How to change boot up refresh rate to 50Hz

#1

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"

to

setenv hdmimode "1080p50hz"

I think this should be part of the default. There is almost no use for 60Hz for any media box connected to a TV. Do you think you could do the default to 50Hz for CE?

afaik, 60Hz is more common on North America, and 50Hz in Europe… I think its not a big deal, OP could change this value easilly via config.ini in FAT32 partition of SD Card (aka /flash)…

mount -o remount,rw /flash
edit /flash/config.ini via vi, or external editor and add hdmimode='1080p50hz'
mount -o remount,ro /flash

I know (but just for TV broadcasts), thx. But I bet CE is much more common in Europe :slight_smile:

You’re right : https://stats.coreelec.org/ (Click the “Show more stats” button).

I did that. I’m able to mount CE on a Mac OS and change config.ini to 50Hz.

Strange thing is when the Odroid N2 Boots up the CE Logo for a split second pops up with a refresh rate change to 60Hz and then another refresh rate change CE Logo 50Hz with the normal version notification in top left of screen showing and then a momentary loss of connection until refresh rate 50Hz with the skin home screen appearing.

I can see in dispinfo that i have correctly changed to 50Hz.

hmm, maybe its N2 specific, maybe its normal behauviour. Honestly, I am aware that during bootup there are a few disp switches, but never much care about this, as my boxes runing 24/7, and menu is rendered 23.976 (another switch) anyway… So I leave 50/60 defaults due to TV compatibility reasons…

Hopefully devs could comment boot behauviour.

P.S.: Only thing I know about, is that first logo and second logo goes from different locations. The first one is I think tar/gzipped on /flash, the second one is oemsplash.png. Not sure if their switch is accompanied by refresh rate switch also or not.

Same here. I reboot sometimes and i picked the behaviour.
