Issue
One or more screens in ConstructConnect Takeoff don't seem to fit on your screen, even though your monitor meets or exceeds System Requirements.
Discussion
ConstructConnect Takeoff is a responsive user interface meaning it tries to resize to accommodate various screen sizes. However, there is a minimum screen size required and if you have your monitor configured in a particular way, some of the screen may get cut off.
Like all Windows applications, ConstructConnect Takeoff's user interface relies on the Window's DPI settings to size its screen. If your DPI is set to Medium or Large (as in the screenshot below) and you are not using a high enough resolution (this is dependent on the size of your monitor, your video adapter, the amount of memory available for video - all things outside our control), the program may not fit on your display.
Resolution
There are two things you can do. Set your DPI to "Smaller - 100% (default"). This is the settings applications are designed around and are guaranteed to work on when the PC is set to a resolution indicated in the system requirements.
Increase your screen's resolution, if possible. You adjust resolution a bit differently in every version of Windows, but you can typically find this setting by right-clicking on the desktop or by opening Control Panel or Settings and choosing "Display".
Increase your Resolution until you find a happy medium between seeing the entire ConstructConnect Takeoff interface and legibility.
