Hi,

accidentally changed display mode to 720x576@50hz my tv now says unsupported display via HDMI..
now i'm connected via airmirror to correct the display mode but its now blank.
pulled up this command
> cat /sys/class/display/mode
> 576cvbs

how can i get the old display mode of 1080p60hz so that my hdmi display will work.
Thanks.

nevermind, I connected it to 2 televisions and gave me unsupported resolution display.
then I connected it to my older LCD panasonic viera tv. it defaulted back to 720p60hz and i got HDMI display back on all tvs.

Nothing like a little self-inflicted pain to keep us on our toes.
Glad you got it back.
Cheers.
