“Why can't my tv pick up a signal from my mac laptop when I plug the HDMI in? No signal (is it on)... It works on other tv's I have so it's not the hdmi, and the port I have it plugged in picks up signal when I plugged my PS4 into that slot. Any solutions?”

Make sure you labtop is set to project signal out of your video card. It's plug and play for the tv but you have the tell your pc to turn on the hdmi port.
