8560w with NVIDIA QUADRO 1000M can it drive 2 extrenal monitors??

Hello has someone tried to use a 8560w with NVIDIA 1000M or 2000M with docking station an 2 ADDITIONAL external monitors (DVI or DP)?

NVIDIA + HP + DELL are not giving this info.

In fact the older and slower NVIDIA NVS 4200M in a LENOVO T520 can drive up to 4 MONITORS using the docking station, thats official on the LENOVO web.
The 4200M is older and 50% slower then a 1000M...

I did ask HP support in Germany and the told me that only ATI/AMD support this officially. NVIDIA is not confirming this because of certification and compatibility issues with software.

 

Yes, your GPU does support two external monitors. Whether or not this feature is physically enabled by HP, I'm not sure.

 

I did find a LENOVO doc showing that the T420/T420s/T520 can drive 4 monitors, the W520 is listed "only" listed as triple...

 

Two external monitors with the laptop internal OFF. No nVidia GPU to this date can run more than two monitors at once (unless those new 6xx -series can).

That w520 runs two monitors with nVidia and one with internal Intel GPU.

 

Hello this is the info that everyone tells. But fact is that LENOVO uses the NVIDIA NVS 4200M (T410 T 420 T520) driving up to 4 Monitors the internal and 3 additional external.

Are you sure about this?? Would this not cause performance troubles? Depending what application is running on the internal GPU or the NVIDIA GPU?? And if yes are they driving on the T520 2 monitors with the internal GPU and 2 with the NVIDIA to get 4 Monitors running??

Fact is that the datasheet show that the W520 (NVIDIA QUADRO 1000M) only 3 monitors, the T410, T510 T520 with NVIDIA NVS 4200M 4 Monitors!!

How are the managing 4 on the T520?

 

I own this laptop and have tested this, the W520 will run two external monitors plus its own internal screen. In theory, with the dock, it can support four, but I have heard that users have experienced problems with this configuration.

 

So you did test this without dock... who did tell you about the problems with 4 and dock??

 

Users on this forum and Lenovo's. Google search the issue or ask users lead_org and Thors.Hammer (they're on both forums).

 

So I did some digging...

Looks like the NVS 4200M is the greatest and newest nVidia has on offer. NVIDIA NVS for Notebooks

NVS 4200M
NVS 3100M
NVS 2100M

According to the specs those can drive up to 4 monitors, older generation such as NVS 2000 are limited to two and that's what most of the laptops are still equipped with.

If you really need three monitors, either choose AMD or wait until those newest GPUs are available in the laptop you want.

 

I dont know if the NVS series is the NEWEST... but its sure NOT the fastest NVIDIA.
The Quadro 1000M and 2000M in the W520 have 128bit memory connection, the NVS only 64bit. So the NVS is significant slower then the 1000M!

For some reason HP and DELL don't tell if their 1000M models can drive 3 Monitors. Perhaps its deactivated in their drivers or they simply don't want to guaranty that it will work. If you ask for multi monitor support they point to the FirePro 5950.

But the W520 with is ISV certi. and can drive 3 Monitors. So we have a prove that the 1000M & 2000M can do this.
Or LENOVO has a special driver for the 1000M/2000M in the W520 that HP and Dell are not using.

Thats why I try to find someone with an HP 8560w and NVIDIA 1000M who did try this!

 

Just more advanced feature-wise, or whatever
Looking at the benchmark list here NVS 2100M and 3100M
are about as fast as the FX570M in my 8510w and that's three years old already. Clearly entry-level cards, for example someone who just needs to run spreadsheets in multiple monitors but has no need for 3D acceleration.

As explained before, it is the 2000M and Intel used together that enables w520 three monitor support. Has to be done on the hardware level, so you don't just enable it with drivers on some random brand computer

 

The link doesn't show a qualified comment from someone at LENOVO explaining what they are doing (or I missed it?).
Its hard to believe that they are doing it this way, but maybe you are right.

If they do it this way, what performance will the ISV cert. programs have if you run them on the screen that is managed by the internal video GPU?

 

More than one GPU in one computer isn't new invention. When I looked at the w520 device manager, there was two graphics cards just like a desktop would have. A simple dual card setup.

Since the 2000M can output only to two monitors at once, the only logical choise is to add another GPU if more outputs is desired. Since the performance is dependant on the GPU in use, basically you would like to run 3D in high-performance two monitors and the 2D tools / documentation on the third iGP monitor. Even if it isn't as powerful, it is still one display more than the competitors have.

 

Of cause this is a solution.

What confuses me:
With the NVS (LENOVO T520) Nvidia can use 4 displays!
Is the Intel GPU capable driving 2 displays in this set-up?
If YES why they cant do this with the W520 and the 1000M?
If NOT then the NVS must drive 3 displays.... this would mean the NVIDIA GPU can drive more then 2 screens...

Who can solve this mystery??

 

Umm...

T520 has NVS4200 that is capable to run 4 screens by all itself.
"Discrete NVIDIA® NVS 4200M (1GB VRAM ) with Optimus™ Technology"

You did

Totally different GPUs. One that can do 2 displays and another one that can do 4. Simple as that.

 

Sorry, perhaps I am stupid....

Both use Optimus...

Why do you think the 4200M can drive 4 screens alone with Optimus, and the 1000M can do only 2, and need the Sandy bridge to do third?

The data-sheet of the W520 say "As an added benefit, users of the ThinkPad W520 running Genuine Windows® 7 and NVIDIA® Optimus™ technology will
be able to run up to two external displays in addition to the W520’s
main display for a total of three displays."

 

This from the HP website:
HP EliteBook 8560w Mobile Workstation - Advanced Docking Station: Using More Than 2 Simultaneo​us Displays on Windows
Information
HP EliteBook 8560w Mobile Workstation - Advanced docking station: using more than 2 simultaneous displays.
Details
Situation :
HP EliteBook 8560w laptop is plugged on an advanced docking station (120 W). From there it is connected to two other external monitors and this was not working.
Following are the results when DP2DVI Active DisplayPort adapter is used:

- Internal monitor + DVI external monitor on DP2DVI Active DisplayPort adapter + VGA external monitor directly on the VGA output of the docking station: OK.
- Internal monitor + DVI external monitor directly on the DVI output of the docking station + VGA external monitor on DP2VGA Passive DisplayPort adapter: OK.
Hereunder are the results of tests when using both DP adapters (at the same time) to try to use simultaneously 4 monitors (internal + 3 external (one VGA and 2 DVI)).
- Internal monitor + DVI external monitor A on DP2DVI Active DisplayPort adapter + VGA external monitor on DP2VGA Passive DisplayPort adapter + DVI external monitor B directly on the DVI output of the docking station: OK (4th display cannot be enabled).
- Internal monitor + DVI external monitor A directly on the DVI output of the docking station + VGA external monitor on DP2VGA Passive DisplayPort adapter + DVI external monitor B on DP2DVI Active DisplayPort adapter but directly connected to the DP port of the laptop: OK.

DP adapter details are as follows:

HP DisplayPort to Dual Link DVI-D adapter (NR078AA).
HP DisplayPort to VGA passive adpater (AS615AA).

 

Same reason as those AMD desktop cards could do stuff like 6 displays while nVidia was stuck on 2 for several years.

They are different chips with different features. That's the reason

 

Sorry friend but the user you quote has a 8560w with AMD FirePro 5950M, not a NVIDIA GPU!!
