Windows 10: HDMI LCD Not Detected after SLEEP mode

I have a windows 10 (1809, 17763.316) that the 2nd LCD works at boot time, but as soon as the PC goes into sleep mode the 2nd display never awakes. Only a reboot restores the 2nd display. It is only the HDMI port with this issue. The DisplayPort has no issues. I can reproduce it on other PCs with identical hardware. Some computer have device manager beeps of the LCD being found and then lost. This happens repeatedly and endlessly.


This PC is not in a domain it is a fresh install of Windows this week.


For the last 2 weeks I have tried everything I can think of and from the forums. LIKE...

Remove and reinstall drivers**** change bios power and suspend settings (e.g. S3, S5, etc).........


Any ideas on what to try next?


This seems limited to the Zotac Zbox MI547 with HDML and 1803 or higher. I cannot find any Zotac Zbox ID64, 67, or 68 with the issue and they are probably on 1703 or 09. That is my next task to review every PC with the issue and find similarities.


Here are the questions I know you'll ask about hardware and software.

Computer

Zotac Zbox MI547

Bios is latest version


Display Adapter Info:

Intel HD Graphics 620

25.20.100.6373

Latest from MS. Have even tried the direct from INTEL driver and it did not help.


Test Monitor with issue

DELL 1708FPt via DVI to HDMI converter

I can try other LCDs and ALL have the same issue. Even HDMI to HDMI.

Why exactly is ATi considered be better at HDMI?

I plug my HDMI cable into the card, then into my TV. Those are the steps that I have to do. All the steps you list make absolutely no sense to me.

 

sleep mode

Hi disgruntledWC,

There could be other settings on your computer that triggers your computer to go on sleep even though the sleep settings is set to never. To ensure that the sleep and display settings are properly set, I suggest that you look into the Advanced Power Settings.
Follow these steps:

• Open Control Panel and click Power Options.
• On your preferred plan, click Change plan settings.
• Click advanced power settings.
• Expand Sleep option, and make sure to set the following:

Sleep after : Never

Hibernate after : Never

5. Click Apply, then OK.

Please check also the screen saver option.

• Navigate to Settings > Personalization > Lock screen.
• Click Screen saver settings.
• Set your Screen saver to None.
• Click Apply, then OK.

Once done, please observe if your computer still goes to sleep mode after a few minutes of inactivity.

Looking forward to your reply.

Regards.
