Yes, you will have less color resolution, but 16 bit is not too bad for
a desktop... If that is not good enough for you, then you could try to
reduce the vertical refresh rate of the monitor to 60 Hz
in /etc/X11/xorg.conf (if you did not already do that). In Section
"Monitor" you have to add (or change) the line:
VertRefresh 60.0 - 60.0
Success.
