LCD's are standard 60Hz refresh rate. But you can increase it to 75Hz to get better image quality in games. What I wonder is if the increase will have a negative impact on the monitors input lag? If it takes e.g. 40ms for the image to show up at 60Hz will it now take e.g. 70ms? Besides DVI is cut at 60Hz. Anything above 60Hz it have to send the image twice like 50Hz+25Hz. What the standard of the DVI for 60Hz does it send the image at 60Hz or does it go by 30Hz+30Hz?
