My 1080p TV is set to 50Hz as most of my viewing content is 50Hz and no refresh rate switch is needed. (I use TvHeadend Client)
I find it annoying when the refresh rate changes from 50Hz to 60Hz and back to 50Hz on my TV booting up or rebooting.
Is there a an SSH command to change
setenv hdmimode "1080p60hz"
setenv hdmimode "1080p50hz"
