    HDMI output is black and white on external monitor


      I have a Lenovo B570 running a Intel Pentium B940 and a Intel HD Graphics card.   I have been utilizing an external monitor (connected via VGA) and recently added a 2nd external tv monitor connected to the HDMI port.  All was good - utilized the two external monitors, while disconnecting the laptop's monitor.   Today I booted my computer ant the monitor connected to the HDMI was in black and white. 


      I first checked the options for both Windows 7 and the Intel Graphic and all appears normal.

      I then checked to make sure the graphics driver is updated.

      Lastly, I bought a new hdmi cable and still black and white. 


      Is there an option in the settings that has been changed or a way to reset to default settings?
