Yeah. Something is wonky. Tried different cables? Anything else you can get a straight SDI out to test the signal path? Tried different resolutions?

 We do this where we give a straight HDMI out and one particular live stream crew uses I believe a Black Magic HDMI to SDI converter to get into their switcher. Never had an issue and we see all brands of laptops.

Yes, I've tried all types of different cables. Thanks for your input.

Yeah. It only raises it's nasty head when your trying to live stream or lecture/capture. They work fine just connected to the AV systems to do PowerPoint, Youtube and stuff on a HDCP compliant TV or projector. All the systems we have on campus are HDCP compliant. While I have worked with it I don't do video production at work so SDI is not in our systems

Odd, I can do Mac HDMI>SDI>whatever all day long with no problem.

Decimator MD-HX. 
Although it sounds like a different issue.

Maybe I missed it, but what device are you attempting to feed with this signal? Is it a display, DA, switcher?

Specific make & model would be helpful.

I am trying to convert HDMI from a laptop (1280 X 720) to HD-SDI. I have tried both an AJA HA5 and a Blackmagic Design HDMI to SDI Mini Converter to no avail. I am considering getting a Kramer FC-113. Any suggestions?

Get a decimator md-hx and run your signal through the DUC onboard.

I ended up using a cheap HDCP stripper and then all was well.

HDCP every time.
I really hate HDCP problems.  Even if everything you have is "compliant" it STILL may block you.  Getting consumer devices to display on a pro video rig that is using SDI is a real PITA.

I had a gig once where there was a client supplied MAC computer. We set up the speakers for audio, a screen, and a projector. Went to test the video and all we got was the sound. As soon as he went to play the video the screen would go black. Needless to say, they had to find another copy of the movie they wanted in order to play it.

HDCP is the most common video issue if you can't acquire an image.
