Q: in the overview of this monitor it states features of an IPS Panel and refresh rates of 165hz, but in the specs it says TN Panel and nothing about refresh rate. Please can you confirm if this monitor is IPS and what the refresh rate is.
Answer by Dan on 3rd December 2015
This monitor has a TN panel, I've removed the mention of IPS and 165Hz from the listing as this is the general description for the Predator line and not this specific model. -Danlevan
