A:AnswerNot sure if this is a question, but do you have a 4K cord and is your box or whatever your using in 4K resolution I bought mine three weeks ago and I have no issues.
A:Answeryour home wifi network is weak or too slow to have unabated streaming. If its the signal use a hard line from your internet modem/router into the tv. if that doesn't solve it upgrade your home internet speeds.
A:AnswerYou probably can't. Again, this TV has TERRIBLE input lag, and there are no adjustments on the TV that completely remove it.
Take it back, swap it for a same-priced 1080p television. Right now, cheap 4K is going to be like this.
A:AnswerNO. This TV has TERRIBLE input lag. Gaming is awful on it, even in "game" mode. I highly recommend anyone who wants to play video games look to a 1080p television in this price range, or spend at least twice as much if you need 4K. Low-priced 4K panels are awful for games.
A:AnswerYou don't ever want to use the composite, red, white and yellow cables unless you hook up a vcr.....those are analog a/v cables. Quality of this TV I would recommend HDMI cables if possible. Red green and blue are digital (low end) video and the red and white (composite) would be audio if you want cheap.
A:AnswerNo. Calling this a "smart" TV is a bit of a stretch. There are a few built-in apps (Netflix, YouTube, AccuWeather) but THAT'S IT. No way to add anything else that I've found.
