TwinView Refresh Rates
One of the most frequest questions that we get asked is "What refresh rates can my second monitor generate with one of your TwinView cards?"
In order to help clear up any misunderstands, we wanted to let everyone know that the TwinView cards (that support 2 monitors) do have their own RAMDAC for the second monitor. The table listed here shows the possible resolution and refresh rates that are available for the second monitor:
