Not Detecting a Seventh Monitor (Workstation)

[EvelynX]

Calling all monitor junkies!

Sometimes our jobs demand maximum productivity, and to achieve that, we simply demand more screen real estate! In no profession is this more apparent that in the ever expanding industry of CCTV operation. I am the one who watches! But unfortunately, I can't watch all of you... Yet. Just kidding, I monitor private sites so no Illuminati.
My problem is this, My good friend Windows, is detecting no more than six displays.
As it stands, I am nearly maxed out and require the use of a few extra displays, which are already set up. Unfortunately, upon plugging them in, I find that neither of them are being detected.

TIME FOR A BIG LIST
What exactly I am trying to do;
I am attempting, but unable to connect at least one the three remaining bottom row monitors to one of the three remaining DVI-D Dual Link out ports on the video cards.

What is happening;
Neither the display, nor Windows are acknowledging each-other.

Screens:
Top Row, 3x Panasonic TH65PB1 @1080p
Bottom Row, 6x LG Flatron E2242 @800p Deliberately.

 

Hardware: (Rather sad)

CPU: i5 760 @2.8Ghz
GPU: 3x Asus AMD Radeon HD5450 @650mhz 2gbGDDR3 (Possibly where my problem lies)

RAM: 16gb Crucial @667Mhz
MB: Asrock P55 Deluxe It has no display out.

Software:

OS: 64bit Windows 7 Professional SP1
Drivers: Latest appropriate drivers for all hardware.

Display output notes:
The 3 top row monitors are connected via HDMI, one per graphics card. (Successfully)
3 of the 6 bottom row monitors are connected via VGA, one per graphics card. (Successfully)
3 DVI-D Dual link outputs remain unused.
Seventh display is unsuccessfully connected via DVI-D Single link cable through a DVI-I Dual link to VGA adapter. (Possibly where my problem lies)

So are there any monitor junkies out there who maybe able to help me out?
Are the cards capped out at 2 displays despite having three available ports?
Have I made a herp derp with my VGA adapter?
By default, does windows cap at 6 monitors? (I don't believe so.)
Is a hardware upgrade entirely necessary for the additional monitors?

I hope you folks can help me out, by the way things are going, it looks like that by 2016 I'll have another row of six monitors, by then there will be specialist hardware but for now my not Illuminati bosses would like to keep everything on one computer.

9 squirrels at once on camera 5 today. Everything is going as planned. that Binary (sorry almost random post)

I have 1 5450 and it can't even handle 1 1080p monitor running a youtube video, I use 720p

[CoolaxGaming]

Ok NVIDIA caps at 3 monitors and AMD at 6.

Even if you have a 100 graphic cards, you still have a cap of 6 monitors.

How odd,  in my instance they each effortlessly handle 2x 1080p  only averaging 19% load each.

It can be noted that they are only used to drive resource light applications and never used for anything otherwise.

I just tried to load a YoutTube video to test and the whole system crashed.  :angry: No more of that!

Even if you have a 100 graphic cards, you still have a cap of 6 monitors.

I was under the understanding that there is no limit to the number of monitors, and that the 6 monitor cap on AMD applied only to Eyefinity, not to random monitor usage.

Do you know of a workaround, or piece of software that will allow me to utilise the additional monitors?

It should be noted that there are no full-screen programs being used. All windowed.

Source? i'm pretty sure that NVIDIA cap is only for NVIDIA Surround. JayzTwoCents has 4. 3 in surround and 1 auxiliary

No impossible.

Sorry, the last NVIDIA card I used was a gt 630. Now it seems that the cap is 4

[EvelynX]

No impossible.

Could you provide me with some source to present the findings?

There are a few instances similar to mine around the internet and several suggest that it is only Eyefinity that is capped at 6.

The fact that I will be utilising each display as an individual, should change the situation. Again, I'm not gaming at all. Just using individual displays.

It's a shame that in the instances mentioning 9 or 12 display video walls do not specifically list hardware or construction.   :wacko:

OK. 

AMD consumer grade has a max of 6 in surround

Nvidia consumer grade has a max of 3 in surround and an extra 1.

 

AMD Firepro has support for 6+ monitors

Nvidia Quadro 6000 has support for 9+ monitors.

[EvelynX]

Exceptional! Probably what my issue is if that is indeed the case. So we probably have a hardware limitation!
My not Illuminati overlords want this pushing for without a hardware change but if indeed the only way is certainly something to look at.

No way they will pay for a 6000 series Quadro or anything even close to that so if you are right, It looks like the monitors will end up being spread across 2 different computers.  :mellow:

[thorpj]

 

Could you virtually split each display into two? so you could have 12 cameras viewed?

Each screen can display 1 to 64 cameras within software, I could run all these cameras + more on 3 displays but the more I have to one screen, the less visibility I have, considering each camera view will be smaller. I need to be able to effortlessly spot movement and at a certain point, a camera preview is too small to notice anything outside of focused vision.

Hence why getting the maximum screen real estate is so important. In this instance, high resolutions are actually a hindrance.

I need raw size, and to get that, the most efficient thing I can do is attach as many screens as possible.

Does anyone know of any hard/soft-mods that would allow me to force more than the 6 displays capped on consumer grade products?

[TDP_Equinox]

Sorry, the last NVIDIA card I used was a gt 630. Now it seems that the cap is 4

STOP. 

You can plug as many monitors into the graphics card as it supports. 

The cards i am running now once were in a machine that was connected to 12 monitors at once (displayport splitters). 

OP, What cables are you using to connect all the screens?

[CoolaxGaming]

You really don't know anything about displays.....

OP says his company cannot pay for a quadro or FirePro.

AMD cards have a max of 6 monitors. You have 1 gpu still 6 monitors. 2 monitors also only 6 monitors.

NVIDIA cards have a max of 6 in SLI. http://www.nvidia.in/object/sli-technology-multimonitor-in.html

@TDP_Equinox

in nvidia surround or eyefinity yes there is a limit. 

But you can, and i have, hook many more displays up to a graphics card. 

look at this 

The specs :

1 PC

1 AMD Phenom™ X4 CPU

4 ATI Radeon™ HD 5870 Eyefinity 6 Edition Video Card

24 1920x1200 Dell 2408WFP Display Port Monitors

This is beginning to look like all the other threads on the internet with the same problem.
Some sides saying it can't be done, the other side showing clear evidence it can be done, but with no means in which to actually do it.

As I said in OP, I have three cards each with 3 display out ports, all functional, but no matter what the combination, I can only get six monitors running. (3hdmi, 3DVI-I, 3vga)

I just wish I knew what exactly these folks where doing to get more monitors running. :'(
By the looks of it, we're probably going to have to buy a new computer. Perhaps I can download that software in which two computers are run seamlessly as if one, at least with the keyboard and mouse anyway.

I like a clean desk.

If you had all displayport monitors, you could get this going in five minutes. I don't know if there is a way to do it with mixed connectors.
