Topic: LG 42LA6200 120Hz 3D Smart TV, unable to set refresh rate to 120Hz?
What the title says, pretty much. In a nutshell, we've finally upgraded our TV at home, I saw a chance, took it, and insisted it HAD to be 120 Hz. Unfortunately 120 Hz screens are a rarity where I live, thanks to our wonderful (/sarcasm) import laws and my government's policy of systematically screwing over anyone who tries bringing anything from outside the country. It also appears that due to the locals' severely inefficient way of handling technical specifications, the best way to ensure the TV you're buying has 120 Hz is getting one with 3D support.
So we got a LG 42LA6200 (official specs page: http://www.lg.com/us/tvs/lg-42LA6200-led-tv )
I promptly connected my computer, which I'm fairly confident it's up to spec (i5 3570, GTX 650 Ti Boost, 2x8GB RAM @ 1600, Win7 64 bit) to the TV, but to my disappointment, I seem to be unable to set the refresh rate any higher than 60 Hz.
Is there anything I can do to get a screen refresh rate of 120 Hz?
I've already bought a new HDMI cable that claims to be 1.4b which I'm using right now, but thanks yet again to my country's import laws, it's a generic brand cable and I can't be sure it actually IS 1.4b, since the cable itself doesn't say "1.4" anywhere on it.
I could simply make a new unsupported resolution from the Nvidia control panel set to 1080p @ 120 Hz, but I'd rather be absolutely certain I won't blow up anything (mostly and more importantly the TV) before I do that.
Any help would be amply appreciated
