My monitor is set up with screen resolution of 1920x1080. When I start Staad.Pro, it gives a message "Current screen resolution (1280x720) is less than the minimum recommended (1024x768), would you still like to run the application?"
Go to Control Panel\All Control Panel Items\Display\Screen Resolution;
check the setting "Make text and other items larger and smaller", keep it as default at smaller or medium. If you select Larger, STAAD.Pro will be chopped in the bottom and right section.
