Windows 10: After Windows 10 1709 Update Monitor Blank after Power Off then On

Good Day Everyone,

It has been a long time since I posted here, mostly due to major life changes, loss of jobs, etc. I wish I could be more active.

In any case. The issue I am having is 1 of my 3 media machines is not working correctly and I cannot figure out what changed. I have 3 Dell 790's (yes I know they are old but they do the job) connected via DisplayPort to HDMI to TVs. All have worked perfectly for the last 3 years and for the last 2 years on Windows 10. 2 days ago I took the 1709 update for all of them, they are on 365x24x7 and are in some state of use throughout the day. All 3 machines took the update fine, all machines work very well. Except, 1 of the machines, when I turn off the TV and come back later the screen is blank, blank like when you are logging into Windows 10 on a 2 monitor system and the second monitor is blank. The machine is running, and everything is working, just the video is gone. I have done a bunch of testing and the machine is working, if I pause a video, turn off the TV and then turn it back on the screen is blank but pressing a key the video starts playing and you can hear the sound. The computer is fine, it is working, just no video. I have tried a bunch of tips in the forum but nothing has worked. BTW swapped the TV just incase, still has the same problem. I have done all the other normal things, scan for viruses, disk corruption, registry issues, etc.

All machines are:

Windows 10 Pro 1709 16299.125
Intel i5-4590T 2Ghz
8GB RAM
Built-in Intel HD GPU 4600
250GB non-SSD Hard Drive

No downloaded drivers all are from Microsoft ONLY. The only software that is install is VLC, everything else is Microsoft. The machines are only used for NextFlix, YouTube, Internet Browsing (email, etc.), and Playing Music or Videos in VLC. The account used to access them is a standard user, with reduced rights to avoid Internet Infections, or children installing software etc.

Anyone have any idea?

When after shutdown should power strip be turned off?

I notice that on Windows 10, unlike Windows 7, after starting Shutdown the monitor very quickly goes dark. However, after this there is another 20 to 30 second wait before the power light on the computer case goes off. Do I have to wait until this power
light on the computer case goes off before I can safely turn off the power strip which supplies power to the computer, monitor, and other peripherals? Or can I safely turn off the power strip as soon as the monitor goes blank?

 

Monitor turns off then on, off then on.

Hi,

Thank you for responding.

I suggest you to try the below troubleshooting steps and check if it helps.

Method 1: Run Power troubleshooter and restore the power plans to default


Step 1: I suggest you to run power troubleshooter to check if there is any corruption in the power plan settings and check if it helps.

• 
  Type troubleshooting in the search box on taskbar and click on it in results.
  
• 
  Click View all and then click
  Power.
  
• 
  Click Next and follow on-screen instructions.
  

If the issue persists,

Step 2: Reset and restore the power plans to default:

• Right-click on Start button
  and click on Command Prompt (Admin).
• In the command prompt, type powercfg –restoredefaultschemes
  and hit Enter.
• Exit command prompt.

Note: This would reset the power plan settings to default. Any customized power plans are would be removed.

Method 2: I suggest you to perform a
Clean boot to
check if any third party application is causing the issue, as clean boot helps in eliminating software conflicts.

Disclaimer: Putting your system in
Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

How to perform a clean boot in Windows

(Applies to Windows 10 as well)

Note: After troubleshooting, refer to the section “How to reset the computer to start as usual after troubleshooting with clean boot” to return the computer to a
Normal startup mode.

Hope it helps. Reply to the post if the issue still persists for further assistance,

2) Are you able to install computer manufacturer or component manufacturer drivers?

Post the computer specs in the 'My Computer section will enable viewers to see the information without having to scroll through pages of posts.

 

I will post as soon as I get out of work.

Computer Specs: I thought of that, that is why I put the computer specs in the original post on the first page, no scrolling needed. *Smile

 

Hi, @WindowsStar. The reason zbook asked for the specs to be put in your profile, is so they will follow you wherever you post, now and the future. Not everyone will be aware that they need to look at the first post on this thread to find them. The links for instructions are in post #2. It really is helpful to have them readily available at any time. It's speeds up replies to your questions. Thanks.

 

OK, everyone, I am stuck at work. This happens sometimes. I may not be home for 36 to 72 hours. -WS
