Running Dual Monitors

Does running dual monitors add stress on the gpu and cost your fps in most major games? If so running them at different resolutions increase stress? If anyone knows how this works can you please explain, Thanks.
 
for me multiple monitors doesnt slow me down at all..before doom 3 i caould run all five and not have any slow downs on system 1. used 3dmark 2003 and 2001 get in the 6000 range easy. fps doesnt suffer at all. doom 3 sound would glitch with all my monitors on though.
 
I havent ever had performance issues running dualies but if you are worried about that you could always run out and buy a $20 PCI card to run a second monitor off of, at one point i ran 6 monitors on this machine with everything from an ati rage to an S3 Trio64... LOL
as long as you have a good video card and RAM you shouldnt have performance issues anyway though.
 
i have my desktop extended permanently to my tv and i never have performance issues with games aside from the fact my pc is starting to show it's age
 
there's no performance hit...except the extra cpu cycles to drive the second display which is negligible...some games freak out with multiple monitors...but not many...and they either work or they don't....there's no degraded performance, it'll either be fine or complete shit...you'll know right away if you need to disable a monitor...

For nvidia cards there is also a setting you change in the config to go to single monitor compatibility mode which cures all the wierdness...but slows down some stuff in 2d...
 
I've been running dual monitors on a GF4 Ti 4400 for a while and I've always done something really simple when playing games: I disable the secondary monitor.

I do this for a couple of reasons, but mostly because there are a fair few games out there that cannot cope with "two desktops" so they either cause the display to "spaz out" or it just crashes the game, or they cannot correctly set the screen boundaries so when the mouse moves onto the secondary monitor and you click it causes the game to minimize (GTA3 is an example of this, at least in my experience)

I've been using a utility called Ultramon ( http://www.realtimesoft.com/ultramon/ ) for a while now, it sits in the task tray and you can customise the right-click menu. So when I want to play a game I just go... right-click in system tray, Disable Secondary then load the game. When I quit and want dual monitors back I just right-click and do Enable Secondary, pretty simple.

Something interesting I noticed recently, which came from this tech-report post - http://techreport.com/news_archive_overview.x/2004/8/2 - Read the "Careful with the dual displays" section... in theory dual displays shouldn't cause a problem with games, but in practice they often do and there is a case in point.
