I just recently purchased 4 Hisense - 55" Class R6G Series LED 4K UHD Smart Roku TVs to create a 2x2 video wall. The top 2 TVs are mounted upside down and I need to flip the display on those TV's so that the image is right side up. I cannot find a way to natively flip the screen upside down via the Roku settings menu or secret menu. Is it possible? If not, is there an app or streaming device that I can use to flip the screen upside down. I made a terrible assumption that all Smart TVs had the ability to HV flip and clearly that is not that case. Feel like a complete idiot. Any assistance/advice would be greatly appreciated. Thanks!
