But in my Macbook the colors and contrast being terrible. Any color grey on a white background doesnt even seem to render. I connect the monitor on other pc and the quality are better. Someone help me ?

Have you tried to calibrate the monitor? Use your "ColorSync Utility.app" which is in Applications, Utilities. Let us know if that helps. If not, we can recommend another color calibration application.

Also, make sure you're connecting to the monitor from the MiniDisplay Port via DVI or HDMI not VGA.
