If you do run into it again, please let us know.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#8 Fri, 27 Apr 2018 21:52:35 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#8 DisplayFusion I have not identified a CPU spike attributed to DisplayFusion since the update to 9.2 (beta 1).

I think that resolved the issue.

Thanks for your help! ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#7 Fri, 27 Apr 2018 18:42:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#7 DisplayFusion Sounds good, thanks! Does it still hang briefly as well? Or is it just showing a short CPU spike in Task Manager occassionally now? ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#6 Wed, 25 Apr 2018 18:41:02 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#6 DisplayFusion I've installed 9.2 (beta 1).

The CPU spike only happens intermittently, but so far, so good.

I included the log from after the update to 9.2 (beta 1)

I'll report back if I see the behavior.

Thank you again, ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#5 Wed, 25 Apr 2018 15:41:54 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#5 DisplayFusion Hi Keith,

Thank you for your assistance.

I am obtaining a temp local admin password to install v9.2, Beta 1.

I'll report back with an update when I've installed the beta. ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#4 Tue, 17 Apr 2018 18:41:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#4 DisplayFusion Ok, there's not much information we can pull from 9.1 to troubleshoot this further. If you can update to 9.2 Beta 1, that would be great. We've made a few changes to hopefully fix this issue in 9.2 Beta 1. ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#3 Mon, 16 Apr 2018 21:05:49 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#3 DisplayFusion Hi Keith,

I do not have local admin on my laptop, so uninstalling and reinstalling is not a good solution for me.

I just experienced the issue where the CPU usage pegged at 100%, with 93% of that being DisplayFusion.

I attached a screenshot of Windows task manager and another log file.

I noted that only one of the three displays was completely unresponsive.

What I mean by this is that if I clicked an application icon on the taskbar of that monitor, the focus didn't change to that application. I eventually got a Windows busy indicator (hourglass), but if I clicked an application icon on the other 2 displays, it changed the focus to that window.

The problem display is display #3, which is not the main display, but an extend to display.

It is one of two identical Dell 2317H displays, being used in conjunction with the laptop display.

Display #2, another Dell 2317H, is the main display. ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#2 Wed, 11 Apr 2018 17:28:49 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4#2 DisplayFusion Could you try rolling back to 8.1.2 and let me know if you still see this issue?

Thanks! ]]> https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4 Tue, 10 Apr 2018 18:04:06 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/displayfusion-spiking-cpu-to-100/?ID=9c4383fb-eb88-42fd-ae8b-347c5d30b4c4 DisplayFusion Recently I have regular occurrences of my system hanging for 20 - 40 seconds, or so.

I just recently identified that when this occurs, Windows Task Manager shows the CPU pegged at 100% and DisplayFusion is a large percentage of the total.

I noted that when the spike clears, there is still a significant percentage of current utilization attributed to DisplayFusion.

I am attaching the export of the Troubleshooting tab, but unfortunately, this is not from when the spike occurred, but some time afterwards.

This is DisplayFusion Pro 9.1, Build Date: Nov 14, 2017 20:12 on Windows 7 Enterprise.

My user is not an admin on the computer, but DisplayFusion has been working well for the past year that I've had this laptop.

The laptop is docked, open and has 2 additional displays connected, for 3 total.

Thank you,

Dave ]]>
