i currently run my VG278HE monitor at 110Hz at 120-144 my movies in WMP will start to lagg and shake which is almost sickening to watch but is fine at 110 also it doesnt matter what i set the refresh to i seem to experience alot of occasional tearing i hear Nvidia G-sync can fix this but is that the only way? never had a problem on my old HP2011X monitor...but that was a pos compared to this one
