Hi Kerwin

I checked the same LG TV here and found that OS12 and OS10 have different information.
Please check it

Thank you

Hi YK,

the information <preferred_Video> of hdmi-edid.xml is from /sys/class/amhdmitx/amhdmitx0/preferred_mode.
This information is from Amlogic hdmitx driver.

We hard-coded the customer LG TV's edid in hdmitx driver, we can get the same results as you.
ATV12 has information in /sys/class/amhdmitx/amhdmitx0/preferred_mode.
ATV10 has no information in /sys/class/amhdmitx/amhdmitx0/preferred_mode.

One thing we feel weird is as belows,
when we cat /sys/class/amhdmitx/amhdmitx0/disp_cap
576i50hz
480p60hz
576p50hz
720p60hz
1080i60hz
1080p60hz
1080p120hz

1080i50hz
1080p30hz
1080p50hz
1080p25hz
1080p24hz
2160p30hz
2160p25hz
2160p24hz
smpte24hz
smpte25hz
smpte30hz
smpte50hz
smpte60hz
2160p50hz
2160p60hz* <---- We can see the * sign
640x480p60hz
800x600p60hz
1024x768p60hz
1280x1024p60hz

But currently, I don't know why /sys/class/amhdmitx/amhdmitx0/preferred_mode is null

I think its' common issue. (Intek and Innopia also have the same issue).
Could you check it with Amlogic?

Thanks,
Jason
