As I understand it, LCD TV's produced for the New Zealand market which feature an internal 100hz refresh rate accomplish this by generating "fake" or "artificial" intermediate frames, rather than actually accepting a 100hz source, such as could be provided by a 100hz capable videocard in a PC.
I also believe that we in New Zealand have 100hz rather than 120hz capable LCD TVs due to our using the PAL video format, which refreshes at 50z, rather than NTSC at 60hz.
This then would make me assume that for the 100hz "fake frame" technique to function, the source would need to be a common multiple of 100, which leads me to my main question - what happens when a 100hz LCD TV is connected to a PC providing a 60hz signal?
Since 60hz is no longer a common multiple of 100, do moving images on a 100hz LCD TV connected to a PC stil possess the smoothness associated with 100hz TVs?
Also, if you were playing content on your PC at a strange frame rate, say for example a PC videogame and getting 32fps, how would the 100hz "fake frame" technique deal with this? Would it generate a huge number of intermediate frames to cope?
As you can see I'm quite confused and I'm not even gonna bother putting such a question to a salesman in a shop, as he would be clueless.
