explain your issue with better English, thanks
I'm also having this issue, but just directly connecting to my LG TV. its a webOS tv from years ago that's discontinued, I've factory reset it a couple times already and tried ethernet and Wi-Fi but every time I connect windows says "Connected" and then windows will freeze but I can still move my mouse, it unfreezes after a few seconds then it immediately says "Disconnected." a few seconds later. but my phone can cast to my PC fine but not my TV, so it's not a router port issue or anything like that. I've tried 2GHz and 5.8GHz and neither of them work. same result. started happening randomly a while ago, the only reason I need to do this is because my VR headset requires a HDMI port and so does my monitor. the only problem is I don't have 2, I only have one HDMI port on my GPU, while my Ryzen 5 3600 doesn't have onboard graphics so I can't just connect it directly to the motherboard. if anyone finds a fix please tell me.
