Well, now we want to output VGA video with ADV7391 chip, and we want to output VESA video with 1280x1024@60hz. I configured IIC according to 1080P 30HZ, the input data is YCBCR, the output is RGB, and the timing is output according to 1280x1024@60hz. Now the image can also be displayed. However, there will be several problems :
1. The image is not centered (I control VGA hs and VS according to VESA standard, but it is still not centered).
2, the color gamut is not normal.
