I'm using a Roku Ultra 4800X. Since updating to version 10.5, when turning on my TV, I get an error indicating that there is no cable connected. This is incorrect as the cable is connected to HDMI2/DVI. I click the home button on the remote a couple of times, and that fixes the error, but only temporarily & then I go through the process again to regain connection. This is a really bad update and needs fixes NOW!!!!
