Can we convert DVI to VGA or VGA to DVI?

Can I convert DVI to VGA or VGA to DVI?

Today's video technology is moving away from analog (VGA) for a digital connection formats (HDMIDVIDisplayPort).
This compact adapter provides support for resolutions up to 1920x1200, permitting you to require full advantage of your VGA monitor’s capabilities. a real plug-and-play resolution, the DVI-D to VGA adapter is straightforward to install; merely connect the DVI-D output port to the adapter exploitation the enclosed DVI cable, then connect a VGA monitor/projector to the VGA port on the adapter. However, there area unit still things wherever you would like to vary the show technologies; sometimes attributable to differing ports on a pc and show. Video signals is also tailored in either direction (both from DVI to VGA and from VGA to DVI), however there area unit bound limitations and expense variations.


Identifying which type of DVI connector you have is critical when determining how to connect DVI to VGA. The following images can help you determine which type of DVI port you have:

What is VGA ? 

VGA is an analog-only signal. DVI-D is a digital-only signal. These are not compatible. If your Viewsonic connector is truly DVI-D and not DVI-I, then the VGA-to-DVI-A cable will not work.


The DVI-to-VGA adapter will either be a cable or atiny low device (shown above). It permits a show device with a VGA connexion (input) to receive AN analog signal from either a DVI-A (analog only) or DVI-I (analog and digital) connexion hooked up to a computer's GPU. The converters square measure cheap and might be found occasional packaged  with video cards or at several on-line retailers for around $5.


There is conjointly the abundant less common situation wherever a GPU on AN older pc must send its signal to a more moderen show device that doesn't have a VGA connecter. during this case, a VGA-to-DVI convertor is needed to make a digital illustration of the analogsignal. These devices ar tougher to find and infrequently price upwards for $100. If you discover yourself during this state of affairs, we have a tendency to advocate upgrading your video card or shopping for a brand new pc.

Signal quality considerations

Please note that moving between these 2 technologies might cause you to expertise a loss of video quality. VGA, even in its highest resolution from SVGA, is barely capable of associate degree 800 x 600-pixel resolution. Therefore, if your laptop is causation out a better resolution DVI signal, it'll be restricted by the lower resolution of VGA. in addition, analog VGA signals square measure at risk of a loss of quality supported what their cables square measure product of and the way well they're place along.
