Hello,

 

When I start 3D_Comb function, Output picture has small waving noise issue at when I used CVBS input.

However, this issue doesn't happen when I used Y/C input.

also, when I stopped 3D_Comb, this issue disappear even I used CVBS input.

 

System contens

3D_Comb = On

TBC=Off

64Mb SDR

 

It seems this issue is relating 3D Comb function.

How can I fix this?

 

Regards,

Bogey
