Yup, micro HDMI > HDMI cable, then connect to whatever you have handy for a display with HDMI input. A cheap TV would work fine.
Of course, if you want something better, look at getting a lilliput (on the low end) or maybe a smallHD or an EVF (Alphatron or Cineroid, for example)
Might be a little silly to splurge for one of those EVFs since they'd cost more than your camera did, but you can use them with other cameras too... *shrug*
Lilliput 7" is probably your best bet for cheap-ish, portable, and good enough monitoring. I just sold mine to a friend recently in anticipation of an upgrade later this year. I'm fairly certain is was this model:

You'll note, that comes with the HDMI cable you need to use it with your camera too, and it's got a nice collapsible sun hood and some other fairly nice features for the price.
The buddy I sold it to did a test with it on the second day after buying it, (battery charged for the entire first day) he said he got about 9hrs of operation from the one
battery.
EDIT: Scratch that, it comes with a MINI-HDMI to HMDI, not MICRO-HDMI to HDMI.. so you'd still need a cable, but for the price it's still a pretty nice monitor.
