript on the channel page and see what I can find. I don't think you can get the user's screen width/height in inches using JS, but I am also not aware of any "pixel ratio" attribute in JS.Unless they're doing something insane, they're using browser directives - so it's going to be based on whether the manufacturer broadcasts a pixels ratio of 2.
