On site struggles with a previously working planar wall via Mac mini > Datapath FX4
Long story short, did a Planar LED wall years back , Mac mini m1 with Switchres X running a custom 1920x1350 resolution. Mac goes thunderbolt > hdmi into hdmi 3 of a Datapath Fx4 HDR, then that cuts the image into two halves @ 960x1350 each and sends two outputs (1&2) into two Planar S6F led senders respectively.
Worked flawlessly… until their IT department went and updated the machine to Tahoe OS and now I can’t get the output to display properly , it’s just a black screen.
Verified the signal from the planar LED senders (S6F) is good, if I plug the Mac straight into each sender I get a clean image on the wall. I cannot however get an image properly from the Datapath outputs.
According to the status page of the Datapath in wall designer the ins and outs look fine and are showing the correct signals but I’ll be damned if I cannot get an output to show up on the wall.
No clue what’s changed in this update or if that’s even what’s causing the issue… any advice or suggestions greatly appreciated .
