Or himhimHow do he do it....?

This is not correct: With TH2Go your video card drives a single display window of size 3x the horizontal screen resolution of the individual screens in your setup. Because the pixel count is now 3x the pixel count of a single screen, the GPU will have to work *about* 3x harder.Cheers,- jahman.

Jahman- My understanding of TH2GO is that it simply blows up (a single monitor image of a single view) to triple size and spits this out to be spread over 3 monitors. I believe this causes a coarseness of image which then leads simmers to want to use a higher resolution and I think this is why a CPU might have to work harder. But leaving processor resolution constant, the computer CPU continues to compute only the pixels for a single view and so has NO extra work to do. Frame rate is computed by the CPU and so it does not change. TH2Go presumably triples those pixels so that the pic can be spread across 3 monitors- but no new/different pixels are created. With the wider pic, complete lines (ie lots of pixels) have to be deleted by TH2GO from top and bottom of the whole thing to fit the new wide format. (This leads users to apply Zoom Out to achieve the same visual perspective- but at the cost of diminished distance perception.)I have heard nothing to suggest that the TH2GO cannot keep up to the main processor CPU.However if you display 3 DIFFERENT views via multiple GPUs, (LFwd,Fwd,RFwd), the CPU does work harder and FPS declines somewhat depending on the capability of the processor.But then I'm far from being a tech so comments are welcome!Alex Reid

i thinking to buy a GTX470 and a Tripelhead2go because windows will see the 3 monitors as 1 monitor and i can choose between 1 large view or 1 wide viewSo until i seriously being told anything better i will do that

Alex,The TH2Go displays a single, very wide image accross the 3 monitors. The horizontal pixel count is equal to 3x the horizontal pixel count of each monitor in the setup. For example, of you have 3 monitors of 1920 x 1080, then the TH2Go will have your video card deliver a *single* image of size 3 x 1920 = 5760 pixels times 1080 pixels vertical. See last entry here.So there is no image stretching, but rather image chopping: The single huge image that is generated by the video card is chopped into three horizontal pieces by the TH2Go and then each piece is sent separately to each one of your three monitors.From FSX's point-of-view there is a single image, which is great for VC and of course for panning.Cheers,- jahman.

I think we are both on the same track but seeing it from different perspectives.My point was simply that TH displays only View Forward over 3 monitors whereas with 2 GPUs you can display 3 completely different synched views- Left Forward, Forward, Right Forward thus producing an horizon of about 145º when bezels are factored in. The TH single view can be zoomed out to increase the FOV from normal 45º to about 135º but at a significant price of distortion of distance perception. Regards Alex Reid

"The TH single view can be zoomed out to increase the FOV from normal 45º to about 135º but at a significant price of distortion of distance perception." Can this be done without increase the distance perceptionAnd you can even with only 1 monitor view 3 difference viewsand how can the bezel be factored ini will try to send a picture showing my attempts and wishes (Time in Denmark right now: 11.00 PM)

patrickbc- Any use of Zoom will affect distance perception and consequently also, your speed will SEEM to change. As you increase apparent distance by Zooming Out, the speed will SEEM to increase also. (Time remains constant in the simulator even when you Zoom. So if the distance to a runway appears to increase due to zooming so also will your speed apparently increase to cover the same stretch of ground on your approach.) Not conducive to smooth approaches!-----Re your request for screenshots-It is very difficult to get good screenshots of multi monitors since the process displays the monitors in a flat plane even though the outer mons are angled toward you at about 40º. Additionally, screen shots remove the bezels and show the images side by side. In fact, the real monitors are separated by the bezels thus hiding a slice of scenery.However here are two that may illustrate our discussion.This shows a little bending of horizon in the outer views- I believe the Bonanza had a slight pitch up at that moment. With the panel occupying the lower half, the amount of bend visible is limited. Here the bend is quite visible as the plane both rolls AND pitches. This shot is over Phoenix USA, chasing hot air balloons.I'm not a pilot but I think the first pic is more accurate to real airplanes with the cockpit panel occupying about half of the piot's entire perspective. What we need from developers is an integrated 3 piece panel rather than add-on popups which while making those controls available at all times, doesn't really reflect the true appearance of the whole instrument panel. Virtual panels are superior for appearance and accuracy- BUT you then have to consequently pan and zoom to see/read a particular gauge or switch and each time it may be in a different spot on the monitor. This is why pan/zoom is not used in real life Flight Training Devices.I would suggest you talk to your local computer shop, describe what you want to accomplish and they can advise better than our general and varied answers here.Regards Alex ReidPS- yes you can display 3 views on one monitor- but it needs to be a large one to be able to read the instruments. Also you adjust for bezel width in Panel Config for FS9and I believe, in the CAMERA section for FSX.

Yes, I see it now, we are both saying the same thing from a different POV! Apologies for the BW...Cheers,- jahman.

hmmmmm........How do you get the horisont to hang together.......And does windows (With the TH2GO) only see the 3 monitors as 1 monitor because when you are in fullscreen mode you can't drag the window over 3 monitors

Some shoots from my test on 1 monitor why does the horisont do like that, but although it looks bad it is pretty cool but how do i get it better?

hmmmmm........How do you get the horisont to hang together.......

You need to activate Matrox Bezel Management or

to automatically hides the pixels that would be behind the four vertical bezels. Then the horizons ins all three monitors will align.

And does windows (With the TH2GO) only see the 3 monitors as 1 monitor because when you are in fullscreen mode you can't drag the window over 3 monitors

Windows only sees one monitor, FSX only sees one monitor. With bezel management activated, you will only see one monitor!Cheers,- jahman.

The original poster asked about the impact of TH2go on performance. I have a TH2go digital, and yes, there is some performance hit.TH2go mimicks a larger, higher resolution monitor. In my case, that's 3840x1024. If you could buy a single monitor in that resolution, it would understandably affect performance. The higher the resolution, the harder the computer has to work. I do not see 1/3 the performance using TH2go, but there is a hit.TH2go increases the FOV. The FOV on a single 1280x1024 screen is not simply spread out over the 3 screens at 3840x1024. For an exhaustive discussion on this aspect of TH2go, with photos, see this previous thread.Another solution, besides Eyefinity and nVidia Surround, is WideView, with multiple CPU's. This allows the performance hit of multiple 3D views to be spread over multiple CPU's/GPU's. If you have the money, that is.Hope this helps.Noel W

That's exactly my experience regarding triplehead2go as well, which is expected as you're then using a much higher resolution than normal, and in a way that the hardware wasn't really optimized for.As already stated, the description "TH2Go presumably triples those pixels so that the pic can be spread across 3 monitors- but no new/different pixels are created" is completely incorrect.If we're talking performance only, the major difference between triplehead and eyefinity/surround mode is that for the latter the hardware (graphics card) and driver are higly optimized for very high resolutions and they perform extremely well. They perform extremely well even in an old beast like FSX since FSX really has nothing to do with it and doesn't even have to know anything about it - to FSX it simply looks like an unusually large monitor (just like triplehead2go), while the hardware is still effectively utilized behind the scenes. That's why statements like "FSX does not support SLI/crossfire" or "FSX does not perform well with SLI/crossfire" that you see almost daily in these forums are not always entirely true.I've tried eyefinity, nvidia surround mode, multiple views within fsx, triplehead2go digital, and wideview. They all have their pros and cons (well, some have only cons) but performance-wise my personal opinionis that eyefinity/surround mode are very equal and take the first place, shortly followed by triplehead2go. With modern hardware and a well configured system using Bojote's tweaks, performance really shouldn'tbe an issue anymore unless you're doing something terribly wrong anyway. Using multiple monitors can be a bit more complex than just the performance issue though.

Has Surround gaming Bezel compatitionWith Bezel compatition and GTX470 x2 does WIndows only see 1 monitor?Is GTX470 x2 better than TH2GO (Performance, look, and severity?)How much does GTX470 expands the FOV (With 1 view only)How much does TH2GO expands the FOV (With 1 view only)will You still recommand 2x GTX470 for both 1 view and 3 views (Performance, look, severity?)Thank you !!!!
