Turned it off and seemingly no more issues. I'll post again in a few days if it comes up again. ]]> https://www.displayfusion.com/Discussions/View/screen-turns-on-and-off-after-using-displayfusion-to-switch-monitor-profiles-with-hdr-on/?ID=018f8c75-b29f-7466-9c5f-2f1f0aff54e4 Sat, 18 May 2024 16:07:55 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/screen-turns-on-and-off-after-using-displayfusion-to-switch-monitor-profiles-with-hdr-on/?ID=018f8c75-b29f-7466-9c5f-2f1f0aff54e4 DisplayFusion Hi!

I've been using DisplayFusion over the last few months. It's been super useful to switch from my multi-monitor work setup to TV gaming on my couch. However, a recent issue with HDR is making me go crazy.

Basically, if I turn on my PC on the dual monitor setup and use HDR everything works well.

If I then move onto the big TV to game with HDR on, that works well too. I set up a trigger function to open Steam Big Picture mode and that works as intended.

However, the moment I go back to the two monitors by using the assigned key combination everything goes wrong and my the monitor where I have HDR on will lose signal again and again on only one of the monitors as if the OS was trying to find the screen again. Also, if I manually switch things around without DisplayFusion the issue doesn't occur at all, so I'm suspecting it has something to do with the software.

This happens regardless of the refresh rate that I use for the impacted monitor, and will occur even if I turn on HDR on the other monitor only and keep the impacted monitor in SDR. This also happens consistently with two different NVIDIA GPUs so I doubt it's hardware-related and the impacted monitor otherwise works perfectly so I doubt that's the issue either.

Also, the computer will stick to this behavior until I restart or switch cables to the other GPU after the first time I've switched to the TV and back, no matter how many times I turn HDR on and off.

Any ideas as to what may be happening? DisplayFusion has made switching to my TV the simplest thing ever and I don't really want to stop using it ]]>
