I just purchased and LG 37Lh40 with HDMI and I have it connected to my ATI Radeon HD5770 card. The monitor/tv is capable of 120hz refresh rate but I can only get it to operate at 60hz. I have updated all ATI drivers and motherboard drivers, but when I go to device manager I get generic pnp and the drivers for the monitor is dated 6/21/06 version 6.1.7600.16385 I need to update the generic driver to a version capable of 120hz and can't find them I have the ATI display adapter in device manager latest version 8.671.0.0 installed but no help with refresh rate. I am running Windows 7 Ultimate with a Quad core 2.66 Intel and 4 gig of ram. Any help would be appreciated.
