HDMI Output from a C300 Mark II

Hey, I cannot get a signal on my Viltrox DC-7HD monitor from my C300 through the HDMI output. Have tried all ways. I am shooting 25P. The cable and monitor are working fine as that was the first thing I tested. Interestingly when I switch the camera to 59.24Hz it will deliver a picture (but also swtches the rame rate to 29.97P but I cannot shoot on that for delivery. Any solutions?

Re: HDMI Output from a C300 Mark II

I found zero specifications at Viltrox's web site regarding exactly what signals can be processed.  It literally just says HDMI.  But HDMI version what? And what exact signals?


Note that brands such as Atomos, or Blackmagicdesign have detailed specs as to all the possible signals that can be used.  e.g. 1080p23.98, 1080p24, 1080p25, 1080p29.97, etc.


It's thus possible that the Viltrox unit will only work with a limited set to include 29.97 and 59.94 as you've found.
