HI Jean_Magallones, welcome to the community!
How to proceed will depend on whether you want to create:
-
A multi player installation, which uses four Xibo players running from the same machine, each with its own screen.
-
A video wall, which is one player but the media is spread across all connected screens.
If you decide to create a video wall, please make sure to read the requirements section of the guide carefully, as you are planning to use more than two screens.
In both cases you will need to have a PC that has all of the video outputs you need to connect to each display.
If you plan to use four screens then your PC/graphics card will need four video outputs. HDMI is the most common video output port that is used for this type of setup, but you will need to check you hardware to see what you have.
I hope you find the documentation links help you to set up the display type you plan to use.
Many Thanks.
