Display Not Detected After Application of KB4284835

Hello,

I am posting this request for help under "devices and drivers" as I suspect the problem might be driver related, but I would be happy to have this corrected to "Windows Update" if more appropriate.

I have a single hardware platform that uses removable 2.5" SSD drives in order to permit me to "dual boot" between 2 different versions of Windows 10 on the one PC. I have 2 licensed [both purchased] copies of Windows 10 Pro 64-Bit for this machine. Both have recently been updated, first to build 1803 [on May 27th] and then to the "Cumulative Update for Windows 10 Version 1803 (KB4284835).

The hardware configuration for the system is:-

Motherboard: MSI Big Bang Power II (silly name, but actually a quite decent board)

GPU: nVidia 1080GTX

Disk: all Samsung 850 Pro SSDs [total 4 volumes, ranging 256Gb to 1Tb]

Audio: Creative X-Fi Titanium

There are 3 monitors connected to this machine. All are identical, Dell U2415W monitors, with 60Hz, 1920x1200 displays. The configuration of the monitors as seen on my desk are:-

Left Screen - DisplayPort on the GPU, mini-DP on the Monitor

Centre Screen - DVI-D on the GPU, HDMI on the Monitor

Right Screen - HDMI on the GPU, HDMI on the Monitor

There are Windows-level differences between the two builds:-

1. "Office Build"

This runs MS Office 2016, graphics software such as Adobe Photoshop CS5, Lightroom, etc

This build does not use nVidia's "surround spanning" virtual desktop technology.

2. "Games Build"

This runs the Steam Client, the Origin Client and a bunch of stand-alone games titles

The build does use the nVidia "surround spanning" virtual desktop technology.

After the application of the 2018-06 Cumulative Update for W10v1803, I now have slightly different symptoms on both of my "builds":-

1. Office Build - I have only 2 working monitors, the "DisplayPort" screen [my left monitor] is not recognised by this Windows Build

2. Gaming Build - the machine boots, I see the BIOS POST screen, I hear the Windows Audio sound as the system comes up, but nothing at all displays on any of the 3 monitors - it "looks" like an entirely dead machine...

This is not the first time I have experienced this issue with a major Windows 10 Update.

Steps Taken

Since I am unable to do anything with the "Gaming Build" at the moment, I have instead tried to work with the "Office" build.

I have downloaded the latest nVidia Driver direct from the nVidia web site. This is driver version 398.36, using the file,

398.36-desktop-win10-64bit-international-whql.exe

This evening I have tried to refresh the nVidia driver in the hope that doing so would "allow" my office machine to see all 3 monitors and work again. Initially I performed a generic installation [a basic upgrade] and asked the installer to download the driver and the PhysX components only [I do not use HDMI for audio and I do not have 3D capability running via the GPU.

This "upgrade" proceeded smoothly, the machine rebooted OK... but I still only have 2 monitors.

I then repeated the "upgrade" process, except this time I asked for a "Clean Installation" - which warns that it will wipe out all preceding configuration files and parameters and give a "clean" installation.

Neither approach made any difference, I still have just 2 working monitors. Trying to use the more advanced display detection capabilities in the nVidia driver produces this result:-

So it "sees" something and "sort of" recognises it as a digital display. However, I am unable to set it active, and attempting to do so seems to hang the mouse cursor for a period of about 15 seconds.

As far as the "Gaming" build is concerned, I am completely at a loss as to know what to do. For what it is worth, I had a similar result the last time a windows update caused me display issues. I was able to repair the office build with help, but the Gaming build required a completely clean Windows installation.

I would prefer not to be left facing that option this time around.

Any guidance or assistance that anyone can offer with this would be very much appreciated. I am sure it is no help to say this, but... this is the second time in two major updates that Windows 10 has completely screwed my displays. There is NOTHING unusual or "custom" or "special" about them. This is a standard windows build with an entirely generic 1080GTX and yet this is the second time this has screwed up...

Can anyone give me any form of assurance that this is not going to happen again please?

Thanks in advance for any help that anyone can offer.

Just a brief update to mention that the previous time this happened, which was March of this year, generated this thread:-

https://answers.microsoft.com/en-us/windows/forum/windows_10-update/updates-applied-on-march-13th-or-14th-causing/b4d64a38-94db-4818-9a44-3f205b34fb01?messageId=e3489f5b-e9e0-413b-a41d-c9ecafc28f0c

A close read will show that there are slight differences [for example today I see the missing monitor as "digital display", which wasn't the case in March...  but the symptoms are depressingly similar...

Hi Bunny. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

Let me assure you that you have been most thorough and already completed the first half of the steps I would have given for this. In addition to the following steps
If you want to report this to Microsoft use the Feedback Hub app in Start Menu where developers are tasked to process consumer feedback and may interact with you. But Microsoft will not even see it here because this is a tech forums where we are mostly volunteers trying to help solve your problems.

See here for troubleshooting monitors further including varying screen resolution between them:
https://www.kapilarya.com/fix-windows-10-doesnt...
https://www.digitaltrends.com/computing/how-to-...
https://www.addictivetips.com/windows-tips/diff...

Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

If nothing else works I would roll back Version 1803 in Settings>Update & Security>Recovery and then hide it until it matures using the Hide Updates Tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Thank you Greg, for the prompt and helpful response.

Unfortunately I won't have time to investigate further this evening, but I will aim to try tomorrow and will report back on the results.

Thank you

Greg,

Somewhat belated interim update...

I've been travelling with work and in light of the difficulties I'd experienced, I took my PC to a local specialist and asked them to check it over for me.

The first observation to report - something I should have considered trying for myself - is that both of the "Office" and "Gaming" builds appear to work if just one single monitor is connected to the PC. Unfortunately this does not help us diagnose the root of the issues, but it does indicate that the problem relates to aspects of multi-monitor support.

The second observation is that apparently both of my machines were running slightly older releases of nVidia drivers. Not particularly ancient - both about 3-4 months old.

We're going to bring both machines fully up to date with driver version and then see if that solves the problem. If it does, then it would suggest that the Windows 10 update "assumes" but does not check to confirm that the latest [or reasonably recent] drivers are in place.

I'm about to fly out again tomorrow, but should be back on or about Saturday 11th, so will hopefully have some news by then.

Thank you.

Greg,

Final update in "closure" of this ticket.

Updating both machines to the latest nVidia driver, whilst using just a single monitor to operate the PC, appears to have solved the problem.

This does not conclusively prove that having the nVidia driver at the latest release would have enabled this Windows update to work properly, but it certainly points the finger of suspicion and dependencies between the OS and GPU driver.

Thank you for your assistance; all working now...

Clive
