    I have an Nvidia video card i think it is the 6800 but not certain. It has a DVI and VGA output. I have 1 17" monitor which is my main one. I wanted to set another one up for elsewhere. It is a 15" monitor and is LCD (like the other one, they are in fact the smae make).
    However, when i plug the 15" one in, I get a picture but there is a white box with red writing moving around the screen saying "Input not supported".
    I am confused as to why this is happening when the picture on the screen is there. It is not perfectly focus (although close) so I guess it is something to do with a clash of resolutions.
    Is there anything I could do about his or a resolution I could set that would work with both?
    Thank you,

    You need to configure (under display options on the PC) the refresh rate and resolution to match the rate the LCD has. For a 15" it will be 1024 x 768 at 60 Hz refresh in most cases.
