Exporting 4K from FCP to play on Hyperdeck 12G

Hi There,

I need to create some 4K files from Final Cut Pro to then play on a Hyperdeck 12G. I can do this with HD footage and it works fine but has anyone found the settings to export from FCP to create a 4k file that will play on the Hyperdeck 12G?

Thanks
Jules

If HD works then why UHD doesn't?
Same ProRes UHD export doesn't? It should.

Have you tryed to record a small piece on 12G and then import that to your timeline?
Set FCP to match project settings to content and save settings. Then export video with those settings to the SSD
