Thanks for the reply cairo.ferreira.
I want to show web content on 4 of them as if it were a mosaic
I hope this translation is correct. Do you mean like a video wall? So it would set up like this picture, but the media will appear across them all as one large visual?
If yes, you can do that with Xibo for Windows. This guide talks you through how to set that up step by step.
It is very important that you read the requirements section because you are planning to use more than 2 screens. Your PC must have a GPU that supports mosaic mode (nVidia cards) or equivalent software. You must also make sure that card supports the resolution you will have when those screens are combined and enough outputs that you can connect all of the screens to that GPU.
You can also set up other players to show the different content on your other screens.
I assume you plan to use multiple PCs for the content for your 14 screens? You would have to have an incredibly powerful machine to run 14 separate Xibo players, with 4 of them as a video wall.
It sounds like a very interesting project. I wish you well with it and hope the documents I’ve provided help you to get started.
Many Thanks.
