Does the adapter convert the signal as well as a dedicated vga output that comes on video cards that support have 1dvi-i and 1 vga output. DVI-I has the exact same analog signals present as VGA. The adapter just carries the signal to the right pins. If youi google "dvi-i pinout" and "vga pinout" you'll find diagrams of both right quick. THis is an issue because as I said ulimately I would like to have 2 monitors hooked to the 2 dvi-i outputs on a card. Also Suggestions for card in 180-250 dollar range nvidia or otherwise. Thanks There are several dual-dvi GeforceFX 5700 boards in that price range.

dvi-i vs anolog output to drive crt monitor - quality
Well here is the deal.

Is it right to assume the text quality would be the same when hooking up a dvi capable lcd monitor to the dvi-i output? Are you just refering to the text output on the anolog portion of the dvi-i connector when hooking up the Crt monitor to that? Thanks |

The DVI socket contains a normal VGA signal - the adaptor simply makes the connection fit. Does the adapter convert the signal No need - it's already a standard VGA signal. The digital DVI part, is carried on seperate pins. THis is an issue because as I said ulimately I would like to have 2 monitors hooked to the 2 dvi-i outputs on a card. Be sure to buy a card with dual DVI outputs. |

So the quality of the anolog ouput , is a function of that produced by the quality of the card's production of analog, and not the fact there is a dvi-i connector in the way of getting it to the crt monitor via an adaptor that just gets the 4 pins correctly spaced to the crt monitor cable. But this does not mean that a graphics card with 2 dvi-i will have as high a quality analog signal as a card that has 1 dvi-i and 1 vga connector. In fact less good parts could be present on the video card for that analog signal, because they may assume it will get hooked to dvi capable lcd monitor. Also , why should one assume that a video card with 1 dvi-i ouput and 1 vga output will port as high a quality analog signal throught the dvi-i output terminal versus the vidoe card's vga output terminal. Thoughts? Anyone test this? Bu |

You're putting far too much thought into this ! As long as you buy a decent branded card (Gigabyte, MSI, ASUS etc. etc.) then the analogue output will be just fine. |

Nvidia normally have two RamDAC [channel]. First channel - VGA 2nd channel - DVI Let assumed you have two Digital Monitor. Signal Degrade VGA [anolog] port will need to convert from VGA card - Digital Anolog Anolog Digitl monitor No signal degrade DVI [digital] port. There no conversion. VGA card - Digital Digital Monitor. Do you get the general idea? It better to have straight DVI without any conversion. So, if your monitor is digital and have DVI port, use it. CapFusion,.... |

Wonder who makes excellent vga signal in a dual dvi-i ouput card at a 200-250 dollar price point? Matrox has excellent analog signal quality, however they also have no DirectX acceleration to speak of. In your price range you're going to have to make tradeoffs. -- --John Reply to jclarke at ae tee tee global dot net (was jclarke at eye bee em dot net) |

Thanks, yes I understand that. That is why I want 2 dvi-i outputs so I can eventually hook 2 dvi capable lcd monitor to the card. But right now I still have a good CRT monitor. So I want a card that has dual dvi-i ouputs but also transmits a very excellent vga signal throught the 4 exttra pins that a dvi-i ouput contains for that purpose. Who makes excellent analog vga signal on a dual dvi-i card? |
