Hello Trippi93
My name is Elizabeth. I will be happy to help you today.
With none of the 3 TVs could you connect it? Do you use the same HDMI cable in all of them? If it is the same cable, try again with a new cable.
Turn off the computer, then disconnect the HDMI cable, turn on and connect the HDMI cable before logging in, when you enter your password (If configured this way), press the keys at the same time Windows (Logo) + P to observe the different options to project to your TV and see if you recognize it.
