Thinkinh of buying the P50 for software development work. Is it possible to drive an external 4K@60hz monitor using only the built in Inte Graphics? i would like not having th fans run constantly just to be able to drive the monitor which I suspect might be th case if the nVidia GPU is require (only available with th M2000 here).

You have the Xeon?'
See graphics section on:
Using the display port, it should be able to do it.
for the i7.
hope this helps.

The ThinkPad P50 as equipped with the Intel Xeon E3-1505M, which uses the Intel HD P530 for its integrated graphics processor. Looking at Intel's Product Information & Documentation page doesn't seem to have any information about the maximum number of monitors that can be driven, but ARK page for the CPU lists the following:
|Processor Graphics ‡||Intel® HD Graphics P530|
|Graphics Base Frequency||350 MHz|
|Graphics Max Dynamic Frequency||1.05 GHz|
|Graphics Video Max Memory||1.7 GB|
|4K Support||Yes, at 60Hz|
|Max Resolution (Intel® WiDi)‡||1080p|
|Max Resolution (HDMI 1.4)‡||4096x2304@24Hz|
|Max Resolution (DP)‡||4096x2304@60Hz|
|Max Resolution (eDP - Integrated Flat Panel)‡||4096x2304@60Hz|
|Max Resolution (VGA)‡||N/A|
|Intel® Quick Sync Video||Yes|
|Intel® InTru™ 3D Technology||Yes|
|Intel® Wireless Display||Yes|

A little more digging gives us the 6th Generation Intel Core Processor Family Datasheet, Vol. 1, which states:
Multiple Display Configurations (Dual Channel DDR)
The following multiple display configuration modes are supported (with appropriate
The digital ports on the processor can be configured to support DisplayPort/HDMI/DVI.
So, my best guess is that it will drive at least one external monitor of 4096×2304 at 24Hz, and probably at 60Hz as well, but that depends upon how the external display support was engineered.
If you want a definitive answer, you'll need to contact Lenovo and ask pre-sales support directly to confirm what resolution and refresh rates are supported for external monitors. Please keep in mind this forum is a peer-to-peer forum and many of the folks answering questions here are volunteers and not Lenovo employees, so sometimes you may need to check directly with your local Lenovo office on Monday.

Thanks all for responding. Actually, what I don't want is fan noise just for running an external 4K monitor doing non graphic intensive work. I assume that the Nvidia GPU will consume more power thus the question, but I really don't mind what GPU is used as such.

I'll see if I can set this up to take a look at it. I suspect the onboard Intel graphics can support this, but will set it up in the lab to double confirm.

No, the Intel GPU can´t drive any monitor. All display-outputs are always connected with the Nvidia GPU, so it has to be enabled to be able to connect an external screen.
However, don´t worry about the fan-noise. Merely connecting a screen won´t lead to any fan noise.

I'm in agreement with ibmthink based on what I'm seeing. The Intel graphics display properties never seem to recognize another display (other than the ThinkPad display) regardless of what is plugged into the HDMI or miniDP ports. The NV control panel, however, always recognizes displays in those ports. So I believe the external graphics ports are all being routed through NV.
I don't think fan noise will be a concern if the external screen content is not taxing the GPU. I was just running 1 and then 2 additional 28" 4k displays in extended mode, and didn't notice any difference in fan speed.

Seriously? It sounds a very inefficient use of the p530 graphics. So if you open the gPu monitor it will show as the nvidia gPu is in use even if your staring at a blank desktop? Anyone could post a screenshot to that effect? I guess I don't want to believe it
