VGA to DVI converter

Post » Tue May 17, 2011 3:58 am

Ok so my friend is taking back the monitor he borrowed me, I am borrowing another one from my sister until I can afford a nice flat screen LCD monitor, One problem, the Monitor is VGA only, and my Computer only has a spot for DVI (On the video card), How well does something like this work?

Or there anywhere to get a cheap DVI monitor for around 50-60 dollars?

Thankyou

They work plenty well enough, and they are only a couple dollars.

Maybe second-hand used on ebay/amazon :shrug: Almost definitely not new. I'd also be plain weary of anyone offering one under $60 brand new. Probably would explode in your face when you plug it in.

I will probably just buy the converter then, I just wanted to make sure they work good enough.

A converter came with my card and I never had any trouble with it. Works fine.

There will be some interference and image degradation due to the image being converted from a digital signal to an anologue signal. But probably not enough for you to notice unless you sit only 20 centimetres from the screen. :)

Such a tiny monitor, lol. Better than not having a comp. though.

I have a monitor connected trough one of those. Ridiculously enough, it's a LCD monitor :lmao: A cheap one with only a VGA input. Never really noticed an image quality difference between it and the HDTV connected via HDMI (if running them at same resolution of 1366x768) :shrug:

The adapter doesn't convert anolog to digital. DVI ports on most graphics card are DVI-I (means it can route signals for both anolog and digital).

No but the signal must be converted from digital to anolog (as per what I wrote). There is a DAC chip pre the DVI-I port on the video card wich works with the GPU to decide what format the detected monitor requires.

VGA connectors and cables carry anolog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. I the old days, an now still on large live events, we use what is called an RGBHV data cable wich is about 3 times as thick and contains 5 shielded coaxial cables with bayonet (BNC) connectors on either end. Usually colored red, green, blue, white(H), and black or yellow(V). This used to be the only way of achieving high quality data projection. Now the industry is moving to DVI-D with fibre optic cables.

So If the monitor only has a VGA input, then the signal must be converted to anolog in order to be displayed on a CRT monitor, wich is what I'm assuming the OP is now using.
