Multi Monitor Setup And Windower Question

2 ways that I'm aware of. First, you can change your default monitor prior to starting the game. That will make it appear on that screen. You may also have to manually move the start bar out of the way as it can move to that screen as well when you swap primary screens.

Second. Type in window_toggleframe to the windower console. Or //window_toggleframe and the "border" around your borderless window will appear. You can then move the window where you want it to be and then type it again to make it disappear. Problem is that each time you type the command, it shifts the window by the size of the top of the border which makes it a huge pain in the arse to adjust properly. It would normally take me a few tries to get it exactly on the window properly.

After a very short time of dual boxing on different screens I switched back to dual boxing on the same screen since it just tended to get me confused as to which game instance I had up and caused me to screw up a lot as well as get more distracted. So I never actually found a better way, others may have better methods but these are the two I know of.

Slightly off but...does ffxi crash when you turn on tv?

It all depends on how your computer sees the monitor, if it's at the point that it disconnects the TV when it's turned off (It's a feature, and for the life of me I can't recall what it's called) then it's going to do that when you turn it on.

There's a way around it, but it's over the top a bit, and too much hassle for most people.
