VGA to DVI-D, USB powered video converter
• Analog to digital video conversion up to 1920x1200 (165MHz max. pixel frequency)
• EDID management to ensure clean operation
• Adjustment control for alignment, tone, sharpness and brightness
• USB powered with USB feed through
DVA (Digital Video Adapter) is a high performance VGA to DVI-D video converter that transforms analog signals to digital, conforming to the DVI 1.0 standard. Placed in-line and USB powered this solution fits well with the AdderLink Infinity range of products. It converts VGA signals, up to 1920x1200 @ 60Hz, into a DVI standard equivalent.
Installation is quick and easy: DVA attaches to the analogue video output port on your computer and gains its power from a spare USB port. You then connect your DVI video display to the digital video output port on the DVA module - and that's it. No special drivers are required and operation is totally transparent to the devices and to you, the user.
DVA can support the majority of video modes defined by VESA DMT with vertical refresh rates of between 56Hz and 75Hz up to 1920x1200 @ 60Hz (reduced blanking). Refresh rates of 85Hz and 120Hz are not supported.
DVA auto calibrates for horizontal and vertical position. Manual adjustment is also available through the Virtual Control Panel (VCP) app, if required.
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
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 DVA to allow a low-powered USB device to be connected; thus, the same total number of USB ports remain available for other uses.
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
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.
