When using TVP7002 with the VGA as the video source, on the bottom of the image there is colour bar or green bar seen in the below image.
Trying to adjust BT1120 clock phase didn' t make any change. When access to VGA, read TVP7002's register info, it showed the total line number, valid number of lines in the image and the line number of blanking region are all correct. For example, under 1280*1024 resolution, the total line number is 1066, blanking region is 42, valid line number is 1024.
I just wonder why this green bar happened, and is there any recommendation to improve this?
Thanks a lot for your help!
