Part Number: TDA2SX
Dear TI,
My code base is VisionSDK_v3.06 and use TDA2x custom board.
The output dataflow:
I modify some settings in vision_sdk\apps\src\hlos\common\\chains_common.c "ChainsCommon_DualDisplay_StartDisplayCtrl() "

I used a device in the remote side to deserilize the video data and show images in the screen. But it's now looks like below. The curve can be seen while the color looks messy.
Please help me with how to debug this problem. Anything else needed, let me know!
