Sorry yeah, that video perhaps isn't the clearest thing. It's a windows 10 PC, I logged in whilst the main monitor is connected to show it working, then connect the LG TV via HDMI and it black screens the monitor, and boots me out to the lock screen and won't let me back in.
Ok, somebody please explain what is going on. I am trying to connect my LG C9 to a windows 10 PC via HDMI When I plug it into the HDMI port on the graphics card, it locks windows on my main monitor and even entering the password just loops back to the lock screen. If I unplug my monitor and just have the TV connected it shows on the TV but also stays stuck in the lock screen loop. The TV is receiving signal as it displays the lock screen. It's something to do with Windows 10 not playing nice. The TV's firmware is up to date. The NVIDIA drivers are up to date. Please someone explain this before I lose my $h!t. Thank you PXL_20200929_215239578_(1).mp4
