Creates interference/ static in picture

Does what its supposed to do but creates static. Tried several hdmi cables and the device still produces interference. Well built though, the metal casing is solid and it didnt run too hot. I will also mention i was outputting with the 3.5mm audio port. And i had to crank the speakers higher to get the same level of sound from other inputs. Im not sure if that means its weaker but it this helps someone else thats always great.
