I know there are Divi to d-sub adapters for video.
I need to make a dual monitor setup. will these adapters cause my screen to loose brightness, or contrast or any degregation of screen image?

any good sources for inexpensive or refurbished monitors to refur me to?

any help appreciated

    What is your source graphics card or chipset?
    Do you need separate displays or just to clone the same output to both screens?

    If you are going to have two separate displays this will depend on what is producing the image
    Some graphics outputs can already cope with generating two separate images from a single output (if these cases a DVI-D > D-sub splitter will produce two separate images using different pin-sets so without any reduction in image quality), others can't and the best you'll then manage is to produce identical outputs by physically splitting the signal in two.  Over a short distance the effect of a simple split shouldn't be noticable but the split will cause the signal to degrade quicker along the cable.

    It really would help to know what is making the image to advise you better.

    Accepted Solution

    If all you are doing is converting one output port from DVI to VGA (d-sub), there should be no loss in signal - the DVI-I port has the necessary pins to directly wire it to an analog VGA port.  If you have a DVI-D port, you cannot use a converter, as it is missing the necessary pins.
