It is also the step-up in size from the smaller PN50B530, with the same features except for screen size and upgraded speakers, 15W instead of 10W. The PN58B530 does not have two of the PN58B540's features, which are Samsung's "WideColor Enhancer2", which is supposed to allow selectable color settings, and a slightly easier to use HDMI interface to connect multiple HD devices to the TV.These include Samsung's e-panel glare reduction, better energy efficiency than previous models, and faster image processing when game mode is on. This TV has numerous video inputs and a dual-tuner for digital or standard signals.
