Hi, I have a multi-monitor setup (4), and have split the largest one vertically, giving me twice 1600x450 resolution, perfect. That monitor is also the leftmost in my setting.

When I extend a window that is in the top half of said monitor to the right, it extends into the next physical monitor. I cannot seem to extend that window to the lower virtual monitor instead. How do I go about doing that? thanks.

just re-read my question and maybe it came out too confusing. There is an application (StaffPad) that will show written music in just one written line, laid out horizontally. There is no way to "wrap" the music (vertically stack the lines), but it will cover any horizontal real estate it is given (I could stretch that system over all physical monitors I have).

I am attempting to "break" that continuous line/system into 2, for viewing on one single monitor, something the app itself won't do.
