Solved my Mac HDMI problem

This Mini Converter solved a problem we've had for some time with extensive configuration needed to get our Macbook Pros to display 1080p on our ATEM Switcher. With the BMD mini converter all three Macbooks were plug and play once we got the switches set right. Found it very helpful to read the manual on configuring the switches.

This is must have for Virtual Production.

For cameras that don't have Genlock (not to be confused with timecode) you'll need this low cost device for filming with a LED wall.

Blackmagic releases firmware updates for their converters, like the Blackmagic Design Mini Converter UpDownCross HD, and users should not experience jitter on the HDMI output.

For a live shot using a Sony FX6 and a TVU unit, can I use this to split video and audio from the camera to the TVU and to an external monitor without problems?
Asked by: ed
Yes.I’m using 5 of them now in live tv broadcast without any problems or delay. Figuring out the dip switch positions for the desired result resolution is a little tricky but once you figure that out, works great. Suggestion, figure out the dip switch positions before installing them in a tight location.
