I'm unable to set my PC to have a refresh rate of 120hz when connected to my LG t.v via HDMI 1.4 I've attempted it while going through the surround sound receiver (Yamaha RX V373) and while connected directly to the T.V. I'm using a GTX 660. In fact, when I change the refresh rate from the default 59 to 60, it's back at 59 once I go back into the display settings. I've changed it in both the Nvidia control panel and the Windows resolution settings. When I try creating a custom resolution and enter 120hz as my refresh rate, the screen goes black and my T.V eventually tells me there's no signal. My T.V is a LG LE5400 - http://www.lg.com/us...400-led-lcd-tv . I have the latest Nvidia drivers and I've tried other HDMI cables.
It may be worth noting I can turn "TruMotion" on in my LG settings, but the PC itself won't allow me to set the refresh rate at 120hz so I would imagine it would then be a moot point to enable TruMotion on my tv.
