If i understand, dual-monitor support will hopefully make it into version 2.6? I don’t know how long that will take, but for now, is the only solution to disable dual monitor support when testing in fullscreen?
I just tried a fullscreen GLFW app on a dual monitor configuration this week (ATI 9600 XP, DVI + VGA), and noticed that it used software rendering in fullscreen mode, but HW acceleration in windowed mode (even across two monitors at the same time).
I don’t have access to more than one monitor at home, so I can’t do much development/testing atm, which is one of the key reasons for the lack of proper multimonitor support in GLFW. I think I got the basic concept for supporting/selecting multiple monitors through the Win32 API (that’s what I intend to add to GLFW in the future), but I don’t know what forces the fullscreen mode to SW rendering on my card (this is at my job).
I would be very happy if someone with the resources and the will to test/code/fix this could help out. I’m a bit stuck.
I have dual-monitors, how can I help? I have basic experience with the Win32 API. I am certain I can look into the appropriate function calls and such. Is there a place you could suggest I start? If you just would like me to test, I can do that too.
That would be more than great! I suppose you could start by testing how GLFW works on a dual monitor system under different situations. Then (if you can reproduce the problems I was seeing on an ATI 9600 under Win XP) you could perhaps take a look at:
I suspect that the window opening code does something "wrong". There are a few differences in window flags for fullscreen mode and windowed mode, for instance.
I have an application that is trying to create a fullscreen (not windowed) that is 2944x1200 in size (that represents two monitors – one 1920x1200 and one 1024x768). I configured windows XP to treat the two monitors as one (extend windows onto second display). What GLFW seems to do is squash everything onto just the 1920x1200 monitor. Is this a limitation or is there something I can do to get it to render to the full 2944x1200 size?
