making my TV a primary a display is hardly an option for me since I have to use the PC for regular usages as well (internet, office, etc.), I am using DualView exactly for the matter of Media Center only- and it serves me well, I have to say. When you say that MAME allows to select which display to use, and my games are all MAME Roms, invoked by mame.exe, then what parameter do I have to set to make it show on my secondary display?
