Ok - I have come across an old 17" CompUSA monitor (CRT) from way back in the day. I say well over 4 years old, but it is still chuggin with no signs of wear at all. Now, the question - is there an app/method I can use to determine what the maximum refresh rate allowed on this monitor would be. Unfortunately, there is no tag/SN on the monitor, so I would venture that the only other way would be through a stand-alone app. Any thoughts?
