Multi-Monitor Display

[Bulba]

My primary monitor has a cheesy intel 810 whilst the secondary display device has a meaty Riva tnt2 PCI.However out of 30 games only Aliens vs Predator and Shogun give me the chance to switch the gameplay to my second monitor. There is no possible way to give the secondary the card and forget the primary, trust me i've tried, and games such as system shock 2 are not detecting the secondary display driver, is there any known reason why shock 2 wont detect it whilst avp does?
Do you know of any other games that give the chance to change the display device?

I am surprised that you cannot disable the intel 810 (that an on-board graphics bit I guess) but won't argue as I an't tell you how to :)
You say that some games don't detect the 2nd display driver, were they installed before the TNT2 card was? Maybe a re-install will solve it. Some games have set-up routines that are seperate to the game itself (i.e. not in the options menu within the game), so are there any set-up programmes to run for the games?

Just lobbing in a few thoughts...
