Force the Browser Mode and Document Mode of IE 9 to IE 9
Solution 1
IF you have set up the (X-UA..") tags already then that should force it into the appropriate Document Mode and Browser Mode.
It looks like you're setting the document mode in the IE dev tools console, this overrides it whatever you put in as tags.
This diagram explains how IE determines what modes to display in and the dev toolbar takes priority.

Well, Make Sure The tag ("X-UA-...") you are putting should be the first tag inside the Header of your document. Secondly, verify that the html renders (by view source property) in browser, also contains as the first tag ("X-UA-...") in header section.

I need to force both the browser mode and document mode of my IE 9 to IE 9. Now, I've set "X-UA-Compatible" to "IE=9" in the tag of my header, but it has no effect when I change the document mode to either IE 7 / IE 8.
My site is to be compatible only with IE 9 and not with any other versions of IE. Furthermore, I looked through and studied most questions answered here and through blogs (msdn) but nothing seems to be working for me (Before the moderators close this as a duplicate question). Can any one of you guide me about the same ?

<head>tag:<meta http-equiv="x-ua-compatible" content="IE=edge" />
