I'd be interested to know why the Android kernel is polling instead of using interrupts?for hpd detection, possibly because of?the interface VGA??

For those of you who may be interested, I've confirmed that the hdmi interface does work using an interrupt handler for hpd, furthermore?EDID detection also works via i2c5. What is important is that?VDD10_LCD and?VCC_18 need to be powered for hdmi to work.

Hi all,

Can you please let me know how to connect with support team? I am also facing one HDMI related issue in Android-9 in below scenario.

- If I trun OFF the TV and wait for some time and then turn ON the TV
- In this scenario failed to get edid error error is coming and TV is running in 720p resolution by default.

And also restarting the RK3399 board is fixing this problem.

Can any one of you please help me with this issue. And let me know if any further information required.
