RE: Three Monitor Options for Optiplex 780?

Its not 1 DVI out. it has a DMS59 which is Dual DVI-A

DMS 59 has 59 pins its not DVI.

Each DVI -A can support 1 Digital DVI and 1 Analog VGA via the Dell X2026 cable.  These cables are incorrectly labeled as splitters as are the dms59 cables.  They are not splitters no such thing as passive splitter cable that gives you 2 seperate monitors. 2 X 2 = 4

RE: Three Monitor Options for Optiplex 780?

Can you tell me do you have an optiplex 780 also?

I can easily find a card for pci-ebut I have a hard time finding the other card you mention?

which card do you have (the PCI card)

Can you tell me where I can find an affordable one so I too can have 4 monitor setup?

Aren't the PCI only cards very rare and hard to find now ?

Thanks

RE: Three Monitor Options for Optiplex 780?

Dell Specific  PCO-E X16 Low Profile DMS 59 to Dual DVI-A cards are not rare.

They Use cable H9361  DMS 59 TO DUAL DVI  You then add the other  X2026 cable to split one of the DVI-A into DVI -D AND VGA.

You need Low profile Dual DVI -A and 2 Dell X2026 Cables

The card below comes with the dual dvi and the x2026 is linked below that.

I have no other comments this is my final post on the matter.

There are more expensive cards that do the same thing.

RE: Three Monitor Options for Optiplex 780?

Thanks for the clarification.  But I only see one DMS-59 on the card giving you dual monitor support, so to have 4 monitors you'd need 2 of these cards installed right?

I only have one PCI-e slot on the optiplex 780.  Forgive me, but I still don't understand how I could get 4 monitors from only one of these cards? 

Please clarify.

Thanks

RE: Three Monitor Options for Optiplex 780?

You are not looking at the whole picture.   DMS 59 to Dual DVI has 2 outputs.  Each DVI output is DUAL LINK meaning it has a DVI-D and DVI-A so it can do 1 digital monitor and 1 VGA monitor with the 2nd Dell cable.     If you use 2 of the cables with 2 DVI-A outputs you get 4 monitors.

The other more expensive card that I linked has 4 DVI connections.


Does not appear that you are looking at the links however making me wonder if you are just a bot posting endless questions.

RE: Three Monitor Options for Optiplex 780?

Hi Speedstep,

Thank you for your clarification.  I really appreciate it. I'm sorry but rather than buying it, I just wanted to make sure it actually supported 4 monitors, but your last posts completely clarified how it did that for me.

I can assure you I am not a bot, just a little slow on this one.  Forgive me.

1 last question: If my monitors are all VGA, can I just add simple DVI to VGA adapter for those connections so all 4 have monitors will work.  Or do I have to have 2 VGA monitors and 2 monitors with DVI input.  

My logic tells me the simple DVI to VGA adapters will work, but I just wanted to double check with you if both the Quadro NVS 420 would work with 4 DVI to VGA adapters and if the other card would work for the 2 DVI connections.

Also it looks like the more expensive card is cheaper overall.  $68.99 and incluedes the 4HDCI to 4 DVI adapter.  The other one is $48 with shipping + 2 cables  17x2 = $34 total $82.

Thanks you for all your detailed help. It's much appreciated.

RE: Three Monitor Options for Optiplex 780?

DVI -A Dual Link can feed 1 VGA and 1 DVI-D (DIGITAL Only) with the X2026 cable.  You cannot convert DVI-D to vga DVI Dual Link has 1 vga 1 DVI not 2 vga or 2 DVI.

The 4 DVI card CAN NEVER DO ANY VGA because its DIGITAL ONLY aka 4 x  DVI-D.  DVI-D is missing 5 pins for Analog Red Green Blue Sync and ground.  DVI to VGA cables need DVI-A /DVI-I

RE: Three Monitor Options for Optiplex 780?

Just to clarify information here, Dual Link DVI refers to the possible resolutions and refresh rates supported, up to 2560x1600 @ 60Hz, or 120Hz at 1920x1200for Dual Link.  24 bit colour modes and 165MHz pixel clocks must use Dual Link as welll.  

Having both digital and analog signals in the same cable refers to DVI-I.
