Overscan for HDMI connections
 

I've got the latest Alpha 3 driver installed but in my display settings panel I don't have any option for adjusting the HDMI overscan the way I would if I was using the Thunderbolt to HDMI adapter. I'm hooked up to a Targus Dual (1 hdmi, 1 DVI) Is this a known issue?

We addressed this for Windows years ago, but I'm not sure we did it for Mac yet. I'll make sure it's in the queue although can't sure I'll update.
