The Samsung Plasma 4 Series shouldn't be confused with the Samsung 4 Series in the LCD market, both released in 2008, despite their very similar names and specifications. Both series lie at the entry-level of their respective lineups and feature a native resolution of 720p, the notable difference is the panel technology used, with this line being plasma. Adding to the confusion is that the 4 Series of plasmas are split further into two, as the 450 models are slightly more advanced with 3D capabilities. The step-up from the 4 Series is the Plasma 5 Series which is the entry-level 1080p line.
