If the on-screen framing does not look correct, check the codec framing settings for alternative framing modes. Often, the on-screen menu of your codec will look best when the Local Site framing is in Passthrough Mode (:OPMODEBE=1).
If the image on your display looks to be oddly stretched, you may be in Immersive Mode instead of Immersive Everywhere Mode or Video+Content Mode. Immersive Mode will result in your Self View appearing distorted or stretched. Your local/self view will look best when the Local Site framing is in in Video+Content Mode (:OPMODEFE=2).
