Window size and render resolution not taken from .cfg file

[OOPz 10]

i am running A2 in windowed mode on a triple screen system (in 12:3 mode), the problem i am having is that every time i start A2 the window setup and resolution i configured previously resets to fill only the center screen at 50% 3D (pixel) resolution.

looking at my ArmA2OA.cfg i see that the correct values are indeed stored upon updating the settings in game:

Resolution_W=3838;

Resolution_H=1024;

winX=-1279;

winY=18;

winW=3838;

winH=1006;

winDefW=3838;

winDefH=1006;

Render_W=3838;

Render_H=1006;

I dont know for sure what all of these are, i believe the first two (Resolution W and H) can be ignored as they are the fullscreen mode (and im running windowed), but i forced them to the same res anyway, just to be sure.

winX + Y are, i believe the coordinates of the top left of the window, the numbers in the cfg are correct, but the game actually starts at 0,18

winW + H = width and height of the window, again, correct in the cfg but i actually get (i believe) 1280*1006 (1280*1024 - title bar)

winDef i have no clue about, but its set the same as everything else too.

and Render W + H is the actual width and height of the rendered 3D scene (which is then stretched to the window size), the cfg has the correct numbers, but upon starting A2, these always revert back to 50% (1919*503)

I know its not exactly life ruining to have to drag the left and right borders out then pull up the video options and set 100%, but i am getting a little tired of having to do it every single time i run the game :/

Im currently running A2 1.54.72888 (latest non-beta), but this has been happening since i first got triple screens setup, somewhere around the 1.03 or 4 era.

OS = Win7 Ultimate, 64bit

GPU = nvidia gts250 with drivers updated today.

If you'd like to know anything else about the system, just ask.

iv tracked it down, at least a bit... it appears that arma windows simply wont start with any coordinates outside the primary window, and i think it tries to maintain the % pixel res, not the values, thus when it is forced to 1/3 of its intended width on startup, it runs at the 100% res i set, which is 1280 pixels wide... when i then resize the window to be 3 times wider, it wants to run at 33%, but its lowest setting is 50%, so it uses that. :/

question: how´s it possible to run a triple screen setup with only one Nvidia GPU :confused:;

I thought that´d be only possible with later ATI cards (eyefinity).

[OOPz 10]

any other nvidia card can be used as a video out (tho, i suspect PCI-E is required to make it work efficiently).

Because its running windowed the main card does all the work and the secondary just allows you to hook up more screens (and work as an 'almost' dedicated physx unit too).

i suspect the same is true for an SLI rig (but im just using an old 9800), both cards would do the work as one unit, then the master sends the window content out via both.

if you want 3 wide and are looking to buy hardware for it, i strongly recommend nvidia over ATI unless you happen to already have display port monitors (which, basically nobody does), it works out a LOT cheaper.

(and trust me, you DO want 3 wide, especially if you like to fly helis, it makes a huge difference)
