I am sick of seeing the Error 20 black screen stating my HDMI connection does not work and I cannot receive a picture . After reading many blogs, following the suggested solutions over and over, then in frustration trying to return and exchange my device, I have boxed up my 2020 Roku Ultra 4800 and bought an Apple TV device (which when hooked up to the same HDMI cable works perfectly). I thought of buying a new Roku, but when reading the various blogs, determined that I would run into the same or similar issues that Roku will just ignore.
I have tried everything suggested and my Roku still does not work. The device is less than a year old and was working perfectly until the 11/17/21 os update. I do not appreciate Roku’s determination to ignore that they have a software problem and blame the consumer.
I am very unhappy with the Roku system, and will refrain from further purchases or recommending your product. #Roku Ultra 2020(4800 series), @Error20
