If you like to customize display settings, you might try DDCcontrol – a tool that takes the headaches out of display configuration.
DDCcontrol lets you manage your monitor settings without touching the hardware controls. DDCcontrol relies on the DDC/ CI control channels. DDC, which stands for Display Data Channel, is a serial communication interface between the graphics adapter and the display. The interface was standardized by VESA. Normally, the interface is just used to send data to the graphics driver; the driver uses this information to choose the right resolution and refresh rate settings. DDCcontrol sends data back in the opposite direction. The documentation tells you which displays and graphics adapters the program supports. If your hardware is not on the list, it could still be worthwhile to try the program.
