I’d tried that. It didn’t help. The problem I’m having stems from the screens being different widths. But BeamNG wants to make the images meant to span all three screens the same width. This means that the center screen’s image is a few inches narrower than the screen, and the “seam” where it thinks the bezel would be isn’t at the edge of the screen. So the images meant for the side monitors start on the outer couple of inches of each side of the center monitor. I hope I’m explaining that well enough. Imagine if these were three monitors, all meant to display 12345 and the bezels are these symbols: || so this is what is happening with side monitor - center monitor - side monitor:
| 1 2 3 4 || 5 1 2 3 4 5 1 || 2 3 4 5 |
the end of the left monitor image is at the left outer edge of the center monitor, and the start of the right monitor image is at the right outer edge of the center monitor. This creates an odd seam where the outer images meet the center image at a weird angle in the center monitor.
If there was a config or setting file that can be edited to tell the game the widths of the monitors, or the resolution of each, this problem would be solved. Again, dragging a windowed instance of the game across three screens causes weird distortion, and the AMD Eyefinity causes a downgrade of the center monitor’s resolution so it looks like the image has been stretched out.
