I want to have a wall of TFT monitors, maybe as many as 10x10, and display a video on the wall.
That means that each monitor should display a part of the video.
Her's a bad ascii art example with only 2x2:
_______ _______ |top ||top | |left ||right | ======= ======== |bottom||bottom| |left ||right | -------- ------
Now, either I find a magic piece of hardware which can control many, many monitors, or I need a separate controller at each monitor.
Which is what I am thinking of:
- A master, Windows based, PC where I process the video, slicing it up.
- I then send each slice to the appropriate micro-controller, one per monitor.
- When ready to play the viedo, I send a command only a few bytes to each MCU, which ought to guarantee that they are in synch.
What do you think? Is there a problem there? Is there a better way?
