external monitor

[2macman]

I have a 2010 27 iMac.

I am about to get a 24 inch Samsung LED for an external monitor.
I will use the DVI cable to connect.

Will using such a large external monitor slow down anything or have any ill effects?

Nope. Those iMacs have more than enough graphics grunt to handle two monitors for just about anything that isn't so heavy duty you'd want to be running a Mac Pro anyway.

Even running lower-end graphics most computers Apple sells probably perform fine with two monitors, so long as you're not running Motion or something similarly extreme. My 4-year-old MBP had no issue driving its 17" built-in plus a 1080p TV, and I didn't even have any significant problems running an archaic G3 PowerBook with an internal and external monitor simultaneously.
