OT: Video card to drive dual LCDs

farss wrote on 1/18/2004, 4:30 AM
So far the only video card that I can find with dual DVI outs is the Matrox Parhelia. I know the Matrox boards are the best for image quality but it's not going to improve the rendered image and at around AUD 1,000 it's kind of expensive given that most of it's smarts are of no use to Vegas (well as yet anyway). Also I did note that Matrx mention that when running dual head the two displays are seen by Windoz as two desktops not one extended one.

So two questions:
1) Anyone running a Parhelia with Vegas, if so how does it cope with tow desktops versus one extended (that's the way I'm running at the moment)?
2) Anyone know of another video card that does dual DVI?

Hi Fars,

Ive seen some cards from ASUS (9600radeo chip) that have DVI and VGA outputs thats could be used simlutaneously.

cheers

There is an ASUS card that I was prompted to that has the nvidia GF5 series onboard. It says it has dual DVI on it, but to be thorough, the picture shows DVI and plain old VGA on it, so I'm not sure.

Good news on the Matrox is that the dual head mode of 'P' series cards can be primary/secondary or primary/primary-extended. It is upto the Matrox configuration you select. This can be important for directshow overlay, but as Vegas doesn't use that for preview, I suspect either mode is of equal performance within Vegas.

P750 is a bit cheaper, and gains you AGP 8x whilst Matrox regroups for its next gen card. P750 doesn't earn the capability of WYSIWYG drivers but does provide directshow overlay to Tv-out (purevideo=32bit equivalent of DVDMax from the 'G' series). I'd hope that anything that Sony wrote (to support windows/pci-overlay aswell as compressed DV via OHCI output) wouldn't require a full Parhelia as Sony would only be serving Matrox with such a lock-in.

I'm reluctant to buy another Matrox product just now. I liked my G450 and still use it, but I can't believe that the VGA or Svideo/RGBs out of the Matrox cards is really noticably of higher quality than the nvidia/ati boards. I'd think very carefully before buying again. I feel that the USPs of Matrox are being held back by the marketing department and lack of mass market due to the poor 3d (OpenGL and some elements of DirectX) performance. I'm just not certain, at the right price I'd care a little less about this. So please bring on Matrox's next family of cards!

Check out that Asus nvidia board for that dual DVI claim. Circa US$160.

The Matrox Parhelia I purchased new was $375.00. Im driving a Viewsonic VX900 as the primary monitor and a Viewsonic VA720 as the secondary monitor, both with analog feeds. I also routed the TV output to my JVC distribution (JX-S700) to view the output when I do short renders or previews so that I can view the media player and the tv at the same time. This is not so much for colors but motion and jitter and the like. Editing is still done by the firewire to the tv. The CMOS setting of the AGP memory is set to max as Matrox states. Also running 2 gig of memory DDR 400.

Don't know about the price, but the nVidia quadroFX series seems like it has alot to offer.

Hmm,
found a few, PNY seem to make some nice dual DVI cards but they're even more overkill than the Matrox stuff.

Need to do more homework I think.

ASUS make some excellent low cost dual DVI video cards.
The 9560 VS sells for $235 Canadian here in Toronto.

I use the older version of this card to run two 19 inch
Samsung TFT 191T monitors. Works beautifully.
( The 3D speed is also better than any of the Matrox
cards if you like to do a bit of gaming for fun. )

Thanks heaps!
That's more like what I was after. Having to go through several links to check each card's detailed specs was driving me nuts.

ATI & nVidia both make dual-head cards. Gainward has both DVI and analog, or both DVI. I know that some Radeon series cards have dual head; my Radeon 9800 Pro has standard & DVI. If you searched, you could probably locate a Radeon with dual DVI.
