Dominator V2 upgrade - lower resolution?

I just bought the Fatshark Dominator V2 DVR upgrade kit from ReadymadeRC - they weren't available in Aus at the time, but are now at NextFPV

After installing it, the video is now lower resolution...? Hunting for a config change or something - if anyone knows a fix please lmk
