Can the 2012 MBA drive a 1080p monitor without lag?

I demo'd the RMBP in-store today, and I have to say I'm disappointed with its performance. When using the Intel HD4000 gpu, the interface has some noticeable lag during animations (mission control, enter/exiting fullscreen mode, launchpad, etc). It gets worse when you increase the screen real estate via scaling options. So, obviously the integrated GPU cannot handle the retina resolution, which means you need to be using the discrete nvidia gpu for smooth performance (and that, unfortunately, kills battery life).

So, I gave the new base model MBA a try, and everything seemed great. My only concern, however, is I will be hooked up to an external 1920x1080 monitor most of the time and I'm worried if that will cause any UI lag like I witnessed on the RMBP. 1080p is a far cry from the 2880x1880 the HD4000 was trying to drive on the RMBP, but I figured I'd ask anyway to be sure.

I think even the 2009 Airs (maybe even earlier models) probably could do this, so yes, I am certain the 2012 Air can too. I think the Air supports driving up to a 2560x1440 display (27" Apple Cinema Display basically) flawlessly.

Yep, plenty of people run Thunderbolt Displays with the Air - I know two people with the 2011 model that do this. Only complaint they seem to have is its a *little* laggy sometimes, like when scrolling across desktops and stuff.

i ran 2011" 13" mba with the thunderbolt display, a bit not smooth when doing a mission control, but everything has been flawless.
