Make sure you have the vsync and hsync values correct for your monitor
(see the monitor manual) otherwise you will get this.
Subpixel rendering should not affect this, but it can improve clarity as
the xserver knows more about the screen so can change the way pixels are
lit up to look better.

Thanks Anton,
I checked with the manual and changed what xorg.conf had to the values
in the manual (Horiz: 30 - 82; Vert: 50-75) but everything looks the
same (running at the recommended 1680x1050) with the extra space on
top. The manual also states that I should be running at 60 Hz but the
monitor reports that my video card is running the Horizontal at 65 KHz
and the Vertical at 60Hz, is this something that can be changed in
xorg.conf or am I mixing information there?
My Nvidia card is fairly old, could it be a video card issue (looking
for an excuse to buy a new one anyway). Speaking of, using the nv
driver produces the same result as the binary driver.
