I connected my TV to my laptop using an hdmi cable. I found and set it as an additional monitor but the TV would not display anything besides the lg no signal logo. After this i accidentally set my laptop to display only out of monitor 2. My TV is set as monitor 2 and will still display only the lg logo. If i unplug the cable and restart my computer it goes back to the laptop screen. And for some reason it will only let me find the TV as a device while restarting my laptop, and when i restart my laptop it automatically goes back to the setting of only using monitor 2 and i cannot see anything. Can someone please help me figure out how to fix this?
