If the remote desktop has been configured with the correct amount of video RAM, the client can resize a remote desktop to match the size of the client window. The default configuration is 36MB of video RAM, which is comfortably more than minimum requirement of 16MB if you are not using 3D applications.

If you use a browser or Chrome device that has a high pixel density resolution, such as a Macbook with Retina Display or a Google Chromebook Pixel, you can set the remote desktop to use that resolution. Select the Toggle High Resolution Mode command from the drop-down menu located at the right end of the client menu bar. To display this menu bar, click the down-arrow on the tab at the top-center of the window.
