We've never run into that one before. Would you be able to send over a debug log? Here are the steps:

• On the Troubleshooting tab, change the Logging drop-down to "Logging: Detailed"
• Restart DisplayFusion
• The next time it occurs, note the time so we'll know where to check in the log file
• Send us the DisplayFusion.log and DebugInfo.html files (can be found by clicking the Open Log button on the Troubleshooting tab)
• Disable debug logging after sending the log

To answer your question, Keith, yes it works fine when using Windows Screen Resolution. I only found the Monitor Profiles feature recently and have been disabling displays manually for a long time prior.

Going to a single display profile is fine, but when I choose my three monitor profile it seems the OS framerate drops 75%. It's noticeable in everything from the DisplayFusion wallpaper transitions to scrolling through webpages to typing text (watching it happen as I type this).

With a 3770k, two 770s in SLI, and two SSDs striped, I am used to a silky smooth Windows 7 desktop experience and can notice the performance drop immediately. I usually restart to get back to normal.

I'm using v6.1.2.

Please let me know if there is any more information I can provide. Thanks for taking the time to help out. ]]> https://www.displayfusion.com/Discussions/View/switching-monitor-profiles-causes-pc-lag/?ID=343b26f2-46dc-4b53-b6f7-68ef5243477a#2 Mon, 08 Sep 2014 17:51:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/switching-monitor-profiles-causes-pc-lag/?ID=343b26f2-46dc-4b53-b6f7-68ef5243477a#2 DisplayFusion That's strange! If you manually change the monitor settings using the Windows Screen Resolution settings, does everything work fine? ]]> https://www.displayfusion.com/Discussions/View/switching-monitor-profiles-causes-pc-lag/?ID=343b26f2-46dc-4b53-b6f7-68ef5243477a Sat, 06 Sep 2014 09:54:29 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/switching-monitor-profiles-causes-pc-lag/?ID=343b26f2-46dc-4b53-b6f7-68ef5243477a DisplayFusion Hi there,

Whenever I switch monitor profiles, my PC becomes quite slow in certain areas. When watching a video it will be choppy. When I type text there is some input lag. Many things feel a bit slower.

Even when I exit displayfusion the problem persists. Basically I have to log off windows and log back in to fix the problem (it doesn't even need a reboot, just a log off/log on). I checked the CPU usage and it's fine.

I am using version the pro version 5.1.1. Any help would be appreciated.

Thanks, ]]>
