How it works.The VGA/DVI to DVI-D Converter digitizes the incoming signal and stores it in an internal video memory before displaying the video in a compatible format. The converter features more than 160 preset video formats stored in its internal table, and it enables you to configure DDC for optimizing source-to-display communications.If the input signal corresponds to one of these formats, the signal will be automatically detected by the converter and the picture will be displayed. Or you can manually select the most suitable video mode, even if you don't know the input signal.Optimizing the picture settings for your input signal is easy. Simply use the included IR remote controller to navigate through an on-screen display (OSD) menu of controls for resolutions as well as video-correction tools. Adjust color, pixel clock, pixel phase, aspect ratio, and other settings, and set it up to scale the picture to the maximum value automatically. Or manually select non-standard and unsupported video modes. To converter includes an adapter cable for VGA connections to its DVI-I port. You can also use the DVI input without the cable to attach a DVI-I device and scale the digital video for output on the DVI-D display.For larger video applications with multiple display conversions, we offer a 19" rackmount kit, which holds up to four ACS411A-R2 devices in 1U of space.
