Video issue between Apple TV 4K box and new samsung tv

Hello first post. I have an apple 4K TV box in my basement it was hooked up to an older Samsung 39" Tv 5 series and the apple tv worked great on it. I purchased a new bigger Samsung TV 43" Au8000 series and same cables same hook up the apple box stops playing I get a blank screen green lines at times the video is choppy when I get a blank screen it just freezes/pauses no sound either. I rebooted the Apple box same issue. It seems to happen on one app in pustular than on other which is odd it's been running flawless on everything. the app it acts up the wort on it motortrend+ and it stops. no issues with the old TV but this one Yes. Looking for idea's when it first booted up the TV said making adjustments for a better picture quality.
