Windows becomes unresponsive when the AV receiver is activated alongside the new RTX 3080 graphics card.
Hello everyone. I finally acquired a new graphics card, an ASUS TUF RTX 3080 (LHR). Everything functions properly until I connect my AV receiver (Onkyo TX-RZ730). Two monitors are linked—LG Ultra Wide (3440x1440 at 60Hz) via DisplayPort HT225HPB (1920x1080 at 60Hz)—and the receiver is hooked up to a 4K projector. The AV receiver connects to the projector, which is usually off during PC use. When I switch it on, everything operates smoothly except for freezing issues. Audio stops instantly, and I need to power cycle both the receiver and PC. The connection is through HDMI. I experimented with different cables and ports, even tried a DP-to-HDMI adapter, but nothing changed once the receiver powers up—only a frozen screen appears. If I power on the receiver before starting the PC, I see a loading screen, then it turns black completely, hiding the lock screen. When I turn on the projector first and then the receiver, everything works perfectly: resolution, sound, and picture function correctly. However, if the projector is switched off while the receiver stays on, the display remains frozen. With my previous card (GTX 950), it worked fine. If I power on the receiver without the projector, windows interpret it as a 1080p monitor, allowing me to use the HDMI output for audio. I’m using Windows 11 and installed graphics drivers without the “game ready” utility. My ROG Strix X570-F gaming card runs the latest BIOS. The CPU is an AMD Ryzen 9 3900X. I have no idea what else to try, and I’d really appreciate any advice on resolving this. Thanks in advance. Fabe1999
