Think McFly......think! That's like asking why anyone would want a dual (crt) monitor setup. LCD's take up less space, use less power, have (near) perfect geometry, and are easier on your eyes. While dual setups aren't for everyone, extending your desktop across two monitors is the perfect solution for those who need to get more work done in less time.

lol well i just meant the two screens in general not the why lcd over crt. Im with the LCD crowd as of a few months ago :)

Try using Autocad or 3DSmax or Adobe Premiere on just one screen with a large project then get back to me :)

so how does windows not support 120dpi? have you ever heard of largefonts?
well I use 120dpi with my 21" monitors, 1920x1440.
My CRTs have DVI-A, which I've been told there is no difference from DVI-A and VGA.. so I never bothered to try it, as I have to pay $20 for the cable.

somewhat important. next card will definately have it though due to it being readily available. right now I'm surviving with 2 video cards.

But dual DVI-I would be nice for the future when I finally go LCD. It 100% gets my vote!

Except for the fact that Parhelia only throws out Triplehead in DVI+2RGB mode. ;) Two of those LCDs are running off analog signal.

There's only a few select cards that can throw out more than two DVI signals, and none of them have any measure of 3D muscle. There's the Matrox cards (G200MMX/G450MMS), the Quadro NVS 400 PCI, the AppianX (Radeon VE) - and the stupidly expensive Colorgraphics Xentera GT series, packing multiple Radeon 9000 processors. Pinnacle of that would be the Xentera GT8 PCI, pushing eight ( :Q ) DVI displays.

Geforce 6800U does as well

also the Fire GL 256 xt (?)

its like a radeon 9800xt with dual dvi output and geared toward 3d apps rather than games,.

More than two DVI signals, folks. Dual DVI + performance is not hard to find these days - all you have to do is say the magic words "Quadro" or "FireGL" ;)

No need. You can always use an adapter if you need analog.

Time to stop the bullsh!t (A fairly complete list of Dual-DVI cards)

> until CRT's use DVI......
As I understand it, some high-end CRTs have DVI ports. I'm thinking in the 22" range, tho.

> because some times I need analog to configure Linux
I've had no problem getting Gentoo running on my Ti4600 Dual-DVI card (currently with the new X.org release). I had KNOPPIX running fine before I went all-SATA. Admittedly, I've only seen Mandrake (maybe, 9.x) try to configure XFree86 both displays out-of-the-box.

> Dual DVI is almost impossible to find right now.
This really saddens me, Kris. Please refer to the link above.

Aside from the recent announcement of the 6800 GPU, we really haven't seen dual-DVI offered with *current* consumer graphics chip leader (Radeon 9800/FX 59x0). I hope this is the start of a trend. LCDs aren't in the same league as CRTs when it comes to response time. As with anything, the technology will eventually arrive. And when it does, it'll be cheaper to boot. Besides, even those of us who already have two LCDs are just a hot deal away from all of the goodness that multiple 2001FPs have to offer.

CRT's using DVI would be a completly stupid thing, it'd have to be sent as digital, and the monitor would have to change it back to analog to be displayed on the crt monitor.

no it wouldn't.. all CRTs using DVI now uses DVI-A.. which is DVI that carries the analog signal.

But isn't that analog signal coing out of the DVI-A connector at best the same quality as the analog signal coming out of a 15-pin dsub, since most dual head cards use a pair of identical RAMDACs for output? And if what Eug says is true, you might actually wind up with a WORSE signal than you get out of the dsub connector because some of the manufacturers are skimping on the DVI-A output quality because they figure that the dual-DVI market is only concerned with the DVI-D performance.

I bought the 5950 without it, but was unhappy with it not being there. If same gpu type has it, vs a same gpu card without it is a buy decision for the card with dual dvi. I don't think all 6800 ultras will have dual dvi but I'll only buy ones that do. I have for the last year or so wished that cards came out entirely with dual dvi, since in many cases its easy enough to add a dongle if you want dvi/vga.

Oh well - high time or rather past time vendors should be giving us this. The next thing is to be sure, and I think we do @ 256mb, have enough memory to comfortably run apps on both screens at high res.

the people that want VGA, are they all forgetting pretty much EVERY graphics card that comes with DVI also has VGA? the DVI-I standard no only includes the ability to run two displays,but it also has RGB output(hence, the DVI to VGA converters). so a dual DVI card can handle 1/2/3/4 DVI or 1-2 CRT. dual DVI is the way to go.
