Here I need some thinking with me of you guys.I own a Digital DualHead2Go which was connected to two 26" widescreen monitors --> 3350x1060For a couple of weeks I am able to test with a Analog TripleHead2Go --> 3x 26" widescreen --> 3840x1024For benchmarkflights I use Fraps and FSXMark07 ( flight over Seattle ) I found out that when using the TripleHead2Go I have much lower framerates than with the DualHead2GoResults ( 3x same flight ) DualHead2Go Min 30Max 46Av 39.42TripleHead2GoMin 11Max 25Avg 18.069When putting FSX on only 1 monitor the fps with the DualHead2Go are way higher too.That is 24 compared to 51 for lowest settings ! !Because I am at the point of buying this Analog TripleHead2Go or a Digital TripleHead2Go I would like to know what is going on here.All suggestions are welcome.

Gerrard- here is the math:2 monitors @ 3350x1060 pixels = 7,102,000 pixels per frame3 monitors @ 3840x1024 pixels = 11,796,480 pixels per frameWith 3 monitors, the computer is working 66% harder.But your av. frame rate data suggests the frame rate has only dropped 45.8%That's not a bad result.Alex Reid

Alex, the 3350x1060 is for 2 monitors, like the 3840x1024 is for 3 monitors. So not per monitor.The total of pixels are with the 3 monitor setup just a 15% extra.I think that it has to do with the the issue that my monitors are widescreen monitors, where the resolution of the Analog TH2Go is for 3:4 monitors.The image has to be converted to match the 16:9 monitors. That the pc has to do.The Digital DH2Go is capable of delivering 16:9 images. So no converting for the pc.Matrox has released new firmware for the Digital TH2Go so it is capable of handling 16:9 images too.What I will do is contact my usuall store and explain the situation.Then I will buy a Digital TH2Go , update the firmware and then test it. ( They allow to return hardware when having agreed on it ) I have the feeling that the framerates will be way better than.

Gerrard- Yes, my error- must have been asleep- your number appears correct. But the computer CPU has to generate those extra pixels- somewhat more when there are 3 monitors than for 2 monitors. So a significant drop in FPS is to be expected. But that isn't necessarily all bad. With a triple wide image, because your eyes/brain see only one very wide pic, frame rate can be lower than you might expect- yet still seem very smooth. If you sim with 2D mode (rather than virtual)- you should consider dual video cards for triple monitors, as an alternative to TH2Go. Alex Reid

According to Nick there are 2 things that play a role here :1 The spec resolution for a any of those cards.. 260, 275, 280, 285 and the DUAL 295 is 2560x1600. Anything above that resolution depends FIRMLY on the rest of the card spec to perform. So what performance does have the card left above this resolution.2 The Digital Edition of the TripleHead2Go supports far more resolution options than the original analog version. The issue can also effect what you are seeing too. So using three 16:9 monitors icw a three times 4:3 Matrox device makes things not fully compatible. Today I am going to test with a Digital TH2Go to see if it makes a difference.I will let you know the results.

Just had the chance to try with the digital TH2Go and what a difference.Framerates are back up ; just 5 fps lower than with the DH2Go.With the analog TH2Go the min benchmark framerate was 11 and average 18.With the digital TH2Go the min benchmark framerate was 20 and average 25. And remember that the resolution is higher now and also the DVI connections makes it all much sharper.It all seems to come down to the point that the digital version already supports widescereen resolutions and that with the analog version the pc has to convert 4:3 to 16:9.

Additional :After about 20 minutes in flight the framerates stated to drop till about 1/3 !I had the feeling that the graphics card could not follow the data speed anymore and the card stated to throttle.So this afternoon I wanted to buy myself a GTX285, but no store had one.Finally I ended up buying a GTX275 with 2 Gb memory ( EVGA GTDX275 FTW 2GB --> heavily overclocked by the factory ) I remembered Nick wrote about memory above 1Gb was only for multimonitor setup. The moment I started the pc with the analog TH2Go I could see that everything was sharper than with the GTX260benchmarkflights.To my surprise the framerates where about 10% higher than with the GTX295 and it was again a bit smoother.Now , even after having done some 1 hour flights eveything is still smooth.I think I am going to stay with the 275 card and will buy a digital TH2Go after 2 months.
