All tvs are 60hz and use motion interpolation. It does not matter if you have a 120 or 960hz tv, they all use motion interpolation.

http://en.wikipedia.org/wiki/Motion_interpolation

 

You cannot use 120hz at 1080p via hdmi 1.4a, only at 720p.
a TV is not like a PC monitor where u can either use DP(display port), or DUAL LINK dvi-d cable for 1080p/120hz

Interesting read.
So I guess that begs the question:
Why is the "true motion" option grey (un-selectable) when outputting at 1920x1080@60hz from the graphics card?

I didn't mention it, but I actually did try 1280x720@120hz with the same results as 1080p@120hz--a black screen.

HDMI can't do 120hz.

Set it to 720p and see if the option becomes available

Need to use HDMI to turn on frame interpolation and simulate 120hz. VGA is not usually supported by the onboard hardware in terms of advanced picture control and simulated 120/240hz.

Obviously answered already.... all HDTV's are 60hz MAX. If you are watching 23.xx fps video ie: a blu ray/film rip I would suggest running your TV at 23/24 or 48hz to get the smoothest picture possible.

Ideal imo would be running the tv at 23.97hz via HDMI and using the onboard processor to simulate 120hz. That would technically give you 5:5 pulldown, or 5 perfectly duplicated frames as opposed to 3:2 pulldown which is common with running 24fps media on a 60hz signal.

720p @ 60hz
TruMotion still grey.

You lost me at 23.xx .

I am using an hdmi cable, yet frame interpolation is not simulating my 120hz.

 

end thread.

I just tried a different hdmi port on the tv and BOOM SHAKALAKA!

I literally fooled with this for months and bought different graphics cards/cables, tried wipe/reinstall.

24 fps films are not really meant to be played at 60hz, but the industry has sort of force it on us because NTSC TV has always been 29.97 fps.

You can research 3:2 pulldown a bit more if you want to understand it, but ideally you want to run a refresh rate that is a multiple of 24 when you are watching anything that was originally a movie meant for DVD/BD. IE: 48hz, 120hz, 240hz, etc... It will result in the smoothest possible motion.

Running a 24 fps source on a 60hz display will result in the TV having to mess with the frames to match the refresh rate. Its funny though because this is how 99% of the people who have an HDTV do it unless they have a TV and BD player that natively support 24fps playback and are matched to work with each other.

 

After you changed the HDMI port, how does it currently work?

Very good stuff. I will play more with graphics cards settings to see if I notice a difference.
(though I'm the guy that thinks 720 looks just as good as 1080 or even 2k,3k,4k until you get a display over 50")

Nothing changed really.
Video card settings are the same, 1920x1080@60hz
TV video settings are all the same, except the options for TruMotion are ungrayed out.
For whatever reason HDMI port one intentionally disables those settings.

 

This information shows up as a first page search result (June 11th, 2013) in Google USA, when searching for 120Hz from PC to TV. So I'm bumping this outdated but still-visited thread to ADD important new information:

There are now many televisions that can accept 120Hz from a computer (in an undocumented way). This is done via ToastyX Custom Resolution Utility, or EVGA PIXEL OC utility, or other utilities -- to force 120Hz from a PC to TV. True native 120Hz, not interpolated 120Hz. Includes confirmations via Refresh Rate Multitool!

True 120Hz from PC to TV --
HDTV Refresh Rate Overclocking HOWTO

Several success reports include:
-- Vizio M420SL and e3d420vx (1080p at 120Hz from PC to TV)
-- Panasonic VT50 plasma (1080p@120Hz)
-- SEIKI 4K HDTV (1080p@120Hz).
-- Etc.

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.

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.)
