Am I doing something wrong? The dynamic update resolution works for win8.1. But it only works in the MS Store version of RDP. The desktop version of RDP does not reset the resolution in the host like the store app does. 

Am I missing something? The release notes from RDP 8.1 says you should be able to resize the window and resolution in the host will adjust accordingly?

Hi,

Yes, dynamically resolution is available in Windows 8.1. Resolution is set at connect time and can be updated when the client-side resolution changes while the app is in full screen mode, or when the app transitions from windowed mode to full screen, and there is no need to do a complete reconnect of the session.

Where did you install the "desktop version of RDP"?

Best regards,

Susie
