    I bought a 22" samsung widescreen and I have the option to choose analog or digital signal. So which one should I choose? What are the pros and cons of both?

    Digital is using DVI or HDMI. Analog would be using VGA. Digital (DVI/HDMI) is better.

    analog = can degrade, becuase of bad connection/bad wire..
    digital signal = 0s and 1s.... harder to degrade

    An analog signal is a raw signal, a digital signal is a cropped and averaged signal. If you have high quality hardware, an analog signal will beat a digital signal every time because quite a bit of information is lost in the digital-> analog conversion, while no conversion is necessary for analog->analog.

    However, digital signals enable far less expensive hardware to reach higher qualities. For cheap electonics (like the what you mentioned) you will want to choose digital. If you have a lot of money to spend, analog can be MUCH better than digital.

    Further, newer monitors and video cards are designed to send digital signals (and have already done the conversion from analog->digital). If you then output in analog, the conversion is not skipped, it is just reversed (with more data loss). Definitely choose digital.

    Tell me how that Samsung display is (and what model number). I have a DVI to HDMI cord here, just not sure which monitor to buy.
