The screen of Samsung Series 7 "Chronos" (NP700Z4 & NP700Z5) is more than decent but if you are looking for more sharp colors then you need to tweak to see the best display. However for that you need to have access to the screen color-calibration hardware such Spyder 3 or similar. You simply need to replace the ICC profile with the customized one. Then you can set the display for sharp images.
