Windows 8 Pixel density large screen

I have Windows 8 Media Center Edition running on an HTPC and would like to make the Metro icons 'larger' on my 62" 1080i TV. I've found a blog article that discusses how Windows determines pixel density based on resolution, however I do not see a way to change the default assigned values for my resolution via the UI. I know this can be done as I saw a 2012 Build video where they demo'd a large screen touch display and mentioned that you can over-ride the pixel density via the registry, I just don't know what key. Help anyone?

Solution 1:

Check this article:
