I just recently bought the Optix g24c and i just received it today and on the website that i bought it on it said it was 1ms MPRT and i tested it on blur busters and it said i have a 6.4ms response rate so im just curious about what that means exactly and why it is 6.4 on that website but advertised as 1ms. And what is the difference between MPRT and normal response rate.
