. I’m assuming this is the HDMI cable, or the laptop port itself. But anyway: My laptop is always hooked to my tv. No issues, but for some reason there is the multi-colored bar at the bottom of my tv. The laptop screen doesn’t have it. And I put the tv onto other settings and the bar isn’t there, so it’s not the tv. I also tried to put the cable into another HDMI port on my television. So, any ideas?
