Video Outputs - Update

With the research I've been undertaking, it's become clear that there are at least two main options available if you want to use multiple video outputs - initially I'm looking at about 6 outputs; two data projectors, two standard monitors and two touch screen monitors.

The first option is to build a computer with duel graphics cards - there appear to be a couple of options in the way they can be connected using Scalable Link Interface (SLI) or Crossfire, but either way it seems to take a bit of a hit on frame rate. Although I haven't yet got my head fully around this, it makes sense because you're still only using one processor to drive the whole lot.

The other option is to use two computers joined together to provide multiple outputs.  Again, I haven't fully researched this, but it makes sense because in  this case you have got two processors managing the service - splitting the load.

Multi-screens with multiple computers  - this one might be a bit OTT!

I did contact Jetline systems (http://jetlinesystems.com/contact.php) and after a couple of attempts received a very comprehensive email giving some excellent, helpful and friendly advice.  Jetline are one of only a few companies that build specialised PCs for flight sim - based in the US they only supply to the US and Canada, but have been very willing to provide advice (I've deliberately not mentioned names for the sake of privacy).

Also, in recent editions of PC Pilot, they have started a discussion on home built flight sims - this is a bit limited at the moment as it is focussing on specific builds using purchased components, but I'm hoping they will continue this topic and become more generalised.

Still so much to do and find out, but I'm grateful for the support of the Flight sim community that is out there, always willing to offer help and support to those embarking on this great adventure.
