I recently upgraded my old Verizon Fios cable boxes and Remote to the new 4K Verizon TV One Boxes and Remote. I have only had this new Fios cable equipment for 2 weeks and I am still learning features on the Remote. On my old Verizon P265 Remote, there was a button at the bottom that says size. Many movies on HBO and other premium cable channels are in letter box. On my old Verizon P265 Remote, I could make the size from letterbox to Full screen. It doesn't look like the Verizon TV One Remote doesn't have this feature. If there is a way to make a letter box movie on HBO to full screen, please tell me how to use this function on my new Verizon TV One Remote.
