Can Microsoft RDC client use retina scale resolution on the MacBook Pro? I'm using the Microsoft Remote Desktop Connection tool with my MBP retina to connect to a Win7 system, but I can't get the resolution over 1440 x 900, even in full screen mode. Is this a limitation, or am I doing something wrong?

Changing the Retina display scaling didn't seem to make a difference.

I tried Cord instead, and while that seems to support other resolutions, the quality seems terrible.
Go to RDP settings, add the full screen resolution of your Mac (eg. 2880x1800 or a scaled version thereof, eg. 1920x1200, 2160x1350, ...).

Go to connection and choose that resolution and enable scaling.  Looks exactly like Jump
