You have a video card with a DB-15 connector and a DVI-D connector. Which combination of monitors can you connect without additional conversion units?

The correct answer is that you can connect both an analog CRT monitor and a digital LCD monitor using the video card's DB-15 connector and DVI-D connector without requiring additional conversion units.

Here's why this is the case:

The DB-15 connector, commonly known as a VGA connector, is designed for analog signals, which is suitable for connecting analog CRT monitors. This means that you can directly connect an analog CRT monitor to this port without needing any adapters or converters.

On the other hand, the DVI-D connector is specifically for digital signals and can directly connect to a digital LCD monitor. Digital LCD monitors typically come with DVI or HDMI connectors, and DVI-D is compatible with those monitors as it transmits a clean digital signal.

Since the video card has both types of connectors, it allows for flexibility in connecting different types of monitors simultaneously. Thus, both monitors can be utilized at the same time, making it possible to connect an analog CRT monitor via the DB-15 and a digital LCD monitor via the DVI-D directly to the same video card.
