Dear Sir/Madam,
Please help check below issue.
Sil9134 HDMI out
Implementation: ADV7181D receives CVBS PAL (BGHID) signal, setting ADV7181D 8bit YCbCr output, setting the sil9134 as 576i and 8bit YCbCr input, setting the sil9134 as RGB output, but the screen appears offset and screen images appear blue vertical stripes on the left.
I am sure the video source is OK, because when I input video source to other monitors display, it work well. The configuration of the Sil9134 should be OK, because the configuration of sil9134 on the other boards has been validated.


ADV7181D register configuration is based on an official website to download "ADV7181D_ADV7181D@_ADV7341-VER.1.0c.txt" and "ADV7181D_Manual_Rev0.pdf" , and what I configured is shown below
