Multidisplay

Unity Engine

Hi All,
can anyone advise on multidisplay? I’ve got my displays set up correct, my own opengl code runs fine. I’ve tried to copy the unity example.

  1. I used this code
    Display.displays[ 0 ].Activate( 1920, 1080, 60 );
    if (Display.displays.Length > 1) Display.displays[ 1 ].Activate( 1920, 1080, 60 );

  2. I’ve turned off the start up res graphics quality from the player settings.

  3. I’ve tried executing with -multidisplay switch.

What I get is display 1 shows unity blue background, screen 2 shows “display 2” that’s set via the second scene camera.

I’m I missing anything? Thanks

Mudisplay is working for me on Linux but only if I launch it like this:

  1. Compile the game
  2. Run it
  3. In the pre-game configuration window select your full screen resolution, but check “Windowed” mode

Weird but this works for me. When the Display.displays[1].Activate(1920, 1080, 60) code runs, the second display activates and both automatically turn to full screen despite of the windowed setting.

Other than that my code is the same than yours but I don’t need to activate the display 0, it is by default.

Thanks I’ll try in morning.
I have got it partially running by use screen commands and setting windowed true, then after a few frames flipping to full screen. What’s odd is this only works about 1 in 5 times, the other 4 I only get full screen unity blue background, even though it’s set to winfiwed mode for up to 100s of frames. If I turn one screen off it always opens single in windowed mode.
Unity seem to have little documentation about this
