Digital input is a feature you won't find on many 15" LCD's but Samsung has included it on this model. A digital input on a flat screen is far from a must when shopping for one but nice to have. Looking at a monitor I could not tell you if it was using an analog or digital input and I am not sure there is anyone who could. Digital input is supposed to have less distortion but I don't think you can to tell the difference. Also if you are going to use a digital flat panel you need a video card with a DVI. The only real advantage I found with digital input is you do not have to adjust any of the screen settings at all.
