Hi Alex and all,I got directed here from another forum by Alex. Thanks Alex, it seems I may have found what I'm looking for.I currently use FS2004 on 3 PCs with WinXpProSP2 and WideView running on 3 x 20" CRT Monitors (they are flipping _huge_ but they were free!)I'm building a B737-800NG cockpit with all the bells and whistles. Home made, and I have zero engineering or woodworking knowledge, so it's a bit rough!I've been playing with the monitor setup and have come across the devilish problem of synchronising traffic across the three monitors. No matter how careful I am with trying to get the traffic levels and de3finitions the same - and trying to synchronise the FS time across all 3 machines, the traffic runs at very slightly different times on the three screens, causing some fairly silly effects!Also, if I want to fly online, I need to connect all three PCs (two of them as 'observers') to the SquawkBox session - and I get some fairly radical zooming around of traffic on the two slave machines.The ideal would be to have _one_ PC running all 3 screens, but I don't know if my old PCs are up to it.They are Pentium 4 2.4Ghz, which is probably fast enough, but the drawback is they only have one AGP slot each, and no PCIExpress. They also only have 2 slots for RAM, so I am limited to 2Gb in each machine.I have tried a dual head in the AGP slot and a single head in one of the old PCI slots, but I do not seem to be getting hardware acceleration on the PCI card, giving lock-ups and very bad frame rates.I got to wondering about a Matrox TripleHead2Go, but am aware of the drawbacks in terms of view settings and needing to use the VC.I have a Chirstmas Bonus coming up of around

Roger- I use an ancient AMD 1.8 GHz system with an AGP GeForce FX 5200 card and a PCI same type for the third monitor.

Just one question before I start a new thread. When you say 'same type', exactly what do you mean? Same manufacturer, obviously - i.e. both Geforce - but what is the capacity of the card, is it another 5-series?Thanks again for your help.I am also RW pilot - Piper Warriors on a UK NPPL plus 3-axis and weightshift Microlights on the same licence (I got the Micro rating before the SEP).I've used both Track IR and multi-monitors and I have to say I like both for different reasons. Using VFR scenery for navigation exercises, it's nice to be able to 'look over my shoulder' with Track IR an just double-check for the fifteenth time that the railway does indeed cross the canal at right-anlges (just like I do in RW flying - I'm forever checking and cross-checking), but I love multi-monitor for the wide view and wide horizon, plus the peripheral clues it gives even when I'm concentrating on the view ahead.I use both. 3 monitors and a hardware panel/switches etc. when flying the big tin, but TrackIR and VFR scenery when tooling around or practicing RW navigation (I used this system before taking my cross-country navex whwn doing my NPPL over unfamiliar territory - the power of VFR Photographic scenery is not to be underestimated and a navigational procedure trainer...)Anyway, enough. Just let me know what you mean by 'the same' - what is the 'sameness' that's important. Thanks, and Merry Christmas to you too!Roger.

It's my understanding that both cards have to be able to work from the same Driver. Thus same Mfr. & family but not necessarily identical cards.I believe many other varieties of vid cards also work OK- mine just happen to be ancient!I'm not a tech- anyone out there with more info?Alex Reid
