I'm using custom made imx6q board(with adv7393 CVBS output only)
I'm already patch BT656 output(https://community.freescale.com/docs/DOC-94019)
so, CVBS output(NTSC) work fine.
some monitor work fine. but, some monitor can't display
not work case, adv7393 SD timing mode set to master mode(self generating timing) and then it could display the screen(timing is not match)
(how to master mode change : adv7393 register 0x8A set to 0x9-default value is 0x8)
i think h/v timing value issue.
help me please...
thank you.
P.S. My source version L3.0.35_1.1.0
Hi Shin ,
Questions on ADV7393, please contact ADI company !
In addition, The MAX clock of CSI on i.MX6 can't be more than 240MHz, check it , please !

ADV7393 is TV encoder(CVBS out)
ADV7393's color bar pattern(self generated) display is nomal for all monitors
but iMX6's BT656 signal though ADV7393 is not display on some monitors(not all)
Most likely, some (non-working in your case) monitors just do not support the resolution of a frame the i.MX6 outputs through CVBS. Please check.
Have a great day,
Artur
