1600x1200 via DVI on Nvidia cards?

[gel]

Hi,
I'm gonna sell my CRT display to buy a new TFT 20.1" with a native resolution of 1600x1200 pixels and a DVI input.

My current video adapter is an MSI StarForce GeForce3 Ti200 64mb DDR. This video card has a VGA analog output and a DVI digital output.

Can I use 1600x1200 in digital mode (DVI) with this card?

What are the other Nvidia-based cards (including Quadro models) that can output 1600x1200 via DVI ?

You should be able to with that card without any problem. Any modern nVidia card with at least 64meg of VRAM should have no problem doing that.

Should, yes, could... doubtful.

The resolution and color depth in relation to the amount of memory isn't an issue, but the DVI output of 1600x1200 is. Most of the cards do not support resolutions higher than 1280x1024 on the DVI output while they support upto 2048x1536 on the analog output. This has been a considerable problem for the 19" and higher TFT's that do handle 1600x1200 and higher.

When these TFT's were appearing we bought into a whole stack of them and discovered that most of the cards didn't support the 1600x1200 DVI. We had only a few cards that did, mongst which the WildCat 51xx and 61xx series and the FireGL's. The only Geforce 3 TI500 cards that support 1600x1200 DVI were those made by Guillemot/Hercules (which used the 1600x1200 DVI output as a specific marketing feature). Unfortunately these cards didn't see the light of day for too long because a few weeks after we replaced a load of cards with those they were suddenly unavailable and no longer being manufactured.

It really pays to make 100% sure that a card supports 1600x1200 DVI before jumping into TFT's (either that or discovering you're also in need of a new card, which would be an unexpected expense). I'm no hardware engineer but from what I understand, resolutions higher than 1280x1024 DVI require two clock chips on the board since it's not a common function for most GeForce based cards.

I had no idea. Thank you for the clarification.

Hi everyone, 1st post for me =0)

On my home workstation I have a GForce4 ti4600 from Leadtek, running as a Quadro4 900XGL, with two NEC 22" monitors. The card has the usual Dsub and DVI connectors which I am utilizing with DVI to Dsub cables (and Dsub to DVI).

I'm having no trouble running both monitors at 1600x1200 @ 85hz.

BUT when it comes to running Maya, I can only use the second monitor for a few things like the outliner window. The main issue is that particular windows like any viewport or hypershade or hypergraph window will not update/refresh in the second monitor. This is a major pain that I would L O V E to fix.

I'm beginning to wonder if I should start looking at expensive DCC cards on the market (say it ain't so!).

One thing to note, is that on my business workstation, we've got an actual Quadro4 750XGL running dual displays and the SAME problem occurs there.

Any and all insight is much appreciated, thank you!

Easy enough to fix; disable dual view and enable nview.
win2k's dual view mode doesn't support openGL on the 2nd head; where as nvidia's nview mode does.
Also the gf4 series cards updated the transmitter for the DVI; so it can support beyond 1280x1024.
pre gf4 cards only do 1280x1024.

1000101,

I've now done what you suggested (dualview off, nView on).

It appears that dualview now thinks that the first monitor is double wide now, and the second monitor is greyed-out since I'm not using dualview's "Extend my Windows desktop onto this monitor" funciotn (this essentially means dualview is off, correct?).

Main problem now is that Maya gives me a Fatal Error everytime it is launched (saves my untitled scene to a temp file too).

I'm hoping that there's a nView setting somewhere that will get Maya running. I've tried creating a dcc (or Content Creation) nView desktop with Maya added to the "Applications using custom nView settings:" window.

What am I missing??

Note: running WinXp Pro
Note: using Detnonator dirver 41.09

Thanks, I'm ALMOST there, I can smell it!

OK... I figured it out. I'm running RivaTuner V2.0 RC12 and in the Professional tab I enabled overlays.

Disabeling that sucker made everything work wonderfully.

Now I feel all warm and fuzzy - like a peachy peach.
WoHOOO!!

BTW, thank you 1000101

anytime sir

I had the exact opposite problem.

I was running XP Pro and I have a Quadro 4 700 XGL. I couldn't run both of my 19" monitors full accelerated. Only the monitor I chose as the main monitor would work accelerated. That was using nVidia's nView. In 2k Pro there is the option to enable Dual View.. or.. treat each output as an independant video card. That was the only way I could get both monitors to run independantly accelerated. Each desktop is running 1600x1200x32 @ 75Hz.

A good way to check (if you don't have Maya) is to download the bubble demo from nVidia. Start it up on one monitor, then move it to the other. In XP it would just stop moving all together. In 2k it worked fine on both monitors.

If you can get both to work in XP, then darn. I already formatted (and I'm not formatting again for a while ). But I could only ever get it to work in 2000.

With 41.09 nVidia driver on XP

Diplay properties >> Settings TAB >> Advanced BTN >> GeForceXXXX TAB >> Open GL settings SIDEPANEL >> Multidislay Hardware Acceleration set to Multi-Device Performance Mode

Results are OpenGL on both monitors without nView. I dont like the fact the nview makes windows think that its a one big monitor and maximizing windows on one monitor is not as easy as it should be.

I'm sure it works...
that's because you're not using the DVI digitally.
Your card has a DVI-I which means that if you connect that output via a DVI-I -> D-sub connector you're still in analog city. If you had a DVI-D you could only connect it to a digital flat panel display. DVI-I is a connector specifically made for a smooth transition from CRTs (or analog TFTs) to digital TFT displays.

For example, the same thing happens if you connect your DVI-I to a DVI-A input (some diamondtron-based CRTs have that connector). The display gets 1600x1200 (and over) but in analog mode.

Anyway, that's not what I meant. No CRTs, 'cause I'm gonna sell mine... and no analog stuff anymore (dsub, dvi-a or whatever)

ciao!
