I use an app named
Sizer to set the window size on my separate and windowed clients, it can sit in the systray on Windows and you get fully customizable resolutions, etc. Sizer does not move the clients to the correct screen automatically but I'm sure there are other window managers that can do that as well if needed, I just throw my EVE clients around manually or by hitting the 'special' buttons sitting to the left of the min/max/close buttons on every window. Check the screenshot below. That particular app in turn is named
UltraMon and offers a ton of other functions as well, such as the ability to extended the systray onto the secondary screens, etc.
Full screenshot spanning 2 x screens with the EVE client set to the custom res "NEC H Full 1900x1030 Float" from the custom popup in systray. (L screen native 1920x1080, R screen native 1680x1050).
The Sizer is a minimalistic app makes stuff simpler and gives you a bit of control if you fiddle a lot with swivel screens, resolutions and various window sizes basicly. Hope this helps out.
