TV connected via HDMI triggers Windows to refresh or reset the screen unpredictably.
TV connected via HDMI triggers Windows to refresh or reset the screen unpredictably.
I've noticed this problem after my system was installed. I've been dealing with it until recently when I realized the HDMI connection was the root cause. The issue occurs when my TV stays connected to my PC and then suddenly refreshes or resets its monitors, just like when you plug in or remove a display. It might happen a few times within a short period or once every eight hours—it's quite unpredictable. I searched for similar reports but didn't find anything that matches exactly. Eventually, I discovered EDID emulators and think they could help. I'm still unsure and would appreciate any clarification or advice. Since this isn't a crash and seems unrelated to software, I'm leaving out some details from the guidelines. Please let me know if you have more information to add.
In the TV menu, is there a way to turn on HDMI-CEC? This allows managing power switches for devices using the same cable. It doesn't impact your PC but may cause issues like the glitches you're seeing.
I also have that feature, but it wasn't turned on. I'll attempt to activate it and check if the reset happens during the day.
In the past few days I believe it may have restarted once, though it seems to have stayed stable overall. Besides turning on HDMI-CEC, there was a significant WebOS update I applied. The only possible reset happened shortly after the upgrade, which could explain it. Marking this as resolved now. Appreciate your help!
