DVI-D to VGA Conversion Options
When looking at DVI to VGA adapters, you will find that some are a few dollars while others cost more than a hundred dollars. The cheap ones will let you connect DVI-I to VGA, which is not a big deal, and often some monitors include cables for both. The expensive ones will convert DVI-D to VGA, as well as other signals, but why spend that much when you can just buy a new monitor?
The reason why DVI-D to VGA adapters cost so much is because they have to do more work and therefore more hardware is involved. It’s not like the wires are spliced inside of there. The DVI-D signal is digital whereas VGA is analog, so the digital video signal must be converted and downsized in order to make it work with VGA. Basically, the converter will take that high resolution, super-fast, super-clean digital video signal and strip out all that makes it goodlooking in order to fit on the old VGA standard. You lose image quality, sharpness, resolution, color palette, and more.
If you insist on converting DVI-D to VGA, or have some specific need to do so, your limited options are going to be pricey. For example, Newegg.com is selling a Startech brand DVI-D to VGA converter for $249. There is another device from Aten that takes VGA signals and converts them to DVI-D, which is kind of silly if you think about it, and that costs $219. Neither product has any user reviews, probably because they don’t sell too many of them. Just for comparison’s sake, you can buy a 23 inch LED widescreen monitor from Samsung for $219. Which would you rather have?
