I've decided on buying the BenQ RL2455HM but was wondering if I'd see a noticeable difference from the monitor I currently have. The BenQ monitor has a 1ms response time, 12000000:1. Not to familiar with what these mean, but the monitor I currently have has a 5ms response time and 700:1. I do still plan on using my current monitor as a second monitor and have the BenQ one to be my primary monitor. Will there be a significant difference in the two monitors? I plan on using it for mostly gaming.
