It is a 1080p 144hz monitor, connected by Display Port, and I observe the same 5-ish seconds display and disconnect on various occasions: 1. When using an application in full-screen - This includes full-screen video games, full-screen YouTube videos, spectacle's screen capture mode and even viewing an image from telegram client in enlarged view. Any app that is not full-screen works fine in this case. 2. When pc stays on idle and screen shuts down - This is not consistent but sometimes happens. In this case, even when there are no full-screen applications the display keeps disconnecting. This makes it impossible to use the pc at all. Shutting down the screen is no help. I have a solid fix that works every time. For #1, follow the steps: 1. Open Display Configuration (hitting Super key breaks the full-screen render, so display comes back I think) 2. Set refresh rate to 59.95 Hz (others might work too i didn't test) 3. Wait for the Apply/Revert changes pop-up and choose revert This fixes the issue and apps can be used in fullscreen without issues; until it is broken again, by whatever reason. It can break during the same session too. For #2, I didn't event manage to open Display Configuration for the first few occurrences because in that case, the display never comes back on. But after some trials, I noticed that moving the mouse cursor fast (that makes the cursor go BIG) fixes the issue as long as it stays big. Display just comes back. You can apply the same steps for case#1 while wiggling the mouse! It fixes the issue. Not sure if this would help but, I made system updates at: 2025.11.06 2025.11.02 The issue was started before 2025.11.02, I don't remember when I did my last update before that, but it should be the weekend prior. Probably 2025.10.26. The issue I mentioned at #2 only started after my last update.
