Hyper-V and latest driver problem

[JJarm1]

I have problem with .4501 driver provided by Lenovo. Either I have to disable Hyper-V and Vt-d from BIOS or uninstall hyper-v driver. Did the latter!

If I do install hyper-v and connect for example a TV to my miniDisplayPort>HDMI cable (Lenovo), Windows shows me something like 6 external monitors when actually only one connected. Occasionally screen starts to flicker in different colors. This did not happen with the old driver.

Previously I had a problem with HDMI audio. Finally I found a solution to that issue. I had to reinstall Microsoft Visual C++ 2005 redistributable package for my OS (64 bit Win 10 latest production release).

There CLEARLY is a severe driver problem. Can you make installation check that correct version of redistributable files are installed?

Wrong attachment. Can you please delete it?

Here is correct one

Hello Jampe,

Please test the system behavior with the following drivers:

1. Beta 4539 directly from Intel: http://intel.ly/2dD3t5y http://intel.ly/2dD3t5y

A. In order to easily install these drivers, please download the drivers, disconnect the system from the internet B. Then follow steps here: http://intel.ly/1PdmvLd http://intel.ly/1PdmvLd2. Test the system with Windows default drivers A. To get them, uninstall the current drivers from the device manager B. Restart the system and run Windows 10* updates

While uninstalling the current drivers, please make sure to select "Delete the driver software for this device" as in this screenshot.

Please let me know how it goes.Regards,Esteban C

I am afraid beta driver you provided is not compatible with Thinkpad T440s Graphics adapter (HD Graphics 4400).

Jampe,

The release notes indicate it is compatible, and I have installed this driver on systems with Intel HD Graphics 4400.If you followed the instructions noted on the second link provided (B. Then follow steps here: http://intel.ly/1PdmvLd http://intel.ly/1PdmvLd) probably the manufacturer blocked third party drivers installation.

At this point, my recommendations is to contact them and advise them about the issue, try to find another way to install the drivers provided or get one of their drivers that works with the system.

Please let us know how it goes.

I do see more or less the same problem as the original poster on a Dell M3800 (HD 4600): No Intel control panel and broken multi-monitor support when Hyper-V is enabled.

This happens with all 45xx drivers (at least up to 4531 from the latest Windows 10 beta), 44xx work fine (I'm currently back to 4474).

Just like Jampe, I have problems with the beta 4539 driver. It installs with the instructions you provided but it does not load after booting because of a signing or corruption problem.

Did you actually try to reproduce the problem on one of your test systems? I.e., turn on Windows's Hyper-V feature?

jkreileder,

Thank you for the information related to previous driver working with this configuration.

Would you please provide me with your system report in order to have 2 different (if applicable) scenarios to attempt to replicate this in our lab?

Here is how you can get the report:

-Access: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility

-Download the utility-Scan your system with the utility-Export the report (hit next and then save) and attach it to your answer with the advanced editor option (reply button and then check upper right corner)Regards,Esteban C

Here you go.

Apart from the missing Control Panel with the 45xx drivers when Hyper-V is enabled, the problem I see with multi-monitor support is as follows: The internal and external display which should show up as display "1" and "2" are combined into a single "1|3" display and two additional displays (which have no hardware equivalent) "5" and "6" show up. I found no way to split up "1|3" and remove the two additional entries. Only going back to 44xx helps.

Thank you for the information provided!

There is one last thing I would like you to fill out, this form: /thread/77761 https://communities.intel.com/thread/77761Regards,Esteban C

Hello jkreileder,

Just checking if you still require support for this matter.

Yes of course! Just waiting for you to fix this issue. I have provided information you requested...

It won't get fixed just by itself, will it?

[JJarm1]

Today I installed version 20.19.15.4531 provided By Lenovo. This issue seems not to exists in that version.

Hello Jampe,

Thank you for reporting this issue to us.

I would definitely recommend using the drivers provided by the OEM. I do wish to confirm that we have been able to replicate this issue in our test lab with builds .4501 and Beta .4539.

Once I have more details on a new generic driver I'll post them here.

Regards,

[idata]

Hello Jampe,

I just wanted to verify if you were able to get the drivers from the OEM and get them tested?

Lenovo provided new .4531 version of the driver. It work better. It appears that 4501 was faulty driver package

[idata]

Jampe,

Problably there was something extra required for your system to work with Hyper-V that our generic drivers didn't contain (generic: not designed for an specific device).

It is great to hear the system is working better with the drivers provided by the OEM.

In case you require any further support, feel free to reach us again.

Don't get me wrong here! Both intel and OEM drivers failed (.4501 version). No difference here! earlier versions were ok as well as later version. So I think there was something wrong or corrupted in compilation or packaging of version .4501

Hello Jampe,

I apologize for the misunderstanding.

I will be reporting this to get further investigation of the issue.

Hello Everyone,

I would like to let you know that the following issues show as fixed in our latest 15.40 internal build:

1. Multiple non-existing monitors show up when Hyper-V is enabled.

2. Graphics Control Panel is not available when Hyper-V is enabled.

We appreciate your patience while we post this new driver on DownloadCenter.intel.com.

I'll update the following thread once the driver is officially released:
