[visionegg] Re: directing VE fullscreen when using two displays (not cloned displayed)

Hi Chao,
That's a great idea, thanks!
I will try it out and report on the results.

 Hi Ted,

You may try this: (assuming two 1024x768 monitor settings)

1. Set XP's 2nd monitor position to a certain value, say (1024,0) (i.e.,
right to the 1st)

2. Set related VE configuration parameters
    # Screen width/height
    VISIONEGG_SCREEN_W = 1024
    VISIONEGG_SCREEN_H = 768

    # Use fullscreen?
    VISIONEGG_FULLSCREEN = 0

    # Open a window without a surrounding frame?
    VISIONEGG_FRAMELESS_WINDOW = 1

3. Add a few lines to your VE code
    inport os

    # set border-less window position to (0,0) on the secondary display
    os.environ['SDL_VIDEO_WINDOW_POS']="1024,0"

These will deliver your stimulus to the 2nd monitor in a frame-less window
(fake full screen).

Best,
Chao

(not cloned displayed)

Hello,
We are trying to use Vision Egg in a two display setup, so that
when VE is started up it goes to full screen on the secondary
display only (nothing on the primary scree).  By primary & secondary,
i'm referring to the Windows XP display settings, in which those
numbers can be assigned.  VE needs to be the secondary screen
because of requirements of our eye-tracking software.
My question is: is there a VE command which will designate which
of the two screens the viewport will get displayed to?

I was unable to find anything in the archive or code docs
addressing my question, but if it has been covered, please direct
me.

Thanks!
