Force IE Browser Mode into Compatibility mode?

I noticed something interesting about my website. It displays correctly when I have the meta tag <meta http-equiv="X-UA-Compatible" content="IE=9"> in IE 8 and 7, but in IE 9 and 10, it does not display correctly. However, they are seen correctly when I go to Developer Tools and set the browser mode to IE 10 or IE 9 Compatible mode.

I was wondering, is there a way you can force IE 10 or IE 9 to automatically view the page in Compatibility mode without changing the mode in Developer Tools? If so, is there a Doctype or meta tag that can do this for me? I've done some research and I've only found Doctypes that allow you to view things in only standard mode, but I haven't found any Doctype that can allow you to view something in Cmpatability mode. Any help would be appreciated! Thanks!

There’s a couple of settings in IE 8 that can cause pages to render in Compatibility Mode, regardless of the page’s HTML content or HTTP headers:

Page > Compatibility View Settings

If “Display intranet sites in Compatibility View” is checked, then IE will render all sites on the local network in compatibility view. (This has happened to me a few times during development.)

If “Include updated website lists from Microsoft” is checked, then IE will download a list of websites from Microsoft and render them all in compatibility view.

If “Display all websites in Compatibility View” is checked, then, well, you can guess what happens.

Tools > Internet Options > Advanced > Browsing

If “Automatically recover from page layout errors with Compatibility View” is checked, then IE will sometimes switch to compatibility view if it thinks a page’s layout is broken.

And, finally, if you navigate to a page and then click on Page > Compatibility View (or click on the compatibility view icon in the address bar), then that page will be rendered in compatibility view.

So, although it’s worth putting X-UA-Compatible in there and using a doctype like the HTML5 one (so that your intentions are clear), always check these settings first when testing.
