Katsuo said in What do we think about this monitor?:
ShiftySatchmo The only thing where Samsung is better is the response time. 1ms compared to 5ms on ViewSonic. But in my opinion, response time is completely useless if you aren’t a professional CSGO player XD
Response time impacts ghosting and under 8ms is fine. Input lag is the thing you want low low low. Neither is a problem to worry about on a decent monitor these days.
