The DVI-D to VGA converter from BlackBox enables the connection of a computer with a DVI-D output to a conventional VGA monitor or a VGA projector. The device performs the necessary digital-to-analog conversion of the video signal, making video output on analog display devices possible. The conversion is powered by an external power supply, ensuring signal quality and stability.

Applications

The converter is designed for use in office environments, presentation rooms, or when using older monitors and projectors that feature a VGA connection. It serves as a bridge between modern graphics cards with DVI-D output and older display devices that cannot receive digital signals. The maximum resolution of 1920x1200 pixels enables clear display even on larger screens.

Functions and Features in Detail

The device features a DVI-D single-link female connector as input and an HD15 female connector (VGA) as output. The integrated virtual DDC function (Display Data Channel) converts the analog DDC signals from the VGA monitor into digital DDC signals for the DVI computer. This supports automatic adjustment of screen resolution and settings. The conversion is performed without requiring additional software or driver installation.

Technology Explained Simply

The video bandwidth of 170 MHz enables the transmission of high-resolution images with high color accuracy and minimal latency. The scan range includes horizontal frequencies from 22 to 95 kHz and vertical frequencies from 48 to 90 Hz, ensuring compatibility with various monitor frequencies. Power supply is provided via an external power adapter delivering 5 VDC, connected through a 5-VDC plug connector. The external power supply prevents signal interference that may occur when using USB or other internal power sources.

Compatibility and Accessories

The converter is compatible with DVI-D single-link outputs from graphics cards and computers. The output is via a VGA connector, which can be connected to standard VGA monitors and projectors. The package includes the converter, an external power supply, a short DVI-D video cable, and an instruction manual. The DVI-D cable is used to connect the computer to the converter.

Installation and Mounting

Installation involves turning off all connected devices, connecting the computer to the DVI-D input of the converter, connecting the VGA monitor to the VGA output, and then connecting the external power supply. After powering on the devices, automatic signal adjustment occurs via the integrated virtual DDC function. The connection cables are short, keeping the cabling tidy.

Advantages in Operation

The converter enables simple and reliable signal conversion without additional software or drivers. The external power supply ensures stable signal transmission. The maximum resolution of 1920x1200 pixels and the high video bandwidth of 170 MHz ensure clear and smooth video playback. The integrated DDC function supports automatic adjustment of screen settings, simplifying setup. The device is compact (2.5 cm height, 5.1 cm width, 8.3 cm depth) and lightweight (0.1 kg), making it easy to transport and install.
