I hooked up my computer to the LG tv with a RGB cable. The screen is cut off about an inch on the right and has a black bar on the left. I tried changing the resolution. I tried moving the screen in the Nividia control panel--it moved but the bar was still there on the left and it began to loose part of the picture on the left. (I have the screen set at its native resolution of 1900 x 1080)
Another problem is I can't hook the tv up with my HDMI cable (there's no signal) which I prefer as this carries sound and the RGB doesn't. It worked when I hooked up my sony laptop.
