Because each monitor has a different observation angle to the scenery. Probably the entire scene is calculated 3 times. The biggest disadvantage is, that the graphics engine has to calculate the geometry at least for some overlapping objects 3 times for a frame. This setup needs to have the option 'Full Screen' to be checked. This single desktop technology is used by the Matrox tripple head. The frame rate is limited only by the entire number of pixels on the desktop. Internally you will get a better frame rate because the graphics engine calculates only one geometry for a frame. The position of the observer in front of the monitors is not bound to a fixed position. There is only a limited fish eye effect if no extreme zoom out is used. The field of view is normally limited to a natural angle. The advantage of a single desktop is that the scenery is displayed more naturally. To understand edge blending, see the attached image. DCS takes the three monitors internally as one large monitor. The second disadvantage is, no edge blending is possible, because there is no variable for it. This can only be produced by zooming out in the cockpit by getting a fish eye result. A 180° field of view is not possible in a natural way. You could even take one large monitor to get the same result. The disadvantage is, that only one flat projection plane exists. It explains the differences in field of view and angular distortion Which solution is finally taken depends on the individual special liking. To clarify the difference between single dektop and 3 camera setup, I have made a small drawing. Really nice nice sim space ! how does it cost you if i can ask? WOW Towsim !!! the only thing i have equal to you is the wireless telephone ( i think siemens ) on the right.

The maximum I had was 30 frames in an airborn situation at high altitude. If I have a scenery with twilight illumination and a lot of objects, the frame rate drops below 10 frames. The performance of the graphics is at the limits. The resolution and aspect ratio needs probably to be set manually to the values. As you can see in the 'options' image, the 'full screen' is not checked. Divide 'Monitor frame width' by 'visible image width' and you get your individual edge blending value. Measure the overall width of a monitor including the frame and then the width of your visible image area. The value I use (f 1.09) must be calculated individually for your type of monitor. The entry of 'viewDx = -1.09' and 'viewDx = 1.09' compensates the monitor frame. The only additional definitions in DCSW was, to modify the a for the edge blending. The usable desktop spans over all four monitors. The Desktop is defined as 5760x1200 and the main monitor is the most left of the three. It was not possible for me to find any combination with Eyefinity which would fulfill my requirements. Whereby the forth monitor is connected to an additional NVIDIA graphics adapter. I arranged 3 of my monitors in a row and a forth in the mid below. It was a hard work to get my normal arrangement back after experimenting with Ifinity. The only service I use is done in' CCC Desktop management', displayed in the CCC image below. So obviously, I do not use Eyefinity in my environment. I just tried to find out how Eyefinity works. Option D: Resolution = 5760 x 1200 / Aspect Ratio = 4.8 / Monitors 3 Screens / Fullscreen = Checked (You need to have Fullscreen checked or the screen will be cutoff on the left and right) Option C: Resolution = 5760 x 1200 / Aspect Ratio = 4.8 / Monitors 1 Screen / Fullscreen = Checked (You need to have Fullscreen checked or the screen will be cutoff on the left and right) Option B: Resolution = 6048 x 1200 / Aspect Ratio = 5.04 / Monitors 3 Screens / Fullscreen = Unchecked (You need to have Fullscreen unchecked or you won't be able to select quit / cancel buttons on screen) Option A: Resolution = 6048 x 1200 / Aspect Ratio = 5.04 / Monitors 1 Screen / Fullscreen = Unchecked (You need to have Fullscreen unchecked or you won't be able to select quit / cancel buttons on screen) Last night I wanted to compile screenshots of each of the following DCS modules: P-51D, Ka-50, A-10C, and Su-25T. My setup is three Dell U2412M monitors in Eyefinity (screenshot) and MSI Frozr III 7950 video card. I would like to thank all of you for the quick replies and help I received via this forum.
