XPS 8930, sleep/wake video driver bug with latest drivers

Obviously if the only change is the driver, then it must be a driver issue. The only thing I can think of trying is switching the primary and secondary monitors in the settings. Right click the Desktop, select Display settings, then click on the secondary monitor (#1 or *2), and then under Multiple displays check the box next to "Make this my main display". After switching the primary and secondary monitors your main display should now be connected via HDMI and your secondary display should be connected via DisplayPort.

If Vic's suggestion to switch primary and secondary monitors doesn't help and/or you're intent on having the "latest, but not so great video driver", you could try this:

Open the Windows Power options screen and identify the active Power plan. Click the link to change its settings and on next screen click link for Additional Options. On that screen, disable Hibernation, disable Hybrid Sleep,  and disable PCI Express Link State Management. Save the changes to the power plan and reboot.

Does that help when DP is still the primary monitor?

And it all goes back to the same old rule: If it ain't broke, don't break it! :BigSmile:

I have the same issues with a Vostro running onboard Intel UHD 630. It is a brand new machine and two rounds with technical support were fruitless. One person told me that since it is not a "hardware" issue, I cannot get free tech support even thought machine is less than a few weeks old. Also implied that my machine was sold as a single monitor setup, which make no sense to me. Dell did not provide the monitors either.

I went thru the same steps including changing which port drives the primary monitor. I also spent time with Intel who said there is a new driver, but not approved by Dell yet. Not sure if this fixes the issue.

Intel said there are a lot of people with this problem and Dell needs to address this with either their drivers or a discussion with Microsoft on possible changes with lastest Win 10 Pro updates.

I have an XPS 8930 using Intel-UHD-Graphics-Driver_H3PND_WIN_26.20.100.7263_A04.EXE so @m_gotts seemed to be using old drivers.  (CAVEATS: I also have an NVidia GTX 1660Ti add-in video card and I don't use dual monitors.)

@TangoC- Always include the exact PC model number in your posts!

Are you saying you don't have any add-in video card?  What version of BIOS is running? And have you checked the Support page for you exact model recently? At least some Vostros got driver updates this week...

Hi TangoC!

I have replied to you via private note.

@m_gotts- Did you make all the changes to the Power plan that I suggested in your original thread?

And if that doesn't help, you'll have to decide whether this monitor problem is more bothersome than having to look for BIOS and driver updates manually after disabling SupportAssist and/or Dell Update so you won't be force fed the bum Intel driver update again and again.

This is an update to my original post.  The problem is unresolved as of 12/18/19.  Drivers for the XPS-8930 with Intel UHD 630 video are the latest provided by Dell for the machine (as I and others have posted, Intel has newer drivers, but they won't install on a Dell machine).

With dual monitors, when the monitors go to sleep and then wake up later, only the one connected to the Displayport is initially detected on waking, not the one connected to HDMI.  So Win 10 moves all windows to the Displayport screen.  Then a second or so later the HDMI-connected monitor wakes up, looks and functions as normal.  But anything on it when it went to sleep has been moved to the monitor connected via displayport.

NOTE: this is *only* the monitors going to sleep, not the PC. There is no standby or hibernation involved because these machines are set to not sleep/standby/hibernate.

I've got three identical XPS 8930 machines with Dell monitors that all exhibit this behavior, but it started after a display driver update months ago and the problem persists now through several newer display drivers up to the latest versions.

I've sometimes been able to roll back the machines to the original driver that came with the computer by deleting the latest driver off the machine and rebooting.  But eventually (sometimes immediately) a newer driver is detected and installed.  The only "fix" for this is to then disable the Dell software updating service.  But that eliminates being informed of critical BIOS updates, etc, too, and would force me to manually look for updates at some interval.

It's idiotic that this is happening and extremely annoying to the users, who have just been beaten into submission and accept that this is how they have to work.   We've extended the monitor sleep interval to 30 min so that it only happens after lunch and overnight, but still.

The machines all have dual Dell P2217 monitors 

Problem: after the monitors are awakened from sleep (mouse wiggle, keyboard) and the user unlocks the machine with Ctrl-alt-del and their password, any windows that were open on the secondary display have been moved to the primary display.  This is consistent across all three machines, and just started happening after the new video drivers.

Any suggestions?

1. Instead, clean-install the Intel-UHD driver provided by Microsoft inside Windows-10. It should work perfectly fine for you.

2. Stop using HDMI ports. Use DisplayPort or DVI.

3. If you don't like those options ... wait for an Intel driver update. And then wait again for Dell to Validate it and upload it (since you apparently like to use those Dell drivers).
