Your setup is causing the issue because Windows is automatically switching the primary monitor to the TV when you change displays. To fix this, you’ll need to adjust how Windows handles display switching. Try using a third-party software like DisplayFusion or a custom script to manage the switch, or configure your display settings so Windows doesn’t auto-reassign the primary monitor. If you want a permanent solution, consider changing the display driver or using a dedicated external monitor.
Upon startup, the display that appears first is determined by the boot order, and the corresponding Windows login initiates the session.
Not sure, perhaps it just switches to a default setting—swapping the GPU cables might assist. In any case, why not keep it extended and move the video player over to the TV?
It's often discussed as a configuration issue. Some suggest it might be related to the TV being prioritized during installation, similar to how Windows once wrote system files to a secondary drive when a secondary device was connected. It's been a while since that happened, making it hard to recall exactly what occurred. I'm curious if you'd like my take before deciding to reinstall Windows.
You're seeing multiple display solutions like DisplayFusion, Actual Multiple Monitors, and MultiMon. That's common when integrating different technologies.
