Second Monitor Larger Resolution

[WOWBOX40]

Hm...think the monitor thingy has to do with your OS and even the nvidia settings. Somewhere in there it pulls up which is monitor 0 and 1. Then later on, if i recall, in isboxer, as you create a window layout, somewhere to the right was a small icon you could click to choose which monitor you wanted to use... 0, 1 etc. You will have to trial and error a few times, untill it uses the correct monitor you wanted to use, as it could be the oposite.. Im sure Lax, the author of isboxer, replied earlier in a thread about this...tried search some to find it, but no luck yet. It might have a solution for you, unless im remembering wrong.

Regarding the resolutions, you can google which resolution will have the same aspect ratio of your main monitor. This way, you input this number on your 4 slaves windows in isboxer, and mousebroadcasting will appear pretty much the same spot again, on all games.
