Sorry for bouncing an old topic but I have come across the same sort of issue on another project I am working on, I have 2 monitors side by side both are 1024 x 768 size and are set as independant monitors. I cannot make them span view, infact due to other software that has to run on the machine I cant alter any settings. Is there now any way or forcing GLB to draw to both screens if I set the screen resolution to 2048 x 768 with full screen options?
