Polish Your Display With Nvidia Tool

First you must have a nvidia card and latest drivers. I dind't try it with LCDs but i think this tool is for CRTs;
To use this tool, right click on the desktop, click properties, then click advanced, then click your graphic card's name, then click tools and lastly click "Display Optimization Tool". It is very easy to use and effective. After using it all the colors are brigthened. If you dont know this tool you are losing sometihng.:)
I took some screenshots to show but they were all same. Becouse this tweak is all about display(monitor).
