The LG LK450 is one of the most popular TVs on the market, and by our guess the reason is simple economics: it's cheap, especially for a major-brand model. Like the entry-level non-LED competition from Samsung and Sony, this TV is stripped of most features aside from the screen. Unlike those TVs, however, its picture quality--hampered by poor black-level performance--isn't up to snuff. Since a picture is all you're paying for at this level, we find the LG LK450 tough to recommend.
