You just started a new job at a media production company. On the first day, Kumar drops off a new 27 inch monitor in your office and recommends you use the DisplayPort connector. Why would he make such a recommendation?

• DisplayPort natively interfaces with the VGA connector offering a great deal of flexibility.

• DisplayPort uses an analog signal, so it is less susceptible to electro-magnetic interference.

• DisplayPort supports higher resolutions and refresh rates compared to other connectors.

• DisplayPort is the only connector that supports audio and video signals simultaneously.

DisplayPort offers the highest data rate and is capable of delivering digital video and audio.

• DisplayPort is compatible with HDMI, DVI, and VGA so the video cable is interchangeable.

• DisplayPort uses a digital signal, not analog.

• DisplayPort is not natively compatible with HDMI, DVI, or VGA.

• DisplayPort offers the highest data rate and is capable of delivering digital video and audio.

Charanya decides it is time for an upgrade. She buys a new computer, a used 17-inch LCD monitor at a thrift shop, as well as a VGA splitter for screen duplication purposes and compatibility with the original VGA monitor. When she plugs in the monitors, the image on the LCD monitor is blurry. What are possible explanations for, and/or how could she rectify, this condition? Select two.

• The monitor was defective to begin with so she should return it right away and buy a new one.

• The monitor is not set to the native or recommended resolution hampering the image quality.

• Upgrading the VGA cable to a DVI, HDMI, or DisplayPort standard will improve the image quality.

• A 17-inch monitor is too small to support the higher resolution capabilities of new computers.

• Replace the video card; this is an indication of impending failure.

• Verify the video card is properly seated in the expansion slot.
