Thanks glenn..
i've been through all of your links in the past :) and i know my issue is due to using 2 stitched monitors rather than 3..
However.
1. configuring the monitors individually from within XPlane using lateral view angles, while it looks and functions great.. my frame rate is 20-30% lower.. so that is NOT an option
2. my 2 monitors together are wide enough.. adding a 3rd monitor in the "stitch" is really not an option.. i fly GA stuff and my field of view with the two wide screens is pretty decent (see my screenshot)
3. even if i add a 3rd monitor.. i would still like to have the dialogues moved away from the center, as i fly on one monitor, and use the others for peripheral vision (as the yoke is not in the center of the plane in my case.. kinda like when driving a car!)
the idea is to find the setting from deep within the xplane files, the values that dictate the location of the windows... as i'm pretty certain that isn't hardcoded..
i do have a smaller 3rd screen that i'll be configuring as a separate 2D monitor with some instruments on it, so that won't help with the stitching issue...
nonetheless, i appreciate your help! always good to bounce ideas back and forth
