Problem with HDMI - SDI Adapter (Black Magic Design)

Hey guys.


I recently bought a MacBook Air M1 and was just trying to connect it to a projector via HDMI (actual signal chain: MacBook Air M1 --> Anker 8-in-1 USB-C Hub HDMI Port --> Black Magic Design Mini Converter HDMI to SDI --> Black Magic Design Mini Converter SDI to HDMI --> EIKI LC-XT5 Projector).

The MacBook recognized the projector with no problem, the screen on the MacBook is stable, but the projector puts out a flickering image, with seconds of black screen, tearing etc., basically unusable.

I have used several different Windows Laptops with this signal chain and had no problem whatsoever.


I had this problem with Macs in the past, but never owned one. Now I want to know what the **** is going on.


Is it a problem with HDCP Versions?

Could an HDCP Converter like https://www.amazon.de/LINDY-BIDIREKTIONALER-HDMI-KONVERTER-38166/dp/B078ZCVGMY/ref=sr_1_1?__mk_de_DE=ÅMÅŽÕÑ&dchild=1&keywords=lindy+bidirektional+hdcp+konverter&qid=1614619116&sr=8-1 solve this problem?

Does this problem exist with original Apple Adapters or Adapters recommended by Apple as well?

Or maybe it's just a M1 issue and will be solved with future updates.


As I said above, it is widely "known" that there are problems with MacBooks outputting video over a long distance. So far I don't know why and how to solve this issue.


Thank you guys beforehand!

MacBook Air 13″, macOS 11.2

Hello lukasnader,


From reading your post, it sounds like you are trying to find a way to use a projector with your MacBook Air. This is a great way to let everyone see what you are doing and want to offer some help.


The best thing to do is to try to see exactly where the issue is occurring. Since there are multiple converters, start by removing everything possible in the chain. If it works, add the various components back until you find the problem.


Also see if any of the steps in this Apple resource help: Get help with video issues on external displays connected to your Mac


We hope this helps.


Have a wonderful day!
