Additional Monitor

I have a Minibook from Maplin, it has 3 USB ports. Can I connect to a larger monitor, and if so how?

Hi, errm, i know that most monitors won't work becasue we lack a VGA cable, but if we can get a USB cable then that is great the only thing is the GUI may still be 7 inches or worse, pixelate madly.

Thank for this site, I have looked them up. They also have a lot of different cables. Although not sure about a 15 pin DVI-D, (which I think is what I want) to USB. Another question then is will the Linux software allow it to work?

Think USB monitor support has to be built-in to the kernel (OS) when it's compiled. Not sure how we'd find that out, but I'm guessing if there is a module in .../.../.../modules dir. somewhere then they wouldn't include the module unless the pointer to it was built in to the kernel. If so it should just then detect the monitor when plugged in, but guys... this really is all a bit off the top of my head  ???

It's a system called DisplayLink. www.displaylink.com

The hardware support is in the monitor or a splitter box.

Mac & Win2k and above drivers are on their website but no Linux, although it says in their knowledge base that they are looking at support for other OSs.

You can't connect a Monitor to usb - as already said, there are USB graphic cards by DisplayLink, but there are two issues:
- they recently added Linux support, but so far that's just a library, the Linux driver is work in progress, I'd expect it in Linux 2.6.31 or 32, may not work so well with Linux 2.4.20 in the minibook.. (But maybe we'll get a up to date kernel till then ;) )
- USB 1.1 That's the biggest issue. It's just not fast enough to transfer the Image in real time - and the SoC is probably not fast enough to process the video stream as well. USB GPUs are a rather slow and CPU intense thing on real computers, so there is no real chance to get this working in a sane way.
On the other hand, according to the data sheet, there are plenty of general I/O pins on the SoC - there have been some software VGA implementations on some microcontrollers, so maybe you can..  ::)
