Clearer picture? D-Sub, DVI-D, S-Video, Composite?

[Goon]

The dvi will look the best, so if you can use that.
Here's a link that i think has what you need to convert the signal : http://www.pacificcable.com/More_Pages/DVI/DVI-Converter.html

otherwise, go with the d-sub. Modern d-sub connections don't lose too much to a digital connection, so this won't really be a step down.

As far as composite and s-video, these are video formats, and while I haven't found any information pertaining to resolution limitations which would prohibit your using them for a high-rez monitor, these input/outputs are intended for use with a television, or using your monitor as a television, and so, are most likely unsuitable.

wow... so many. I'm not quite clear how those would do it... I see lots of splitters and extenders but nothing specifically saying DVI-I to DVI-D..... which model might be able to do this?

[singularity2006]

I just read an article from Dell's website that said that DVI-I is a dual connector that supports both digital and analog signals. Also, their monitors should also support the DVI-I output. But then I asked their tech support and they said I need to buy a new video card with only DVI-D. What gives?

Based on that, I'm guessing I should try getting a splitter? I think I understand why now... but hmm.... I should check my cables. Because really, all I would need is a DVI-D only cable, right? And the video card should work fine w/ the monitor?

DVI-I includes analog as well as digital signals. A DVI-D (digital only) monitor will be perfectly capable to work with this. Only the very rare DVI-A (analog only) can not be used with a DVI-D monitor. A conversion between DVI-A (or VGA) to DVI-D is technicaly possible, but useless, since the picture quality is determined by the weakest link (the analog part) and not worht the money and effort.

I have a Sapphire Atlantis Radeon 9600 card w/ DVI-I, D-Sub, and S-Video outs. But sadly, I am unable to use a DVI because my video card outputs DVI-I and the LCD only takes DVI-D. With that said, is there a convertor from DVI-I to DVI-D? Or is it worth getting a new video card w/ DVI-D support? Or will I get better results using s-video (better as compared to D-Sub).

Try again with the dvi, it will work. Call their support if it doesnt. In the drivers you may have a checkbox titled something like "enable alternative dvi method" try that.

ooh, that did it.... nice.... thanks!

[singularity2006]

problem fixed. ^.^

[singularity2006]

On another note, is there any difference in the quality of the video signal to the monitor if I outputted through from my DVI plug to a DVI to VGA convertor to my monitor's VGA input? Or would it simply be useless?

[Srek]

Most likely the image quality will suffer due to the additional conenctors in this setup.
If you have to use an analog signal and a VGA output is directly available i would use it.

If you just mean one of those small dongles which just can the connector to a 15pin one then you *shouldnt* notice any change in the image quality.

Actually, i've noticed quite a difference in picture quality when using the DVi->VGA adaptor as opposed to using the VGA-output directly.
I have Geforce 5900-card and a Philips 202p4 monitor and the picture was much better when using the adaptor. Don't ask me why, but this could be due to the internal electronics on the graphics-card. Maybe DVI is the primary output, and the VGA is just a quick-fix to add that support?

I don't know, i only see the difference on my monitor.
Try using that adaptor and see if you notice anything.
