I just purchased a USB C to Hdmi cable so I can connect our TCL Roku tv to my LG stylo 5. I have watch a zillion videos but nothing works. When I plug the hdmi cable into the Roku it does nothing. I even tried switching the input choice to smartphone and that didnt work either. I also powered off the TV and plugged the cable then repowered on and it still didnt find my phone device. Please Help
