A:AnswerI do not have this TV but I did buy the 55 inch sharp tv from bestbuy. Same thing was happening to mine. So I bought a component wire instead of an HDMI and I have zero issues now. My son's 55 inch 4k ultra lg also was doing it, he went and bought a higher refresh rate HDMI cable made for 4k tvs . Hope this helped. Oh not creeping around lol was thinking of buying this tv :)
