I have a PS4 Slim and I play on a Phillips TV. It is possible that frames are dropped when playing on a television. My friends advised me to buy a monitor, would it be a wrong decision?
It doesn't make a difference, stick with the TV. You should only activate the gaming mode there, this reduces the input lag.
How can I activate gaming mode? My television is a bit older
In the settings. Maybe he doesn't either. The newer televisions have picture enhancers, but these lead to higher input lag. If yours doesn't have one, you don't need to adjust anything.
