My screen suddenly comes to life unexpectedly.
My screen suddenly comes to life unexpectedly.
I installed the driver yet nothing changed. The unusual thing is that when I put the computer to sleep, it doesn’t wake up automatically—it stays still, even the monitor. However, if I disable sleep or hibernation, the monitor keeps triggering wake-up issues, sometimes every minute and other times after a few minutes. When I’m using the headset, I can hear its plug/unplug sounds, but I’m not sure if that’s just the monitor being removed and then reattached. I attempted to run a USB log view, but it returned nothing.
The issue seems to be the computer staying on standby and shutting off the display. It's unclear exactly what triggers the screen to activate, possibly due to the mouse or a slight air movement.
The most irritating feature in Windows 10 is the troublesome window management. Checking the command prompt for "powercfg last wake" might reveal what controls are active. If not, running that command could clarify who’s in charge.
It asks for clarification about a command's purpose. It doesn't perform magic fixes but usually provides information or instructions.
Last wake doesn't seem to work properly. I attempted a similar fix and it caused issues. Once I changed the cable, the device became stuck in its position and had to be removed. It's unclear if any signal is being sent from inside. Since it's not currently in use, it's using HDMI until my graphics card arrives. The problem also occurred on port 2 of the monitor while I was using it, but port 1 remained functional. When I put the computer to sleep, the monitor didn't stay awake, suggesting it's receiving a signal. It's odd that this happens during the first boot after a Windows reinstall, even when all USB devices are disconnected. After installing drivers, I get alerts whenever the HDR monitor is detected, as if it's been connected and disconnected. I'm considering testing the TV on a laptop—it doesn't wake up, which points to a possible system or driver issue. Perhaps the BIOS version or chipset drivers are causing the problem. I've tried two different versions of both, but it persists. EDIT: I had to test the monitor on a laptop; it didn't wake up, so something in my new setup must be wrong. Maybe the BIOS or chipset drivers are interfering. EDIT2: Booted with USB into Ubuntu—display stays in standby only within Windows. Likely a driver problem, given the safe mode behavior too.}
Hi Cissamannen, I've encountered the same issue exactly. Have you discovered what's causing it? It's unclear whether it's hardware or software-related. If you want to investigate further, in the Windows Event Viewer, look at [Windows Log] and [System]. You'll see an event with ID 566 that matches the exact time the monitor wakes up and turns off. The "Reason Unknown" event for the monitor is also puzzling. Perhaps another reason could provide more insight. Let me know if you've resolved it or how it went.
I'm facing the same problem. All other wake-up devices are turned off except my mouse. I own a 9800X3D and an x870e Nova. It seems there might be a chipset or BIOS issue causing this, but nothing else fits. @Cissamannen, if you can solve it, please let me know.
Review the settings in your Network Adapter Advanced section. Look for options like Wake on MAC Address, Wake on Pattern Match, Wake on LAN, and any other features that could be contributing to the issue. Also check the Power Management tab to see if "Allow the computer to turn off to save power" is enabled. If it is, the option "Allow this device to wake the computer" should appear. Let me know if you need further help. Edited March 6, 2025 by Superxdave
I actually got this to stop somehow. Even when everything was disconnected. It looks like the keyboard was the problem due to its connectivity. Before I added the antenna, I used a USB dongle to connect it. When both the Wi-Fi/BT antenna were installed and the dongle moved closer to the front of the case, the issue disappeared. Now it occasionally wakes up for a second or two but then sleeps normally until you move the mouse again. It seems like a combined problem—either the Bluetooth was trying to connect or the dongle was using 2.4GHz, depending on which was active at the time.
