Higher success rate for Active 3D HDTV’s (the type that use electronic shutter glasses).



Some HDTVs have an undocumented ability to accept 120Hz from a PC.
Many TV’s do 120Hz internally for a different purpose (e.g. motion interpolation, active 3D). These TV’s support the dot clocks necessary for 120Hz because active shutter glasses 3D @ 60Hz (frame-sequential) use a similar dot clock frequency as 2D @ 120Hz.

It is important to note not all televisions can be forced to accept native 120Hz via external connections through refresh rate overclocking. A successful HDTV overclock to 120 Hz will result in 50% less motion blur compared to 60 Hz. Some models that do 120Hz internally (e.g. Motionflow, 3D) can also accept 120Hz externally.
