Hi Macrumors,

I upgraded my 21.5" iMac to a 27" iMac (Slim i5), before I had 2x21.5" + 21.5" iMac (Triple Screen)

I currently have both 21.5" screens hooked up, it works great but was wondering if the new imac could handle pushing 3 x 1440p?

The next question is can I do this with normal DVI or HDMI? I know I probably need Duallink DVI or HDMI after version 1.3

Also do they have apps where you can deactivate certain monitors on the fly so if I start a game the iMac doesn't have to push unused pixels.

Good question...I plan on attempting the same thing when the iMac gets updated and I make my purchase to replace my 2007!

as far as I know, you can only do additional 2 screens at 1440 with the TBD. if not TBD, you're just limited to one non apple screen at 1440 and one screen via USB, but the res is limited to whatever USB is, so definitely not 1440.

A 2012 27" iMac will power 2x27" displays no problem.

Even the 2011 27" iMac can power 2x30" displays at 2560x1600.


If you're not using Apple displays then two mini-displayort -> Displayport adapters will do the job.
