Hi. I have a LG Smart Tv and I want to project movies on the tv. I have a HDMI cable but it says "no signal" . The tv does recognize the PC when I plug the cable in it, it even pops up the button to change to the right HDMI "channel", but it still says no signal.
I tried it on a different LG tv (not a smart tv, just a normal one) and the same thing happened, it just says "no signal".
My pc is a hp elitebook so everything should be pretty new and up to date.
Can anyone help? What's the problem?
