Macbook Pro Retina 13 late 2013 and external monitor

Hello,

I am looking for a confirmation.

I have Macbook Pro Retina 13 (late 2013), specs are here:MacBook Pro (Retina, 13-inch, Late 2013) - Technical Specifications

I am going to buy external monitor, keyboard and mouse to use my MacBook in clam shell.

I'm trying to understand the maximum external resolution I can support.

I see the HDMI supports up to 1080p, so I guess 1920x1080 maximum resolution. Do I have other alternatives? possibly, 1920x1200 in some way?

In case you think it's important, OS X Yosemite 10.10.5 is installed at the moment.

Thank you for your help.
