Second monitor doesn't always display?

Hi Erik,

A secondary display may not resume after sleep due to some issues with the graphics driver or issue with the monitor's video cable. We suggest that you download and update the graphics driver by going to the laptop's manufacturer's support site.

You may also try to replace the monitor's video cable and see if resolves the issue. As we checked the specifications of your monitor, it turns out that it has a DVI-D and VGA ports. You may check your monitor's manual or visit the manufacturer's support
site to get more information.

Let us how it goes after performing the suggested troubleshooting steps.

Windows 2019: Some Monitors do not resume display after display power off timeout time

Hi,

We are getting this issue from our customers-

Monitors:

IBM TFT LCD T117

AOC 931Sn

BENQ GL2250-T

Server systems

CPU Skylake/Caskadelake

Matrox vga display onboard

Windows: Server 2019 version 1809 (OS build 17763.107)

Resolution: 1024x768, 1440x900, 1920x1080

Windows: Server 2016, 2012, 2008 or any Linux distribution works fine

Steps:

1) Fresh install Windows: Server 2019 version 1809 (OS build 17763.107)
2) Install Matrox vga display driver latest one and reboot the server
3) Windows booted and go to device manager and check the display driver loaded
4) Set display resolution 1024x768
5) Turn off the monitor and turn on
6) Monitor displays properly
7) Start > Settings > System > Power & sleep When plugged in, turn off after 10min (default)
8) This value can be changed to 1 or 2mins.
9) Keep the system idle for more than the timeout value (1 min 2 min or default 10min)
10) Now display goes to blank state and LED of the monitor is amber
11) Now press any key or move the mouse
12) LED of the monitor becomes green but LCD remains blank
13) Power off the monitor and power on, display does not come
14) Display in BMC KVM works fine all the time
15) From KVM change the Resolution to 800x600.
16) Monitor resumes the display

We have used same steps with Windows 2016 and Windows 2012. The issue does not happen there. This issue does not depend on servers or desktops but it follows with these monitors and OS Windows 2019.

Please help and suggest.

-Thanks
