Samsung's PN50C450 is a flatscreen plasma display from the 2010 lineup of entry-level 720p units. It has a 50" screen and is almost identical to the model below it, the PN50C430, with the only differences being that this one does not have a USB port, while it does have an additional HDMI port as well as a PC DSub connection. Other than these, the specifications are the same. These include a clear, glare-reducing coating that enhances contrast and black aspects of the image, an automatic light sensor that adjusts brightness to save energy based on room conditions, and built-in stereo speakers. It also uses the 600Hz subfield motion image blur reduction to make moving images more smooth. This model is slightly more expensive than the PN42C430.
