I have had Roku for over 10 years without problems. Currently using a Roku 3 and a month or two ago, the main basic channel display is too large for the TV screen. I have spent a lot of time trying the "display type" option, a power reset, a factory settings reset and nothing works. There are posts regarding this occurring with the You Tube Channel, but this involves the Main "Home" Channel display. The actual apps or channel programming displays ok, it is just the menu. Any other suggestions. Roku support appears to be on an extended lunch break!
