to adjust the screen size fit to the monitor follow below steps.
1. click "Remote Desktop Connection" in windows menu.
2. you can see the dialog box. enter your IP.
3. In the dialog box, left bottom corner click "Show Options"
4. go to "Display" tab
5. in the "Display" tab you will find "Display Configuration"
6. drag the slider to fit your screen, most probably to "Large" side. So drag the slider to right.
