symptom
When you start the Remote Desktop Connection client, you'll find the same window with the remote desktop size or smaller than the desktop [after] to maximize the full screen or not, rather than full-screen; but the "maximize" button to display the window is in a maximized state. If you click the "maximize" button, the window does not enter full-screen mode to normal, but the reduction was slightly smaller than the remote desktop.
solution:
When you start remote desktop, remote connection options click the window below. -> Display tab -> adjust to full screen display configuration. Connection can!
