How can I put dual monitors on my new iMac

[JSmoove05]

Hey all been looking to add 2 24 led monitors to my current iMac. How does this even work and what do I need to do this? I have been looking but couldn't find anything.

If you have a 27" you will have two video outputs.

If you have a 21.5" you only have one video output so you will have to either use a USB video device (slow) or a Matrox DualHead to connect two monitors to one input

Use the two Thunderbolts ports with Mini DisplayPorts to DVI or DisplayPort adapters/cables. Monoprice offers such quite cheap.

The 2012 iMacs (the current ones, the OP seems to have one of) have two TB ports on the 21.5" and 27" model.

There are thunderbolt adapters available, it just depends on the inputs on the other monitors.

No, unless you get Thunderbolt capable displays. Those cables also cost more (49 USD per cable) than a Mini DisplayPort to DVI or HDMI or DisplayPort cable/adapter (can be had for 20 and less USD each via MonoPrice).

Is this the best way to connect it

The digital way is the way to go, unless you refer to Thunderbolt cables, in which case again, you need Thunderbolt capable displays.

and also how can I the monitors to stand upright instead of side ways.

If you mean, if you can rotate an the image that is displayed on a rotated display, yes you can, unless you mean something else.
