Hi Chintan,
The way to do with is with environment variables read by SDL.
setting the environment variable
SDL_VIDEO_WINDOW_POS="0,0"
will cause the VE window to be draw in the upper left of your left
display. (This assumes your multi-monitor setup acts like a single
stretched display.)
There's an entry in the FAQ: http://www.visionegg.org/Documentation/FAQ
(See "How do I specify where on my screen the display should go? If I
create a window, I know how to direct the graphics to a certain location
within that window, but how do I set the position of the window itself?" )
Also, there are various emails to this archive in the past years about
it. See the thread at
