While this monitor for the most part ran well at 240hz with Motion Blur Reduction turned on, there would be black artifacts from the monitor that would come up from time to time, or microstuttering, and so forth. It seemed that the frametimes could not match up with the display output which would cause the stuttering to occur sporadically.
