hi everyone

well 2 days ago I was cleaning the dust around my computer, and when I reached behind my LCD I noticed that I have a DVI that I am not using, so I got interested and started looking the internet, now so far what I have been reading is that DVI delivers a bit better quality improvement, so I went to the nearby store to get a DVI cable, but the guy said that its 35$ so I didnt buy it....

my question is, is it worth spending 35$ on a cable and changing from VGA to DVI? what do you guys think?
Does your Graphic card have a DVI port? Does your LCD have a DVI port? If both are yes, only then you can use the DVI connection. Well if your LCD has a DVI port, then you should have got a DVI cable with it when you bought it.

Is a DVI cable worth 35$? Not really.
On my personal experience no. Its exactly the same on low resolutions (less than 1680x1050), unless your on a huge HDTV with a connected HTPC or something a DVI or HDMI are recommended.

I myself did some tests on both with a 22inch lcd screen and the results were exactly the same.

Technically, VGA delivers an analog signal through the cable and can be threatened with electrical interferences and stuff but that's somehow rare and is mostly found if you are using a really long cable.
The DVI just sends digital data (binary) through the cable and electrical interferences don't affect it.

Also vga are aimed at maximum resolution of 2053 x 1536, anything below that and the picture will be fine.

By the way you can find cheaper DVI cables maybe around 10 to 15$. I remember virgin megastores and radioshack had some cheap ones, you should look there.
Radioshack had a DVI cabel for a LL160,000! Something about no gas, gold-plated, and 720p.
There are a lot of articles about how senseless it is to pay too much for DVI or HDMI cables...

I did not notice any difference between using a VGA or a DVI cable on my 17" LCD with a resolution of 1280x1024
I do not notice the difference on 1900x1280 22" benq.
The DVI cable can be get at Compuworld for 10000 or less I think.
If you use DVI instead of VGA, you most probably will not notice any difference with your bare eyes. Yet if you have a problem with your monitor, you might want to try DVI to see if it solves it.

If my memory serves me well, the DVI standard allows for both methods of transfer: binary and analog. That is why DVI to VGA adapters are possible and can be bought - obviously they will only work for monitors using DVI in the analog mode. I think cheap and old monitors use DVI as an analog interface, so I think it's basically the same then VGA.

yeah they both have DVI but I bought my LCD refurbished so I didnt get dvi cable :/
also my 19" LCD is at a 1440x900 so I guess I wont notice a difference...
