Graphics card wanted to run 4 monitors off Dell PC using PCIe slot for power

I have a Dell Monitor P4317Q 43" UHD 4K Multi - Client monitor but my current graphics card can only muster 2 or 3 screens.

I know I could daisy chain a display port but that hardware is sometime flaky so I'm looking at a new graphics card which can offer 4 screen output but which only draw power from the PCIe slot rather than linking to the power supply, which is not easy with Dell.

Thanks
 
4x 4k screens or something else?

What do they display, just 2d stuff?

What machine will the graphic card be going in? Does it have onboard graphics that could possibly be used for 1 or 2 screens?


Something like a FirePro or Quadro will do 4 screens via displayports but is likely underpowered for anything other than 2D/Office work

The machines are originally Xeon serves from Dell which are running Windows 10 and around 16GB RAM. I got them way cheaper than any spec of PC and they are absolutely rock solid and fine.

However, the Dell PSU is proprietary and you can't easily swap it out (no need really) or add any power from the PSU or from the MB so you are left with putting something like a 750ti card in and using the PCIe power. I can run 2 or 3 from this 750ti in there now but I would prefer to use something onboard to handle all 4 outputs for the Dell Monitor P4317Q which can split into 4 1080 screens on the one monitor.

I came across this PNY NVIDIA Pascal QUADRO P600 2GB GPU with 4x DisplayPort Adapters (https://www.**********/products/2gb...28bit-64gb-s-1195-tflops-singlep-4x-mdp-14-s?) which made me think I could perhaps do it from the GPU rather than using one of theese3 (3 or 4 port) https://www.startech.com/uk/AV/Disp...-DisplayPort-Multi-Monitor-MST-Hub~MSTDP123DP
 
I'm a little confused - is it important to treat it as 4 screens rather than one big one?

Cards mentioned above will do it, I believe there is also an HD7750 that can do it but it's not great value as that's quite an old card now. Alternatively could you fit two basic cards for two outputs each?

Click to expand...

The Dell Monitor P4317Q 43" UHD 4K Multi - Client monitor can run 1, 2, 3 or 4 screens but want it to run 4 with 4 x inputs. I can get 3 from my current GPU (750ti) and I "guess" I could run another 2 from another GPU but I can recycle the 750ti elsewhere so a new GPU "seems" the order of the day.

Or is a 4 way display port splitter the better option ?
 
Drawing power is easy if you take a feed off a 4pin molex connector that powers an optical drive or large HDd .... there are normally spare connectors in dell machines for more drives.

Still not really understanding the setup you want though. Are you wanting 1 machine with 1 gpu that has 4 outputs. Then you’ll take each output and run it into a single input on the monitor. So 4 cables from the card to the display ?

The display will then think that it’s 4 separate inputs ?

In Windows your display setup will want to combine those desktops of each output into a single space you can move your mouse between. ... so you’ll still end up with a single desktop space spanned across the outputs.

Surely you would be better running a single 4K desktop? Via a card that output 4K and using a single cable from the card to the display ?
 
Sorry, this display is unique, it has 4 inputs. It is primarily used for trading with 4 screens in the one 43 inch display.

It can act as a single monitor, 2 monitors, 3 or 4. - up to you.

So 4 outputs from the GPU into 4 inputs on the monitor or alternatively, 1 display port output into a splitter or daisy chain seems the order of the day from my layman's point of view.

The GPU option moves this splitter or daisy chain off the desk, that's all.

Not sure there are any molex connections - can't get at it right now - I am sure only SATA.

Model is a Dell Poweredge T20 which looks like this inside https://i.imgur.com/imrdNky.jpg
 
Will the T20 allow you to use the onboard graphics as well as the discrete video card?

If you aren't doing anything too taxing there's potentially two DisplayPort and a VGA going spare.
 
That's not unique, there are other monitors that can take 4 inputs and assemble one image. We're asking why you need to do that rather than use one large 4k desktop and manage layout yourself.

Is it because the trading software prefers to be run full-screen?
 
As above. You can run a single desktop utilising the whole 4k display via 1 single DP cable from a single card.

I just dont understand the need for 4 cables from a single card to the same display. Yes, that is technically possible, but it seems an awkward means of getting a 4k desktop space when 1 cable will do the job.
