HDTV Refresh Rate HOWTO: True 120Hz from PC to TV

Supported Displays: Several models including Vizio, Panasonic, etc. See comments.
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.
