Mix and match This converter is ideal for applications with a mix of old and new equipment, such as older PC CPUs with just analog video output and newer digital displays. It supports VGA resolutions up to 1920 x 1200 @ 60 HZ. Plug-n-play Even better, this plug-n-play converter automatically calibrates for horizontal and vertical position on the DVI screen. You can also manually adjust the positioning. EDID management The converter includes EDID management, which is critical in VGA to DVI-D conversion. EDID management ensures that the correct settings are passed through. USB powered The converter is USB powered and requires no separate power adapter. Instead it draws less than 300 mA from a spare USB port on the computer. A USB pass-through port on the converter enables a low-powered USB device to be connected so the total number of USB ports remain available for other uses. Flash upgradeable The converter is flash upgradeable enabling custom EDID adjustments for non-standard operations. The upgrades are achieved via the USB port. Adjust the picture A Virtual Control Panel (VCP) app enables you to adjust the brightness, tone, and sharpness of the picture. You can also adjust the vertical and horizontal video alignment.
