I bought the 32 inch roku tcl 3 series. I did the set up all that and everytime i get on xbox live it lags to the point my player isnt even walking hes studer steping. I cant even play. Idk if i should return the tv or not. And yes i pute game mode on that dont help at all . Ive been googling going through forums you tube videos etc trying to find problem but cant.. Hopefully someone can tell me something before i return the tv. Its stressful. And my internet is just fine.
