You need a way to attach the monitor to the PC. The BBB has ONE built in interface for a monitor - the LCD pins. These pins can be connected to either the HDMI port OR they can be connected to an LCD monitor.
Like any other computer, in order to get more monitors than that you will need to install another interface. So you could use a DisplayLink based USB monitor to get a second monitor if you wanted. Unlike a windows computer, Linux has lots of weird little experimental video drivers made to scratch an itch. There are at least 3 different SPI display drivers for linux, one of them might work. See https://github.com/notro/fbtft for a working driver using SPI on the Raspberry Pi. There are at least 2 different GPIO drivers that bit bang the lcd controller. One of them is again, https://github.com/notro/fbtft There are also a number of "virtual" display drivers that create a virtual screen[but then you need some way of switching to that frame]. For example, if you setup VNC Server on your BBB it can be configured to provide a "virtual" monitor display for remote users. There is probably a way to configure it so you can have multiple monitors over a single remote system as I'm sure someone would have played with that - it just might not be very reliable. There are also TWO projects primarily focused on providing "auxilary LCD display" capabilities: LCDProc http://lcdproc.omnipotent.net/ LCD4Linux http://ssl.bulix.org/projects/lcd4linux/ Their primary focus is in using text LCD displays such as those sold by CrystalFontz http://www.crystalfontz.com/ but I have run across hacks/drivers that build off of those projects to use some of the more advanced LCD's as regular displays. It all depends on how much "work" you want to put into it. It you want to just do "plug and play" go with a USB Display. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
