HDMI to RCA converter to connect FS Attitude tp Ph4

[zippomaker]

Hello everyone, I have installed the HDMI transmitter module to connect to Ph4 the Fatshark Attitude, I'm trying to understand what HDMI -> RCA converter is best for my purpose. . I saw this converter: HDMI to AV Video Converter Surports HD 1080P RCA Output or this cable but I do not know if appropriate: High Quality Gold-plated Connector HDMI to 3 RCA Converter Cable 5 Feet -Black
Has anyone had similar experiences? Thanks

I have basic FatShark goggles and tried to use similar converter with USB power, I dont like image quality, so considering to get HeadPlay googles so I can use real HD with HDMI.

Is it necessary the USB 5v power?
