g'day mate,
i can't find anything specific for that monitor.
however, firstly, try to create a new resolution and hz (1920 x 1080 120hz) in nVidia control panel.
this works for my tv.
if that doesn't work apparently there are potentially ways to 'overclock' your tv to do it. you seem to have the right type of tv as it has a high hz/3d.
there used to be a website called blurbusters.com that gives guides but i can't seem to get onto it.
here are a couple of links that give some info. there is a program you can upload and try and there is also a way of testing if the tv is actually showing a true 120hz or if you are just getting an extra 60hz interpolation. anyway i hope that helps. i would definitely try it with the nVidia control panel and then perhaps try the monitor test.

Quote: EDIT: New Blur Busters Blog page posted after I posted this forum post: HDTV Refresh Rate Overclocking
Some HDTV's can be 'overclocked' with native 120 Hz HTPC signal.
For example, the Vizio e3d420vx HDTV can successfully display native 120 Hz PC signal through the refesh rate overclock method. You need to use an EDID override INF file (like those found on 3D Vision Blog, google "EDID Override"), or use PowerStrip to force 120 Hz. Unfortunately, PowerStrip stopped working on some newer graphics cards, so we need to use the EDID override method. There's a post covering some experience overclocking 120Hz.
Try it out on your HDTV. It probably won't work, probably less than 25% of HDTV's will function with native 120 Hz through the refresh rate overclock method. Some HDTV's inadvertently support the dotclocks necessary because active shutter 3D @ 60Hz can have the same dotclock frequencies as 2D @ 120 Hz.
Instructions: How to Overclock an HDTV to 120 Hz Native From a HTPC
(50% less videogame motion blur)
NOTE: You must have a HDTV that already has internal electronics for 120 Hz for a different purpose (e.g. motion interpolation, 3D shutter glasses) but otherwise has an EDID that tells you it only supports 60 Hz. Even so, there is no guarantee the electronics can be "coaxed" to accept native 120 Hz. It only sometimes works with some models of HDTV's.
Get a high-end Radeon or Geforce product. I recommend Geforce GTX 680
...As a side effect, the nVidia Geforce cards are also compatible with LightBoost strobe backlights (found in zero motion blur monitors like ASUS VG248QE and BENQ XL2411T) which brings CRT-quality better-than-plasma motion to high-end desktop video gaming (LightBoost HOWTO). Consequently, nVidia Geforce products are currently preferred (at this time of writing) over AMD Radeon product.
.
Connect your computer to the HDTV first.
...Turn off mirror mode, make your HDTV your primary display. Otherwise, it won't work properly.
.
Install an EDID override file. These are sometimes difficult to install.
....If you need to get familiar with how EDID overrides are installed (e.g. 3D Vision Blog Instructions (different purpose), Microsoft technical info).
(a) Download one of the 1080p@120Hz files (1080p@120Hz EDID Overrides in this thread). Your HDTV will 'masquerade' as a 120 Hz computer monitor, allowing your graphic card to 'force' 120 Hz to be sent into your HDTV. Then you can see if the display successfully syncs to it!
(b) To install an EDID Override, download the file, then right-click this INF file in File Explorer and select “Install”. Next, go to Device Manager and right-click your monitor, select “Update Driver Software”, then “Browser my computer…”, then “Let me pick…”, then disable “Show compatible hardware”, then select the “EDID Override” from manufacturer ASUS (even if you don’t have ASUS), and then reboot.
(c) IMPORTANT! (Windows 8 specific): If you’re installing under Windows 8, follow these instructions to disable driver signature enforcement before installing this INF file. The INF file is installed via right-clicking the monitor in Control Panel -> Device Manager, and updating its driver.
.
Test the 120 Hz refresh rate
...If it fails, try other refresh rates such as 75Hz and others.
.
Test all connections. VGA, DVI, HDMI
...Sometimes, a HDTV successfully overclocks to 120 Hz on one connection only.
...Remember to use sufficient cables (Dual-Link DVI cable, HDMI 1.4 compliant cable)
.
Try testing 720p @ 120 Hz instead of 1080p @ 120 Hz
...This more commonly works in an overclock attempt since it's the same dotclock as shutter 3D 720p @ 60 Hz per eye (which is actually officially supported)
.
If all else fails but you want to buy a HDTV that works with native 120 Hz, you need to do testing
...Currently, refresh rate overclocking is bleeding edge territory currently being trailblazed by sites such as 120hz.net and others. This is a new technique that is only slowly gaining use by power users. Thus, you have to test with a 120 Hz PC until you find one that works with native 120 Hz. Within a few months, there might be an official list of overclockable HDTV's. If you have a new model to add, email me at mark[at]blurbusters.com
...This is currently time consuming because you need to reinstall the EDID override file every single time.
.
Or wait for the Geforce Titan.
...I've heard that it has an easy display overclock feature, eliminating the need for pesky EDID override files!
.
Will it damage my HDTV?
...Not likely. Fortunately, no display has shown adverse behavior because they are already designed to be 120 Hz for other purposes (3D shutter glasses, frame interpolation, etc). The chief problem is simply the firmware of the HDTV wasn't programmed to make it easy to accept 120 Hz native from an external source. Occasionally, this is possible to override, as is has been successfully accomplished with an EDID override with certain models (e.g. Vizio e3d420vx) and a number of other models.
NOTE: This is an old version of this post. The updated HOWTO, including frame skipping tests, is found at HDTV Refresh Rate HOWTO: 120Hz from PC to TV
