So I have scoured the web and I cant seem to find an answer on how to do this. I am running an ati 5850 with three lg Ips236v's. I have found a few people who have said they have managed 75hz on this monitor no problem so I wanted to try. I simple cannot figure out how to force the monitor to the higher refresh rate. I have tried rivatuner, ati tray tool, and a few other methods but non seem to work. So if anyone could help me out I would greatly appreciate it
