- The PC is always-on, and turns off the TV after a timeout. When I turn the TV back on, the PC make a "device connected" and then a "device disconnected" sound.
- When I switch the TV to another HDMI input, the PC continuously makes "device connected" / "device disconnected" sounds through its speaker (connected to speaker port, not through HDMI). I have to mute the PC to avoid the sounds.
- The TV shows up as
Generic PnP monitorin device manager. Previous PC showed it as "LG TV".
- Entech MonInfo shows
Model name: LG TV, so the ID signal does reach the PC. It also shows
Windows description: Generic PnP Monitor.
This TV didn't have this issue with my previous PC, which had an AMD Radeon HD4650, also connected via HDMI.
- How can I determine what device is being connected/disconnected? I looked around in event viewer, but didn't find anything.
- How can I avoid these sounds?
Update: I got a supposed BIOS update from eGlobal. But it was the exact same version I already had - GBDW 1.08, 8/29/2015 - and of course didn't change anything.
