Which should I use DVI-D to VGA or VGA to DVI-D?

DVI-D to VGA converters connect new technology like a new DVD or Bluray player to aged equipment that have only VGA functionality such as an older monitor or projector.  DVI-D to VGA can be handled with several options.

The first is a device like the SCA-DVI-ANA. The SCA-DVI-ANA is a scalar converter dongle with a maximum resolution of 1920×1200.  The resolution is factory set to a specific resolution and once set cannot be changed.  For situations with variable resolutions, the SCA-DVI-ANA-UN is a simple device with dip switches which allow users to define the resolution based on the current installation.  These devices eliminate the need to buy new monitors and can be vital for installations with integrated locked down hardware.

Conversely, VGA to DVI-D converters upgrade analog video signals to digital, this is more likely to occur in timeworn infrastructure settings.  Quality analog to digital converters can automatically detect and display and output the correct VGA resolution on the digital DVI monitor.  The SCA-VGA-DVI has dual outputs (one VGA loop and one DVI-D Single link)which enables user to connect one VGA monitor and one DVI-D single link monitor for dual monitor applications.  This is also handy for confirming that the converter is getting a signal from the VGA source.  These devices also have a maximum resolution of 1920×1200.

Comparing different options for DVI-D to VGA Video Signal Conversion

Even though most people don’t give VGA a second thought any more, there are still plenty of VGA projectors and displays scattered throughout the corporate world. Whether the new computer comes with HDMI or Display Port, it is almost guaranteed to still have a DVI port and converting DVI-D to VGA is more cost effective than any other digital to analog converter.

There are two different DVI-D to VGA converter options available. The most common type that KVMSwitchTech sells is a SCA-DVI-ANA. It is a simple dongle that comes with a pre-programmed resolution. It supports a wide range of video resolutions (WUXGA|1900×1200|, UXGA|1600×1200|,SXGA|1280×1024|, XGA|1024×768|, SVGA |800×600|, VGA|640×480|), and some wide screen formats but you do need to specify the needed resolution. This works just fine in most situations, but for uses where the resolutions may have to change from display to display a better option is the SCA-DVI-ANA-UN. This converter has dip-switches that allow the user to specify from a wide range of resolutions and is ideal for use in situations when the resolution may not be known before hand.
