My Onkyo includes ISF capable video adjusts. It allows me to change the picture on my screen to suit my preferences. I set it initially and let it do its thing in Auto for the most part. All of my video is upscaled to 1080i and a lot of times I can't tell a difference when the native source is providing 1080i or the Onkyp is upscaling. Many TVs allow the same adjustments but they are normally done by a tech. The Onkyo just gives my old Samsung the capability when I need it.
