I recently ordered and received the Asus vg258qr which was advertised as a 165hz 0.5ms response time but I got the box and it said 1ms response time. Does this mean I got the wrong monitor or is there something seperate I have to do to get it 0.5ms. I am confused because I watched someone unbox the VG278QR and their box said 0.5ms so what's different or wrong with mine? Any help is greatly appreciated. 
Edit: I just watched someone with the same monitor as mine and their box said 0.5ms response time. Someone help
