No video output matek 743 wing board

Hello fellow fliers! Im coming from a long time with ET Vector and this is my first go at another system. Got the latest firmware on my matek h743 wing board. Got everything setup but im not getting any video output to the vtx. I have the camera 1 set at 9v vsw. I tested both items off the plane and they checkout. I might be missing something on the setup. thanks im a green horn!
