Mirroring the Remote Control screen on the EV800D via Video Cable

Hello! I have a FIMI A3 Drone and the FPV EV800D. I already use the glasses with the FPV drone, but I want to connect the EV800D to the drone's Remote Control via CABLE, to see the technical flight indicators that are displayed only on the remote control screen. I've used several types of cables, but none of them worked correctly. The most I got was this visualization by cutting the upper part of the control screen, as per the PHOTO ATTACHED. What is the correct cable to buy and where can I buy it? Grateful, Cleidson Prazeres
