How to View Full Screen using Remote Desktop Connection

I'm brand new to Mac; accessing work computer from home via Remote Desktop Connection. Windows 7 on both ends. Using Mac/Parallels, when I view the remote screen, only part of it displays, requiring continual readjustment with two sets of scrollbars - for both Windows and whatever program I'm using. This is cutting WAY into productivity. I've perused this forum, read a hint to set View in Parallels to Fullscreen. I tried it, it made a little bit more of the remote screen viewable, but didn't affect the need to use the scrollbars to view the various parts of what's onscreen.

I'm hoping I've described this sufficiently so someone can help me make whatever adjustment is necessary to view the full screen on my remote computer.

Thanks very much in advance.
