Arduino and several picture displays

Projects General Guidance
1

Hi,

I'm looking for an solution to have one main computer with which I can "send" different pictures to a couple (>5) of small (2.4 - 4.3) colour displays.

My thought is to be able to chose a picture on the computer and to easily define which display to show the specific picture. I would like it to work without any need to to reconnect a usb etc. (Possible with a USB-switch?) Do you guys know if its possible to achieve this with Arduino? To have several chips connected though a usb-switch, and to have a colour display to each chip?

Also, as I am new to Arduino. What more do I need except for the Arduino chips (thinking about the Mega 2560?) and the displays? Cables, power adapter, more?

Thanks in advance!

Could this be a direction your looking for? - Arduino Forum - narrowcasting?

You need display driver chips and an SD card to hold the images. If you want to communicate through the USB then you need a USB host shield on your master for each USB slave you have. Remember that while USB has Bus as part of it's name it is not actually a bus but a point to point connection protocol.
You would be better off just using a serial connections to the slave devices.
You do know this is going to be a slow business?
