Our Verdict

Samsung RU8000

LG SM8600

The Samsung RU8000 and the LG SM8600 use different technologies, each with its strengths and weaknesses. The Samsung is better-suited for viewing in a dark room thanks to the high contrast of its VA panel. The LG is better suited for a brighter room, and the wide viewing angles of its IPS panel are better for side seating. Beyond these differences, the Samsung is brighter but has worse reflection handling.
