That's it. No use arguing that LCD monitors have a "fake" hz cap, or that ghosting relates to high response times, since those are the properties of most / all LCD monitors.
Nope. Already explained what are they capable of doing. LCD manufacturers want to ensure that their monitors function well in all situations, particularly since they often overstate response times in the published specifications. So typically they set the maximum supported refresh rates on their monitors such that they are relatively conservative and can meet the challenge of refreshing the entire screen as often as required in any situation without any noticeable ghosting.
LCDs work on the basis of receiving new frames of information from a graphics card's frame buffer like a CRT would: eg during the VBI. So when VSync is disabled the graphics card will sometimes race ahead and when the LCD monitor indicates it is ready for a new frame during the blanking interval, the graphics card may provide a partially new frame overlapping an older one, just like it would for a CRT. An LCD monitor will then display this just the same way a CRT monitor would, resulting in visible tearing. At 10ms it can refresh it 100 times per second but its cap to 60 wheres the tearing you would see? Fast action games do not run faster than 50 or 60 fps. Look at the Xbox its capped at 30 to 35 fps. People think 60hz is bad because of Vsync dropping their frame rates in half without realizing theres tripple buffering to get it up to just under the refresh rate. Your telling me at 60hz a lcd is too slow but at 120hz it aint?
