HD 4000 triple monitor works in Linux, not Windows

[DLars1]

I have a Lenovo T430 with Intel HD 4000 and the Lenovo Mini Dock Plus. I have connected two identical displays using the DisplayPort connectors on the dock and would like to keep the laptop's internal display also active.

I've tried various combinations, but no matter what I choose, I can only have two displays active at any given time in Windows 8 (64-bit). The Intel website shows a third display option will appear in the control panel, but I have yet to see it appear. I even tried updating to the latest driver available on Intel's website without any improvement.

What's very odd is this same laptop and configuration works fine in Ubuntu 11.04 with all three displays enabled. It seems very odd to me that the Windows driver is limited, yet the Linux driver is not.

Is there any trick to force the third display to enable? Is this a problem with Windows 8 or a limitation of the driver?

[JRott1]

I too am frustrated by this issue. I specifically researched and paid extra for the Intel HD 4000 graphics card so I could run 3 displays, per the marketing literature for this card. Like others on this thread, I am disappointed that the performance of this card is not as advertised. Also like others, I'm keenly interested in a solution.

I can definitely say that I'll think twice about buying Intel cards going forward. If I could purchase my computer again, I'd pay $100 for another card that works as advertised out of the box and avoid the hours and hours of headache the HD 4000 has caused!

Looking forward to a solution ASAP...

Any update on this I have the same issue, I notice the biggest difference from my config compared to Roberts is my built in monitor is LVDS not embedded display port, it that just they way a manufacture set the display or is it a function of the driver.

[DLars1]

LVDS is the internal connection type of the laptop's display. It's not possible to change it.

Your only option for Windows is to use two active DisplayPort displays. If your dock doesn't offer two DisplayPort ports, then you're probably out of luck, other than going for a USB display or something like that.

Based on the response from Intel thus far, I don't expect this issue to be resolved. Their test unit's internal monitor uses DisplayPort, so they are unable to reproduce the problem. Even if they did reproduce this on a laptop with LVDS, I don't hold out much hope for a resolution as even the documentation claims only LVDS+DP+DP will work, even though Ubuntu shows us this is not a hardware limitation.

The real trick is getting the message through to the driver developer. I'm convinced if he/she/they were aware of the problem it'd be a trivial fix for them, but we're unable to reach that tier. As a software developer myself, I understand the need to filter feedback from the users, but Intel goes overboard and makes it impossible to submit obvious bug reports like this to the development teams due to a lack of understanding from the support staff.

[DTeag]

I agree its kinda of silly that it works on Linux Mint15 on my laptop but not in windows. On my old ubuntui install I even used the intel linux drivers from 01.org and it worked also.

There is something I would like to clarify for this issue. Please be aware that the video driver does not support USB monitors, this includes monitors connected into a USB dock, and then connected to the computer. However, the operating system does support monitors connected via USB dock. It will not be shown in our CUI, but it will be shown in the OS's Resolution menu (right click desktop > Screen Resolution). The two external displays connected to the dock should be populated in this menu.

drlarsen, in your case as you are using a using a Lenovo USB 3.0 dock, it is important to make sure you have updated your USB dock driver (if they have already tried the latest provided by Lenovo, they should then try the latest driver provided by DisplayLink @ http://www.displaylink.com/support/downloads.php http://www.displaylink.com/support/downloads.php

So, please check under Microsoft* Screen Resolution menu, and attempt to enable 3 display connection from there.

[DLars1]

I'm not using a USB 3.0 display. I'm the one who worked around the shoddy Intel display drivers for Windows by using Active DVI-to-DisplayPort adapters.

That of course doesn't help people who don't have two DisplayPort connections on their dock. What would help them is fixing the display driver so that DVI devices run off a single clock, as is the case in your Linux driver.

[JBran7]

I'm guessing Intel is going to have a little more of a fire under them now that 8.1 production has rolled out.

The HD4000 driver is tanking everywhere in the community, and no longer among early adopters of 8.1 Preview.

Audio problems / video playback issues / resolution issues / multiple monitor issues...... Basically the driver is failing in everything its SUPPOSED to be doing.

[JRott1]

drlarsen:

When I checked the graphics control panel for my system, I get the following information:

build-in display:

display type: digital

connector type: LVDS

device type: LFP

Monitor DELL 1905FP ("monitor 1"):

display type: analog

connector type: VGA

device type: CRT

Digital Display DELL 1907FP ("monitor 2"):

display type: digital

connector type: HDMI

device type: DVI

From your earlier post in this thread about determining Active vs. Passive, I don't see that the "Connector Type" or "Device Type" parameters have the value "DisplayPort". I would assume that since my triple monitor setup doesn't work (I'm trying to use built-in display + VGA monitor + HDMI monitor) I have passive connectors, but does the information about confirm that?

Thanks for your help.

*** EDIT ***

After reading more, it seems that since my built-in display is LVDS (instead of eDP), the only way triple monitors will work is the two other monitors are connected via DisplayPort. Since they are connected via VGA and HDMI, not DisplayPort, this will not work per Intel's literature.

Sorry to distract the thread. I didn't fully understand the limitations / problem until reading this and other threads.

I re-iterate my earlier comments that I'm frustrated that this video card was marketed with the statement that it supports a triple display, only to find out that the reality that triple display is only possible if the computer meets one of a narrow set of specific hardware criteria. I'm frustrated, disappointed, and unlikely to buy an Intel card again if I have a choice.

Microsoft has an updated Windows 8.1 driver for the HD 4000 available in the Windows Update Catalog that has solved the crashing issues for me:

http://catalog.update.microsoft.com/v7/site/Search.aspx?q=HD%204000 http://catalog.update.microsoft.com/v7/site/Search.aspx?q=HD%204000

You'll need to use Internet Explorer to use the site and the relevant files are dated Oct 1, Version 10.18.10.3316. The 95.0 MB file is for 64-bit systems, the other for 32-bit.

I hope that helps you out.

[DLars1]

You've got it right, Joe. The only way you'll get it to work is if you have a dock with two DisplayPort connectors, and then you'll need to use Active DisplayPort adapters. Either that, or switch to Linux where the display driver doesn't have such silly limitations.

[JBran7]

Vs. 10.18.10.3316 might cure the crashing issue, but I still can't get multiple monitors operational with this version. Its also the latest available through the Intel website.

[DArce]

If you have any displays connected through a USB 3.0 dock, all displays on the dock are considered "USB" for the purposes of driver support. That is why they do not show up in the Intel(R) Graphics and Media control panel, but should show up in the operating system settings.

[EAnde12]

This thread seems dead but thought I'd try to revive it since also would like an answer to this issue!

My setup is a HP 2170p that has one dp in the pc and then a port replicator that has another one.

Internal display is LVDS and then I have one HP ZR2440w with DP connection.

What I want is to be able to connect a third display together with internal and the HP and I have been trying with two different dell displays.

Dell 1905FP and Dell 177FP

All the setups I have tried:

DP - DVI - LVDS

DP - VGA - LVDS

DP - DVI - VGA

DP - DPtoDVI(passiv) - VGA

DP - DPtoDVI(passiv) – LVDS

DP - DPtoDVI(active) – LVDS = Should work but does not.

DP - DPtoDVI(active) – VGA = Only one that works but not what I'm looking for.

After this I bought and active DP to DVI adapter and tried:

DP - DPtoDVI(active) - LVDS = This still doesn't work. Now intel config lets me choose 3 active monitors and config seems to believe all three monitors are working but only get display on one of the DP ones.

I did however manage to get: DP - DPtoDVI(active) - VGA to work but what I need is the internal display and both according to you and HP it should work.

Here is a document where HP says this exact configuration should work:

http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/mostViewedDisplay?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_efb5c0793523e51970c8fa22b053ce01=wsrp-navigationalState%3DdocId%253Demr_na-c03767437-2%257CdocLocale%253Den_US&javax.portlet.tpst=efb5c0793523e519... Most viewed solutions for HP ProBook 4540s Notebook PC - HP Support Center

with this addition:

"NOTE: In this table, display combinations with dongles are not mentioned. However, a DVI display can connect with a DP-to-DVI dongle, and an HDMI display can connect with a DP-to-HDMI dongle."

So my question, when are you going to solve this windows driver limitation since it's obvious it is a driver limitation when it works fine in Linux.

*Edit

Have tried some more and after a lot of different configurations I finally got DP - DPtoDVI(active) - LVDS to work but seems extremtly unstable.

Get artifacts and disconnects on both DP and DPtoDVI display intermittently and whats even weirder is that if I disable the third display and run on only DP and DPtoDVI I only get video on the secondary monitor but if I connect VGA or LVDS I sometime manage to get video on all three.

Hi Erik.Andersson,

The triple display configuration can be obtained by using the following configuration:

If two of the displays are DisplayPort* monitors

If one of the displays is an Intel® Wireless Display (Intel® WiDi)

If the built-in display is an Embedded DisplayPort1 (eDP)

You can also get more information at the following link:

http://www.intel.com/support/graphics/sb/CS-033714.htm?wapkw=(triple+display) http://www.intel.com/support/graphics/sb/CS-033714.htm?wapkw=(triple+display)

It is also important to say that it is recommendable to use straight connections and as you mention the active adapters also will work.

[DTeag]

Yet know one has be able to explain why the exact setup I have right now works in Linux but not Windows, is this a Windows Kernel Issue or and issue with the Driver?

[Kevin_M_Intel]

It is possible to set triple display on windows using the Intel® graphics controller. I have set this configuration with Intel® boards without a problem. We strongly recommend using direct connection (without adapters) and updating the drivers to latest/

Hi! This thread is very useful and helpful for me and maybe for persons who try to set up triple display monitors on Intel HD 4000 Graphics.

Thank you Erik.Andersson and kevin_intel for useful information!

I use the HP 2570p laptop (within Intel core i5 Ivy Bridge and Intel HD 4000 Graphics) with Windows 7 Enterprise 32 bit. (I wonder why 32 bit OS selected by the IT administrative section of my company.)

Because I also use its docking station, there are three available display connectors, a VGA and a display port on the docking station and another display port on the right hand of the laptop.

I want 3 or 4 display monitors in extended mode in my job.

This laptop does not have an Intel® Wireless Display (Intel® WiDi) module nor an Embedded DisplayPort1 (eDP) but LVDS, so I have to choose the first condition, says "If two of the displays are DisplayPort monitors."

Sadly, I just have old LCD monitors that have only single VGA connector or double (VGA and DVI) but no DisplayPort. Using two DP to DVI active adaptor, I can get the triple display monitors working condition, that is following,

DPtoDVI(active) - DPtoDVI(active) - VGA, and

DPtoDVI(active) - DPtoDVI(active) – LVDS (monitor in laptops).

If exchanging each DPtoDVI active adaptor to its passive adapter, that just cause to get the decreased the maximum number of monitors to the double. Thus DVI does not seem to compare to DisplayPort, although both are digital signal transports, DVI connection seems to need an additional clock generator in an active adaptor.

First, I got the information Intel GPU core has only 2 pixel clocks and 2 DisplayPorts can share one pixel clock, and the other one can use for VGA or LVDS in somewhere community board. I thought that it needed total three signal transports contain two digital signal transports and one analog VGA transport, so I expect DP to DVI passive adaptors are enough to work it, but these were not working enough.

To tell the truth, I did not know there ware the kinds of DP to DVI adaptor, active and passive. What active?

When I was searching it in Google, I understood there was a clock generator chip in "active" adaptor and passive one did not have it. These of recent products looked like the same figures, only difference was a chip inside which could not be seen. I bought "active" adaptors from Amazon, but I had even understood it really "active", since I had seen all the devices connected to work it out perfectly. Watching it well, there are only three differences I found, gold-courting in connection port part, little short length of the cable, inside shape of the connection cover, it seems no relative to work or not.

.

I do not know which a clock generator in active adaptor is equal to a GPU core pixel clock, or not. Simply counting the number of clocks is 4 that more than 3 monitors. Does it mean "1 clock　remains"? Or the clock generator is not a pixel clock and that can just help it?

Because I am not an IT specialist, so I may not understand it soon. (^^;)

[MPowe3]

So - just to confirm my experince, mine wouldn't work with a DP, DP-DVI and VGA combo. Luckily, two of my monitors are DP, so I swapped out the DP-DVI for a straight DP cable. The final setup (DP, DP, VGA) worked instantly.

I'm running Win 7 on a HP Elitebook 2570p with the standard dock. You need to use the DP port on the dock and the one exposed on the right-hand side of your laptop.

[PMans]

I dual-boot Windows7x64 and Ubuntu 14.04 on a Lenovo T540p for which I have the dock, and a pair of HP E241i monitors (1900x1200).

The only way I can get triple-head is to use the VGA connector on the side of the laptop (not the one on the dock), the DVI port and the internal screen, this with Linux and Windows.

I have been unable to get the three video connectors on the dock to produce independ video outputs - the VGA connector on the dock is always a clone of the DVI video which also seems to be hard-wired to the Displayport connector! I can't get them to be independent.

I also have problems when using with the dock's VGA connector: the monitor won't sync accurately and the picture is shifted to the right with the HP E241i monitors.

If I can find an adaptor, I'll see if I can get the laptop's own miniDP connector to perform independently of the dock's DVI/DP connector. It's quite annoying to have to run one monitor off VGA, it's noticeably unsharp compared to the other.

[Kevin_M_Intel]

I understand and you are right! The image of VGA is different than using other connections. We do recommend using direct connection (no adapters) since the image can be affected when using it.

Hello

I'm reopening this thread - rather inactive lately: either everyone gave up, or found the solution...?

A bit long, but.. it cannot be explained in details in one sentence: except: DisplayPort went dead on win7 out of the blue, but works on ubuntu... of course on same cable(PC:DP-DVI:Monitor).

I just want' a clear answer (pref.from the maker of the card: intel hd4000) if there is one.

How to make DisplayPort work on (OEM) Win 7 Pro/x64, HP Probook 6470b.

Here is the situation: I don't want 3 displays... heck I just want one to work via Displayport - it did for 5 months...

Situation:

1. i needed external display (only DVI-D Monitor available) .

2. i got DisplayPort to DVI-D cable: DisplayPort hooked to DVI-D input of SamsungSyncmaster 245B worked great!

(up to 1920x1080: no problem: closed the lid an auto.got 1920x1080 on external monitor):

3. I took laptop and hooked it to TV: DisplayPort->HDMI: no problems...

4. One day it "decided" to stop working... and I don't think the DisplayPort is broken: something else is (according to all troubles people go through I would say I was very lucky to get away with this: e.i. getting the pisture from DisplayPort..) - in fact it's not broken: when tested on Ubuntu it works, so HW is ok.

5. I reinstalled intelHD 4000 drivers to new ones (v.dec2014) - even though the things worked with old one (v.jul2013), going to restore points,...

6. Tried...well almost all there is to be found on internet (where else?) - nothing works, though DisplayPort works with no problem on ubuntu (makes you think...doesn't it?)

7. Tried DisplayPort to VGA^ - vga monitor not even detected, nothing... as with dvi monitors, or hdmi (TV)

(^ which works perfectly (i'm "lucky" i guess) on other laptop (yes, hp proobook just year or two older than the one in question: with plain Intel HD (not hd4000) - same OS (win7 pro x64)

*I know it maybe older version of monitor. but hey... it works with ATI Radeon (5450hd from desktop pc): so: it's not monitor fault

** VGA out works ok all the time - but i cannot hook dvi monitor to it (and i don't want to!).

So it seams: Display Port is somehow not even in Win7 picture: like it's not there - but that's what driver's do, don't they? Or is there a super hidden switch in Windows to enable DisplayPort? (I don't see it...).

again: It's not HW: it works with Ubuntu (i'll keep saying that, so it's clear that it's windows/intel (later one?) thing: i don't think it's HPs error, really).

1. How to check if (maybe) DisplayPort doesn't work in wondows? And what to do?? - it works with Live ubuntu so it's not HW failure...

2. Is there a SIMPLE solution? "Simple EXE" to sort things out? (should be by now, or Intel & HP(?) just don't care?)

3. Would win 8.1 solve anything? - I'm not really eager to migrate because win7 is just ok it is: no need to chnage for now - waiting next Win OS (10?): so, planning to skip win8, as I did skip the vista failure (excuse my language - but let's be real: it was big fail)

4. Is there a separate DisplayPort driver? (if so: I did not found it on HP 6470b download page... - maybe (if there is one) it got corrupted?)

5. Is "active" adapter any good? - would that work? (eg. "BIZLINK Display Port DVI-D DualLink Adapter USB Powered Cable?") - but the "problem" is that I'm ok with 1920x1080 (don't need higher res. for now) - and I have a cable that works ok- tried on other laptop...

6. USB to DVI?.. yes i'm that desperate - does it work like plugging monitor to VGA/DisplayPort? - maybe odd question, but i'm not familiar with this adapters and really don't know what to expect? (does it go to 1920x1080?)

I'm so tired of hours spending reading: that I should even reprogram EDID on DVI monitor: come on.. but it would not change anything: since it does not get detected by DisplayPort - and monitor works with dvi signal from other PC...

Please, give me some feedback: I'm not re-installing OS because of this: it's.. plain stupid solution: and I'm not sure if it's going to work again anyway - or if, for how long?...

Long post I know: just don't give me: reboot with all cables plugged in or go into safe mode..

Thank you: looking forward for possible solution...
