I bought an LG monitor and its giving me a headace due to its low Refresh rate. Its 23inch and its set at 75Herts as it wont go higher, i have all the latest drivers for the monitor and the graphics card (EAH5770 with the huge heatsink). Did I buy a lemon or is there something wrong with me?, I can almost see the screen refreshing and at 60 herts my brain nearly passes out. My old monitor was set at 75 herts and I could use it all day with no problems. What am I doing wrong? :cry:
