Summary0001867: [Smart3][ATV12] Request Amlogic to analyze AVR EDID data
DescriptionHi YK,

When we do the Netflix verification, we find a phenomenon:
The resolution abnormally changed when connect HDMI cable to a AVR, eventhough DUT just stop at the home page and don't play a video.
(I think it's not related to Netflix)

Steps:
1. DUT connects a 4K sony TV, and AVR power on.
2. DUT stop at home page.
3. plug out DUT hdmi cable and plug in AVR hdmi cable.
4. wait 20 seconds and make TV hdmi cable plug in AVR.

I find that the EDID raw data are different between the normal and abnormal case.
The "Display Capability" are different:
normal: 3840x2160
abnormal: 1920x1080i
The EDID raw data is displayed below.

Please report to AML KOR for help to analyze it.
Thanks~




FW version: ro.vendor.vasott.version=k000c-537nts-03_SD-20231228

normal case:
When do all steps, TV will show the resolution (4K).
