i tried with two kind of TH2G, DE & SE,

I always use and recommend the DP (Display Port) Edition

@administrators woland thanks for your advice.

with the DP edition i manage to have 3 screen, but there are the same, and not one next to another. i'm trying to adjust it with matrox soft, but it doesn't help.

with the digital edition, i manage to have my 3 screen, with the help of SwitchResX, but the only resolution the screens allows me is 2304x433, when i try to add a new resolution in SwitchResX the screen tell me it's unaccepted format.

i think maybe those screen are the problem... JVC TV screen, it was all blacked for the show, i'm looking for the references ....

To be able to set a custom resolution in SwitchResX you have to disable the System Integrity Protection in the terminal. If you search on Google you will find how to do it.

If you are running Mavericks, this is not an officially supported operating system for Isadora. Isadora 2 is designed for MacOS 10.10 (Yosemite) to MacOS 10.13 (High Sierra). That's not to say it won't run on older systems, it's just that we do not support for those older OS's and do not recommend using them with Isadora 2.

Best wishes,

System Integrity Protection was introduced with El Capitan.

thanks anyway for your help !
