[sodaboy581]

So, I made a detailed topic which was marked as spam for God knows why, and I'm going to repost it because it's a serious issue.

This time I'm going to attach the prerequisite bug report files.

Thanks.

Hello sodaboy581,

Thank you for posting on the Intel®️ communities. 

In order to have a better understanding of the issue, please share with us the following information: 

1. Does the issue occur when using a straight connection (DP to DP cable)?

Also, the latest driver for your Intel(R) NUC is version 30.0.101.1191, this driver has been customized and optimized to work specifically with Intel® NUC products, different from the driver version 30.0.101.1404 as this is a generic driver without any customization. Please perform the clean installation of the driver following the steps in the article "Clean Installation of Intel® Graphics Drivers in Windows*" and using the latest driver for your system. 

Let us know the results. 

Regards,

I'm using a Mini DisplayPort to DisplayPort cable.  There isn't any way to use a DP to DP cable because the Intel NUC does not have a full size DisplayPort connector on it.  You basically can only connect a device through Mini DisplayPort, HDMI or USB-C.  So, I'm using Mini DisplayPort to DisplayPort cable to take advantage of all the abilities of the Iris Xe including Adaptive Sync.

I can attempt to use version 30.0.101.1191 when I get home, though I'm already quite OK with 30.0.100.9955.  I can do it for SCIENCE, though.

Hello!  I want to update you.  I installed 30.0.101.1191 and the issue immediately returned during the installation of the driver, no doubt!

Immediately DisplayPort no signal.

Going back to 30.0.100.9955 for now!

[sodaboy581]

Actually, for kicks, since I've tried all the 101 versions now except 1069, I'm going to give 30.0.101.1069 a whirl and see if it has the same issue.

That would then tell me at what version, EXACTLY, this problem started to occur.   Because 30.0.100.9955 is perfect.

[sodaboy581]

OK, so, 30.0.101.1069 is actually good!  It is the only 101.xxxx driver that is stable for me!

It looks like the issue is introduced in 30.0.101.1191.  So, to summarize...

30.0.101.1404 = Broken.  Works off and on, has DisplayPort NO SIGNAL at boot up randomly and also doing full screen enter/exit on occasion. 

30.0.101.1340 = Broken.  Same problem as 30.0.101.1404

30.0.101.1191 = Broken.  Same problem as 30.0.101.1404 and 30.0.101.1340

30.0.101.1069 = Works just fine.

30.0.100.9955 = Works just fine.

..... all the way down to at LEAST 27.20.100.8935 work just fine, with no DisplayPort output issue.

Hi sodaboy581,

We tested the latest driver available validated for the NUC11PAHi5 on the web: GFX version 30.0.101.1191 and we had no issues getting signal when using DP. We tested various display models, the one I have is a Dell OT9MJ3 Monitor.

This may be a compatibility-related issue Monitor/Driver, we'll keep an eye on it and for now, the only recommendation would be to stay on version 30.0.101.1069.

Is Windows Update pushing Driver version 30.0.101.1191?

Regards,

[sodaboy581]

Windows Update does not push the latest version.  In fact, if I leave it up to Windows Update, it only downloads 27.20.100.8935.

I, myself, seeked out newer versions because I knew they existed.

30.0.101.1069 is perfect and I'm just going to stay on that for now, I guess.

The later versions DO give me a signal on DisplayPort, but it's a coin flip if I get one at startup.  It's also a coin flip if the signal will remain after entering or exiting a full screen game or changing refresh rates.

Basically, it's entirely random and not stable on the later versions, so I have to stick to 30.0.101.1069 with my particular monitor, unfortunately!

Thanks for the reply!

Hi sodaboy581,

Yes, as you said it, I would recommend that you stay with version 30.0.101.1069 which works just fine, at least for now.

Please be aware that the latest GFX driver version validated for the NUC is version 30.0.101.1191 that you mentioned that it is also causing issues.

I would not recommend any other driver version but in case you want to try something else, I would go for the Intel Graphics - Windows* DCH driver version 1641, here is the URL https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html
