I have a 15" Macbook Pro, late 2010, and a 21" iMac, late 2009. Can I link the iMac and use it with the Macbook Pro as a second display?
A friend may give me his desktop to use as a display. Believe it's a Dell. Would I be able to link that to either/both?
Both computers are running Mavericks.
Thanks,
Shayna

Yes, since OS X 10.9 Mavericks there is a function called Target Display Mode or short TDM. In short: this is a manner to use your iMac as screen for another Mac, not for PC's. You can connect your mac by miniDisplayport or Thunderbolt cables.
Unfortunately you need an 27-inch iMac Late 2009 or Mid 2010 to use mini display port, or an iMac-21 inch mid 2011 or iMac 27-inch Mid 2011 to use Thunderbolt.

You surely can use a Dell screen, if you've got a minidisplayport or thunderbolt port, then you can buy a minidisplayport to HDMI/VGA/DVI... Best way is to check out which connections you've got on your iMac and then search for an transformer. (You just can use an minidisplay cable in an thunderbolt port). A workaround could be an USB display adapter, but those don't have the best preformance...
Good luck!
