The intensity of bad breath differs during the day, due to eating certain foods (such as garlic, onions, meat, fish, and cheese), obesity, smoking, and alcohol consumption. Since the mouth is exposed to less oxygen and is inactive during the night, the odor is usually worse upon awakening (morning breath).
DVI (Digital Visual Interface) is a specification created by the Digital Display Working Group (DDWG) to accommodate analog and digital monitors with a single connector.
This connector can only be used with a monitor that accepts digital signals (DVI-D or DVI-I monitor). DVI-A stands for DVI-analog and outputs analog signals only. It can only be used with a monitor that accepts analog signals (ie a VGA monitor with an adapter, a DVD-I monitor or a DVI-A monitor).
