extended display not working

Hello, im trying to use my tv as my second monitor, but it only works on duplicated image mode (mirror). When i press windows + P and select extended, my tv says to check the power source. Since it works with mirror, I dont think it is a problem with the cable. On windows it was working ok. Any toughts? Thanks

Well, forget it. Im going back to windows. I have no time to make a phd just to use my computer. Linux need an other decade to be usable. Even to change a theme is a shore.
