Here's my question:

Im in the process of building my new setup (waiting for the case/PSU to get in from newegg :(), but was curious about one thing on my ATi AIW X1900. Right now Im using a Dell 2007FP, but what happens when I go to add another LCD screen? I ask this because the X1900 AIW has 1 DVI output, and 1 VGA output. Is there a way to convert that VGA out to a DVI out?


Thank you in advance
 
no, you cannot go from vga to dvi, just like you can't convert standard def. to high def. you can only go from higher quality to lower quality, not the other way around. you can get a dvi splitter for what you need.

What the hell are you smoking? VGA is capable of the same resolutions DVI is, it is only shunned for use in digital monitors because using it requires a digital to analog, then back to digital conversion.

Most LCDs come with both a DVI-D and VGA, or a DVI-I input which can accept both digital and analog, SO YOU DON'T NEED A CONVERTER. If you use the VGA or DVI-I to input an analog signal, the monitor will convert it to digital for you.

FOR INSTANCE:

Your Dell 2007FP has both a DVI-D and VGA input, and you can use either one. Thus, if you had TWO Dell 2007FPs, you could hook one up via VGA, and the other via DVI.
 
get an LCD that supports both DVI and VGA inputs. Then you needn't worry about it.
A DVI splitter won't do him any good unless he wants the same shit on 2 screens, and most people with dual monitor setups don't run like that.
 
edit: oh snap, didnt realize it had both VGA and DVI inputs....shame on me :(

ah, ok thanks...Will that act like a 2nd extended output though if I use a splitter? Sorry for all the questions

I'm not annoyed at the questions, I'm annoyed at the retard who gave you completely incorrect information.

If you get a DVI splitter, this will clone the image from one video output on multiple monitors. Some people like this for say, giving a presentation or something, but it will not increase your desktop size.

If you want to extend your desktop with another monitor, use the VGA output for the second LCD monitor. You'd be surprised how well modern LCDs work with VGA inputs, they've gotten SURPRISINGLY good.
 
Question I have is, I've got the Dell 2007wfp (wide screen) monitor which has the native 1680x1050 resolution. Just found out that my Nvidia Geforce FX 5200 ultra video card won't support it (even with the newest drivers, it'll support a max resolution of 1600x1200). :(

My monitor supports DVI-D, so does that mean I have to find a video card that only supports DVI-D, or would a DVI-I video card work as well?

Yes, the maximum advertised DVI resolution of the FX series is only 1600x1200 (within spec), but you can try 3rd-party monitor utilities (Like Powerstrip) to see if you can force the card to sync at 1680x1050. The monitor may be able to sync at less than 60 Hz, in which case you can run it at the higher resolution.

Your only other alternative (aside from a new video card) would be use the VGA input.
 
I have an Apple Cinema Display, 23". It only has DVI input... so I'm SOL if I wanna somehow hook it up to my thinkpad, which only has a VGA output, right?

Try knowing what your talking about before spreading FUD!

I think Apple 30" requiresthe Dual-Link DVI port (DVI-D), like dell's 30" - but i am not sure about their 23", just check the specs on apples site.

the 23 and 20" dont require Dual Link DVI

No, you see, DVI-VGA adapters work like this:
your graphics chip has a DVI port. Your monitor connects through VGA. Hence the DVI-VGA adapter. It is not backwards-compatible.

What I need is the inverse: my graphics card has a VGA port. My display connects only through DVI. Is there a VGA-DVI adapter in existance?

Geez, people need to just take a moment and think before they assume they're smarter than everyone else?

I know of a way to go from lower quality to higher quality. All you need to do is buy a more expensive, and better product than what you already have :p
 
What if you wanted to hook up three monitors? You'd probably need a second video card or a splitter that didn't just clone the main display, but actually extend the desktop, correct?

This is the only "splitter" I know of that would do that: http://www.matrox.com/graphics/offhome/th2go/home.cfm

Otherwise, you would need another video card. An exception would be if you had a Matrox Parhelia or similar.
