Adder DVA Application

High quality VGA to DVI-D conversion

Adder DVA is a high quality VGA to DVI-D converter supporting most resolutions up to 1920 x 1200 @ 60Hz.

Auto calibration 

Adder DVA auto calibrates for horizontal and vertical position. Manual adjustment is also available through the Virtual Control Panel (VCP) app, if required.

EDID management

EDID management is a critical element in VGA/DVI-D conversion, to ensure the correct settings are passed to the computer's graphics card.

USB powered with pass through 

Adder DVA requires no separate power adapter and instead draws less than 300mA in operation from a spare USB port on the computer. A USB pass-through port is made available on the Adder DVA to allow a low-powered USB device to be connected; thus, the same total number of USB ports remain available for other uses.

Flash upgradeable

Adder DVA is flash upgradeable, allowing custom EDID adjustment for non-standard operations. Upgrades are achieved via the USB port.

Virtual control panel app over DDC-CI

Adder DVA is supplied with a Virtual Control Panel (VCP) app which allows brightness, tone and sharpness to be adjusted. Vertical and horizontal video alignment can also be adjusted, where necessary. The VCP app contains a test pattern to accurately display the changes. EDID management options can also be changed and the EDID's of the monitors can be displayed.
