Question about multiple monitors
I’m working on a project that will be a grid of 3×3 monitors. In other words, 9 monitors. Each monitor needs to be able to show independent content, but usually nothing fancy, just changing background color or displaying a jpeg. Ideally I’d like to be able to play a movie across all 9 monitors from time to time.
Is this the sort of thing Jitter can handle?
If so, would I make one big canvas and break it into parts, or 9 different canvases?
Thanks for any help.
hmmm, someone can correct me if i’m wrong, but sounds like a job for two networked computers.
i can see possibly 8 monitors from one computer. two cards, two outputs on each card, two triple-head-to go’s. 9 would be pushing it, but maybe it’s possible.
you would create a rendering context per card and i don’t think you can share resources across cards.
really need more information (hardware setup particularly) to be of much help, but yes jitter could handle this.
Yes, this is possible.
We’re using a Mac Pro (dual quad-core) to drive 8 projectors at 1024×768 + 1 control monitor.
There are three graphic cards in the system. The two "powerful" cards are each connected to a TripleHead2Go unit, and the weaker card drives the control monitor, and a TripleHead2Go in dual-head mode.
I am reading a single large movie file, and using jit.scissors to split it. Would have liked to have used OpenGL, but our movie is bigger than the max supported OpenGL texture size, I think.
that’s pretty awesome to hear. what kind of fps do you get? and what are the cards you are using?
and here im working on a project with 7 ouputs/projectors and a workscreen
using a 2008macpro and 4 videocards (ATI Radeon HD 2600 XT)
in opengl using shared_context at 25 fps…
you can share resoources between two outputs on the same gpu
so in my case i use 4 gpu’s and i have the make the textures just 4 times and share it 3 times (4+3=7)
