Known Issues

The STRUCT used for DEVMODE does not contain the UNION needed for setting position so if your displays aren't oriented in 1 - 2 - 3 order, adding them back might put them out-of-order. I'm trying to figure out how to get this to work properly as it requires unsafe code which throws a memory access violation when trying to set the position.
