I’m running it on a laptop which has VGA and HDMI only, no DVI. So I plugged it in to HDMI. Tried every method above (I don’t have glasses) , but I cannot get to have refresh rates higher than 60. And I cannot get Lightbosst active (it is greyed out by default) in monitor’s OSD menu.

While trying methods there were 2 things i noticed;
-Nvidia drivers start to show DVI connection instead of HDMI after the hack.
-While trying different methods above a few times, I was once able to enable stereoscopic 3d turn on and off. But it requires setting up again now after I restore the settings to defaults.

Specs;
Win7 x64 Home prem
Gtx460m
It doesn't work with hdmi, it has to be dual link dvi or displayport.

Damnit, I shouldn't have bought this monitor in such a rush, without researching more... Although I think I've read that it's possible.

This guy claims that 1.4b might do the work: http://www.tomshardware.co.uk/forum/331322-33-120hz-hdmi#7610410
And in wikipedia it says something backing up that guy: "HDMI 1.4b was released on October 11, 2011.[150] One of the new features is that it adds support to 1080p video at 120 Hz."

Does this mean it will be possible if i get a 1.4b cable?

Maybe if your laptop had a 1.4b HDMI port.

Sometimes when I'm playing games such as CS GO I get really bad choppiness out of nowhere. It's like my game starts chugging all of a sudden. To fix it I quickly disable lightboost and then re enable it. It's weird and only happens about once every few hours of play.

I doubt my 2 year old Asus g73sw-a1 has 1.4b support. BTW, does VG248QE's HDMI input support 1.4b anyway?

Ok, so I need a workaround here then. What if i get a PCMCIA or a USB Card(?) that has a DVI or DisplayPort on it and plug it to my laptop?

No current monitors, including the VG248QE, feature HDMI 1.4b. You need to use DVI or DisplayPort to take advantage of the full refresh rate and technologies that use it 'out of the box'.

Not even the Benq XL2420tx? I know the XL2420t doesn't support 120hz over HDMI, but supposedly the more expensive XL2420tx does?

Can I use something like http://www.amazon.com/dp/B008CXFM64 to have proper DVI or DP support for 120hz lightboost mode?

The difference between the 2420t and tx is the tx has a built in 3d emitter other than that it's the same monitor.

Someone was able to overclock the HDMI connection of one of the 120Hz monitor (forgot which) to 120Hz, using the HDTV Refresh Rate Overclocking HOWTO. You need direct HDMI-to-HDMI, from the HDMI port of the graphics card, to the HDMI port of the display. Sometimes 1080p@120Hz works. Not always, but HDMI 1.3a has the bandwidth to allow it, just not an officially documented/supported mode.

Not guaranteed to work. But it has worked sometimes before even with HDMI 1.3 chips.
