I have 2 external monitors connected to a laptop workstation running Win 10 via a USB-C docking station with 1 DisplayPort and multiple HDMI outputs. If I boot the system with the docking station connected, DF NEVER detects the correct monitor configuration. The main problem is the horizontal LG UltraWide monitor, which DF detects at a resolution of 1920x1080, 60Hz, when the profile has it stored as 3440x1440, 60Hz. Once I manually load the profile, then DF detects properly, as shown in the 2nd attachment.

If I boot without the docking station connected, allowing DF to detect only the profile for the native laptop screen, then connect the USB docking station, DF properly sets the 3-monitor profile 95% of the time.

Any suggestions for resolving this detection issue? It prevents me from being able to automate application startups on the desired monitor using triggers at this time.

Before I try that let me ask a clarifying question. I'm definitely new at trying to automate display stuff, so I apologize if this is a ridiculous question.

Won't setting a trigger to load the profile when DF starts cause it to try to load that profile even when I'm booting stand-along laptop without the external monitors? DF currently gets it right when booting stand-alone. The problem seems to be with the inaccurate detection of the horizontal UltraWide monitor resolution.

I've thought of a kludge similar to something recommended in another thread. I could create a profile with the incorrect resolution settings that DF seems wont to detect, then set a trigger that when that profile is detected to switch to the other resolution.

Thanks, Owen. I've been traveling, but will get to this later today.

OK, Owen, here are the steps that I have tried.

• Created a profile to handle the incorrectly loading configuration. DF detects it just fine, but I don't see a trigger that I can use to switch to the correct profile once that incorrect one is detected.
• Deleted that incorrect profile so that it couldn't be detected (no way to disable a profile), set a trigger to load the desired profile upon DF start. Upon reboot, DF does not switch to that profile. It still detects the incorrect resolution on that UltraWide horizontal monitor.
• Set debug to L1 and rebooted. Boot time was ~16:00 CDT. Log attached.

Let me know if you have any further suggestions.

Thanks

One other possibly relevant piece of information is that the UltraWide horizontal monitor (designated as the primary) is connected to the dock via the DisplayPort output. The vertical monitor is connected to an HDMI output from the dock.

I apologize for the delay. I've been helping my son move 1100 miles away.

I've attached the output of the diagnostic that you requested, run while the 3 monitors were in the incorrect, lower resolution on M3, state.

Please let me know if you need additional information.
