A:Answer Hi there. Thank you for sharing your experience with us. We understand your inquiry about adjusting the screen ratio for streaming apps like Peacock or Prime Video on your OLED48B5PUA TV.
Your OLED48B5PUA TV does provide a range of picture sizing options through the TV's menu settings to change the aspect ratio. While some streaming apps may lock the picture size based on the original content format (such as cinema aspect ratios that result in black bars), your TV offers various modes like Original, Just Scan, 4-Way Zoom, and Vertical Zoom that allow us to adjust how the picture fills the screen, including a "fit to screen" option, when the content permits. We recommend using the Magic Remote to access the Picture Settings while streaming to see the available options for that specific content.
