First of all a little bit of development. I changed the vertical refresh rate(on Gnome) from 50 to 57 Hz. And what you know now it is a lot better but not 100%. Now i'm using 1680x1050 resolution but LG's recommended resolution is 60 Hz. Is it possible to change vertical refresh rate to 60Hz system wide?
When you configured Xorg did you tell it to do sub-pixel rendering on your LCD screen? I've never used an LCD so don't know what this looks like).
actually i don't know how i answered that(sorry i'm a newbie)
What is the native resolution of the screen itself and what is the resolution you're trying to use in Xorg?
My monitor's native resolution is 1680x1050 and i'm using that.
