NUC6CAYH - HDMI output over 50Hz - periodic screen tearing - HD Graphic Driver Bug Report

Hello to All.

This discussion serves as an official bug report submission for the Intel HD Graphics Driver concerning the NUC6CAYH kit.

This issues has been described before by MannT in this MannT decided to give up on the product.

MannT describes the issue very clearly in his question. If I can add something to his description would be that this "interference" he describes happens every few seconds and becomes utterly annoying after a couple of minutes. This is a total deal-breaker.

The issue is also present using lower resolutions and even higher refresh rates, e.g 1280x1024@75Hz. It seems that irrespective of the resolution if the refresh rate is higher that 50Hz, the issue manifests itself.

I have spent the last 8 days (since I first bought the nuc) trying to troubleshoot this annoying issue and determine whether this is a hardware incompatibility and therefore I needed to return the product, or a software issue that could eventually be resolved.

I have used different HDTVs/Monitors, namely: UE55B7000WW and LT32E310EX. Both exhibit the issue in every different HDMI input of each and using various different HDMI cables including HDMI 2.0 certified cables.

I have updated the BIOS to the latest 0040 firmware. The issue is still there.

I have updated the LSPCON firmware from 1.60 to 1.66. The issue persists.

I have also used different power supplies to power the NUC (12V DC 75Watt Max) with the said issue stil persisting.

I am running windows 10 x64 enterprise and all drivers are up to date and were downloaded from intel's website.

EVERY other computer I own can do 1080p @60Hz using the above mentioned HDTVs/monitors without any issues.

The NUC6CAYH is advertised and sold as ABLE to do 1080p @60Hz, hence the workaround of running my refresh rate @50Hz is completely out of the question.

Anyway, as I mentioned I am not here to accept suggestions from people on what to try next. I wasted enough time and I was lucky enough to pinpoint the problem to the Intel Graphics Driver. Therefore, I am here to submit this as an official bug report and hopefully have Intel's engineers reproduce, acknowledge and eventually fix the issue in one of the upcoming driver releases.

My NUC remains issue free when I use Graphics Drivers up to and including 21.20.16.4590.

As soon as I update to any newer drivers (starting from 4627 up to and including the latest 4729) the issue appears. I did not bother to test 4614 as it was a beta driver and I was not interested in using a beta driver anyway. So I do not know if 4614 has this issue or not.

In case Intel refuses to acknowledge this issue as a graphics driver bug, I would like to know ASAP and in writing as I want to return this product as defective and not get charged any restocking fees etc. I am happy with the unit as far as everything else is concerned, but there is no way that I am going to keep it either using an outdated driver or at a lower refresh rate than what the product was advertised and sold as. I am sure that Intel will choose to stand by its products and not lose another customer as happened already with MannT.

If Intel has another process in place for submitting driver's bugs, I'd be happy to follow it as soon as you let me know about it.

Please do not close this discussion unless an official acknowledgement or denial of the issue as a driver bug is given by Intel.

Looking forward to a very prompt resolution of this problem.

Regards,

KP.

Hi KPed: Thank you very much for joining the Intel® NUC communities. We are sorry to hear the NUC is not working as you expected and we apologize for any inconvenience.

 

 

In order to address this driver issue, we will do further research on this matter, as soon as I get any updates, I will post all the details on this thread.

 

 

Any further questions, please let me know.

Hi KPed,

 

I am sorry to hear about this issue you have been facing with one of our products, I work for Intel Customer Support and we have been investigating this issue with no results, meaning that I have not been able to duplicate it in our laboratory.

I see that you have updated your system to run latest BIOS (version 40) and latest Graphics Driver (version 15.46.2.4729) and you reported that version 21.20.16.4590 works fine. Is there any specify reason why you need to run latest graphics driver? Perhaps any issue addressed by a more recent driver?

I would recommend that you contact Intel Customer Support and make reference to case 02980307 so that we can find a way to resolve this issue. Here is our contact us information: https://www.intel.com/content/www/us/en/support/contact-support.html https://www.intel.com/content/www/us/en/support/contact-support.html

By the way, a bug report was filed but there is very little we can do about it if we cannot replicate the issue.

Regards,

Ronny G

Hi !

Same issue.

Random screen tearing/flickering at 1080p@60Hz via HDMI (no issues @50Hz).

Its not awful, but annoying.

It looks like this:

| |

| |

| |

Barebone: NUC6CAYH

BIOS: 0041

HDMI Firmware: 1.66

RAM: Kingston KVR16LS11/4 x 2

SDD: Samsung 850 PRO 256Gb

OS: Windows 10 Pro x64, 1703, 15063.540

I tried to use various HDMI cables without success.

Same monitor/cables works with other sources without issues at 1080p@60Hz.

I tried different versions of drivers:

4729 - Issues

4771 - Issues (new one)

4664 - Issues

4590 - OK (my current choice)

4551 - OK

Hi,

I'm also having the same problem of the display "tearing" occasionally in the lower half of the screen.

I happens also at 50 Hz, but less frequently.

Has anyone found a solution yet?

I've got th latest drivers and latest bios, and all HDMI 2.0 cabling...

Hi, Ramy

This topic is marked as "Assumed Answered" by Intel.

... assumed that driver downgrade is a possible workaround...

Hi,

I'm glad they thought so - it didn't work for me...... :-(

Good money down the drain?

Ramy,

I went into control panel and then devices and used the download old driver. That seemed to work.

semplice,

per Intel è più conveniente ritirare il prodotto a poche persone, che risolvere un problema per molti.

La new economy = poco interesse sociale e molto individuale.

Hanno solo un obbiettivo:

L'utile da presentare alla trimestrale al nasdaq.

Ormai assumono solo mediocri.

Exactly the same problems here. Driver 4551 solved my problems, all newer drivers cause the tearing again.

Come on Intel, this seems to be a driver problem so put some effort in finding the error and fix it!
