Greetings,
I’ve got a conundrum I’m hoping somebody can help with.
I built an A/V setup in my classroom centered around a PC (my build: Windows 10 Pro w/ a GTX 750 GPU), a Yamaha RX-A760, and an Epson EX 9200 projector. The computer sends a signal via HDMI to the receiver, which then sends it via HDMI to the projector. A *separate* hdmi cable directly connects the computer to the 24” Dell IPS desk monitor.
The problem: Suddenly, out of the blue, turning off either the Yamaha receiver or the Epson projector turns off the desktop monitor too.
It never use to work like that . . . I’d work at my desk with the projector off, and the monitor worked fine. I had Windows 10 and the nVidia software set to see the monitor as the primary, and clone it to the projector. Then one day, 4th period, something changed. I turned off the projector, - **poof** - no monitor signal either.
Troubleshooting:
Any suggestions or help would be greatly appreciated!

Troubleshooting:
- I checked the Graphics settings. All is correct – monitor is primary, cloned to projector
- I did a clean reinstall of the Graphics Drivers, using DDU uninstaller to be sure I got it all
- I changed cables, and which ports they were plugged into on the GPU
- I made sure CEC HDMI control is OFF on the Yamaha Receiver
Any suggestions or help would be greatly appreciated!
