The bleeding edge art of overclocking an HDTV to 120Hz...
True 120Hz from PC to TV:
Make Your HDTV Accept Real 120Hz Refresh Rate
Just like overclocking a Catleap 2B, or the QNIX Q2710 Evolution 2, or the X270OC
...it is also possible to overclock some HDTV's to 120Hz from a computer too!
...Dozens of success reports are coming in, including:
HDTV Overclocking Instructions: Get 120Hz from a PC to a television
No fake frames. No interpolation junk. No Motionflow voodoo. True 120Hz!.
Try this with your existing HDTV.
Post your success reports here.

EDIT: A second avenue of reducing motion blur on HDTV's is to get a Sony TV with the low-lag Game Mode Motionflow Impulse feature (LightBoost style strobe backlight). It is only 60Hz but reduces motion blur by 75% and is console-compatible.

Resolution: 1920×1080 at 120 Hz
Using a Asus 3D tv driver I was able to force a 120hz output with windows 7 and my Vizio M420SL system info screen displays 120hz vertical frequency as well as my Catalyst control center. This TV is not a 3D but does have a native LCD refresh rate of 120hz.
Thank you blurbusters for your very helpful information. It took all day to find the right question to ask the great google search engine but when I finally asked “force 120hz pc” I found this page and now I am in 120hz, 42 inch, goodness. Next trick is getting passive 3d working. Thanks again.

The OSD reports 60hz and 3D mode detected. Colours are slightly different but there is no 3D being applied. I have verified that it does show 120 unique frames.
So, when you try outputting 120hz to your TV don’t assume the OSD is giving an accurate report. It may say 60hz yet actually be showing 120hz.

Resolution: 1080p @ 140Hz, and 720p @ 254Hz!

The overclock results:
UHD 3840×2160 was 30Hz max now 38Hz (up to 40Hz by reducing the extra pixels/blanking in the stream but with minor artifacting)
QFHD 2560×1440 was not there now 82Hz
HD 1920×1080 was 60Hz max now 140Hz (I checked with RRMT Refresh Rate Multi Tool and it actually did it without dropping)
QHD 1280×720 was 60Hz max now 254Hz (checked again with RRMT but it was too fast for my eyes then I took pictures and video)
(NOTE: Cost only $600 in China! Not available outside of China yet at this time.)

“720p@120hz confirmed working. Kinda funny, before on 1080 I didn't notice a difference figuring I'm just getting too old for this stuff, having never used a 120hz monitor before, but I knew instantly with the real 120hz that it's working. What a huge difference in smoothness and reduction in blur. Just nuts. Tested with RRM (Refresh Rate Multitool) as well to verify.”
(NOTE: 720p was good; 1080p was frameskipping, but may be DVI adaptor (limitation). Best to test using direct HDMI-to-HDMI connection from PC-to-TV.)
