Hi KenHoustonTX,

Welcome to the Roku Community!

Thanks for getting in touch about this issue. Have you tried using another HDMI port on your TV to see if there are any differences? We also suggest trying the device on a different TV to see if you're still seeing the same issue.

Let us know if this works for you. Thanks!

Regards,

Rey

I tried different HDMI Ports, different cables.  Rebooted the TV.  Upgraded SW to the TV (it hadn't been upgraded for years).  Another HDMI device at 1080 works fine on the TV.  I could get the roku  working with a computer monitor at 1080.  Either 1) the TV somehow stopped supporting certain 1080 devices (again there was no change to the TV), or 2) possible SW update on Roku devices (possibly with encryption?) caused the failure.
