Hi,

I've been running 2 cards, both VGA, to one CRT and 1 TFT. I'm ditching my CRT, replacing it with another TFT and would like to have just one graphics card that can "power" both TFTs via DVI.

Can anyone recommend a model?

Thanks

Matrox makes a few. There's a PNY Quadro card and an ASUS card if you like NVidia cards. There are also some 3DLabs Oxygen cards. I don't know if there are any ATI based cards.

I don't know which cards are better, though I do like my PNY GeForce4 Ti4200 card, which has dual VGA outs (though only one of the outputs supports DVI).

Of course, it also depends on your budget, and what applications you plan to use with the the card. I mostly use 2D apps, so I don't know much about 3D performance issues.

Okay, so there is an ATI Dual-DVI card, the ATI FIRE GL X1. And, MSI also makes an NVidia based card.

Also NewEgg sells a pretty cool looking card -

ASUS V9520 Video Suite GeForce FX5200 Video Card w/ DUAL DVI VIVO and Video Editing Software

I have found a very reasonable dual DVI solution. The ASUS 9180 Video Suite is a dual DVI Geforce 4 MX 440 card with breakout SVideo/RCA in and out. Mine was less than $150. I used to be a big ATI fan, but my Radeon 8500 never performed well in Windows XP for me. The ASUS 9180 has been great. You can rotate monitors and also span the desktop.

Check out the Gainward Ultra 750 based on the nVidia GeForce4 Ti4600 chipset. Googlegear carries it for $236.00 including 2nd day shipping. It is based on an AGP form factor, has Dual-DVI as well as Video In/ Video Out (VIVO).

I have been using this card for almost a year and have has excellent results with it. You can do a search on Google for the card and read quite a few reviews. All that I have read have been very positive. You can also search the hardware section of this site for others who use this card.

Hope this helps!

Barton:

Wouldn't the $130 card I linked to be above be better? It has all the same features, including VIVO, but uses the newer NVidia FX5200 chipset. It also uses 400.MHz RAMDAC's instead of 350.MHz. Is there something obvious I am missing? (Probably)

Eric,

YOu make a valid point. I saw your previous post, but all I saw was the "Fire GL" and with it's price, the Gainward is a better way to go is money is an object.

I am defintely going to have to do some more reading on this card. It looks VERY INTERESTING!
Barton   2003-07-09 02:32
Eric,

Did some more research on the ASUS V9180 card. While the $113 price tage looks enticing, the fact that the card is based in the MX440 chipset and has only 64MB of RAM severely limits the performance of the card. The Gainward that I am running, while somewhat more expensive, is based on the Ti4600 chipset and has 128MB of RAM.

If doing anytype of surround gaming, I think the ASUS would be hard pressed to keep up with the demand. I am still going to buy one to have as a backup card. If my Gainward went down, I would be in serious trouble.

Later...

I never mentioned the ASUS V9180 card. I mentioned the ASUS V9520 Video card, which is based on the new FX5200 chipset. Please let us know what you find out about the ASUS V9520 Video card.

Eric,

My bad. You did mention the V9520. This is weird. Newegg is selling both the V9520 and the V9180 for $113.99! Why would anyone buy the 64MB MX440 when, for the same price, they could have the 128MB FX5200.

I'm glad you pointed that out! I'll be sure to get the V9520 as the backup!

Thanks for keeping me straight!

Does anyone know the max DVI resolution for the V9520 card? http://www.asus.com/products/vga/v9520vs/overview.htm sasys max resolution is 2048x1536, but doesn't specifically say DVI output is possible at that resolution; I know it's not atypical for a card to support a higher resolution for VGA than for DVI.

Ben,

Believe it or not, 2048X1536 is the max resolution for a single monitor in DVI. I found it hard to believe as well, but go here.

I made a screen capture of every resolution setting available for the VS9520. There 56 images in one .zip file. This should provide the answer you're looking for.

I'm not too sure what the max dvi resolution for the v9520 is, but if it's like most nvidia cards, it should be using a silicon image tmds transmitter which will give you 1920x1200 resolution. For more information on dvi and max resolutions, check out http://www.edgereview.com/ataglance.cfm?category=Video&ID=130.



Lots of useful information there. I'm currently using a Radeon 9800Pro (the only radeon so far that i've been able to run this monitor with) with the Samsung 240t at 1920x1200 51.7Hz (or so) refresh rate, though there are still occasional dvi signal dropouts depending on the colors being displayed. Hope this helps.
Barton   2003-08-25 09:16
Well...lets try saying this another way.

The VS9520 supports a max resolution of 2048x1536 to a single monitor, not that any monitor can support that resolution to begin with. The highest I can find is 1920x1200 native.

I hooked mine up today to a Sony SDM-P232 (which has a native resolution of 1920x1200) and it worked just fine at all color settings and all refresh rates (though I don't believe refresh rates have any effect on a digital monitor).

In my post above, I make reference to a link where I have a zip file. I captured all "56" screens showing all display settings supported by the VS9520. Image 20,39 and 56 show the max resolution for each color depth.

The only problem I have with the card is that my 3-18" monitors have an effective desktop of 3840x1024. Nothing yet supports this resolution in an AGP bus in a digital mode. Colorgraphic is releasing their Xentera GT4 AGP card in October which is supposed to offer this support. We'll see what happens. I've got my money ready!

If i uncheck the box in the display properties that says 'hide modes that this monitor cannot display', then the radeon 9800pro/240t combo can supposedly go up to 2048x1536 @ 85Hz.

But that's impossible. The DVI spec only allows for 1600x1200 at 60hz. to get 1920x1200, a lower timing has to be used so that the vertical blanking can be reclaimed. I'm not too sure what the technical details are, but there just simply isn't enough bandwidth in a single link dvi to run 1920x1200 @ 60hz (and windows control panel will lie about it's refresh rate, depending on what the video card drivers report back). dual-link dvi's don't have that problem though - they can drive resolutions up to 2048x1536 @ 60Hz i think. maybe the Sony SDM-P232 monitors are dual link dvi displays? I have not used those monitors so i'm not too sure what they're capable of.

here's a press release on silicon image's latest tmds transmitter, which finally alleviates the bandwidth issue in single link dvi's http://www.siliconimage.com/press/06_18_03.asp

I just recently bought an ASUS V9520 GeForce FX5200 card, its great. A point to note is that the FX5200, though newer than the Ti4600, is MUCH SLOWER with 3D and therefore cheaper. It is the lowest-end GeForce FX card, whereas the Ti4600 was the highest-end of the GeForce 4 series.

The FX5200 is sorta comparable with a GF4 MX chipset. And speedwise isn't that much faster. But it can still play games fairly well and was quite cheap when I bought it ($150 Canadian). VIVO is also another nice feature.
