My old Roku was frequently resetting so I purchased a new Roku Express 4K+ to take advantage of my 4K TV (not Roku). Setup went OK - Roku detected TV as 4K but on the next start the picture was all wrong - like I was looking at a small portion of the screen Zoomed in. I have to go to Settings and reset TV type every time I start it. Any ideas or suggestions how to fix that?
Make sure the Display Type isn't set to "Auto". If you're using the TV's USB port to power the Express and it powers off the Roku when you turn off the TV try using the supplied power adapter. If there's a "power saving" option under Settings->System->Power try disabling it.
Thanks for the suggestions. I am using power adapter so not USB connection. And I tried several different settings - Auto detect as well as 4K explicitly. In most cases after longer power off the video is wrong and I have to change it.
