No fullscreen with two thunderbolt ports.
Hello. I had a problem today to connect two simple monitors (with two thunderbolt adapters). I was on preferences, change stage settings, and Isadora recognize the two monitors but don't show the second stage. In mac Monitor preferences i visualize the separated screens and try make like the matrox dual head system but can't.
have you tried to show the alignment grit at the outputs?
As I know, native screen spanning like with an matrox xhead is only possible with some professional GPUs like the NVidia quadro or AMD FirePro cards.
It shouldn't prevent Isadora to use the outputs, anyway!
A screenshot of you patch and setting would be handy here. Don't forget that you need to change the stage to 2 in the second projector actor.
Please also tell us about the machine you are using. Is it a Mac Pro? Or?
also, if you are using HDMI or DVI you can only use two signals in total with passive adapters. So your control monitor plus one.
If you use active HDMI/DVI adapters, you can have as many outputs as you have thunderbolts. VGA adapters have no limitation.
