Question Having Issues w/ Dummy Plug

[BigDaddyDingDong]

I have had my Legion RTX 4070 83DH connected to my network for almost a year now, using a dummy plug to remote into it with Moonlight/Sunshine and play games throughout my house on my TVs and tablets. I moved my laptop over to a living room TV and replaced the dummy plug, and connected it directly into the TV via HDMI. Now, when I plug the dummy plug into the Legion laptop, it doesn't allow me to use it. I go to select it in the system/display windows option for multiple displays, and it deselects it after I try to apply. In my Nvidia control panel, and the same issue. I get no display resolution or display orientation options for the dummy plug.

Sounds like it's possibly just caching old EDID's from where you moved things around. Perhaps try an EDID Reset.
