The 3 Series represents the least expensive entry level offering from Samsung and features a 720p native resolution in the larger sets, with the smaller sizes acting more as computer monitors. Similar to the L4000 series from Sony, the A330s strip away most of the extra features found in the more expensive Samsung lines, allowing consumers to purchase an LCD from a "top-brand" like Samsung without totally breaking the bank. The step-up line is the 4 series which retains the 720p native resolution, but adds more features such as a third HDMI input.
