Can i have 4 screens, 3 horizontal and 1 vertical?

Hello!

I will use xibo with 4 Screens. I would like to know if 3 of the could be horizontal and 1 of them could be vertical. And where do I set that?

Thanks and Regards.

If they form a rectangle and if your PC can drive them as a single extended desktop, then yes. You would define your resolution in Xibo and then create your layouts using it.

You would also create a display profile (in 1.7) to set the location of the player to your width / height of your extended desktop.
