I had just asked the same question about a week ago. I ended up buying that very "for in the wall installation" cable and today have been trying to get a good setup. The SGVA cable at 35 feet for me displays fine and image quality looks ok, not as good as it did when I had it connected via hdmi but my tv has only 1 hdmi and I didnt want the extra expense of the switcher so I went with vga since it was available on the TV. Everything looks fine and display fine. I have read that in most cases VGA will be easier to setup since overscan issues crop up with DVI-hdmi.
