Our Verdict

LG UA77

Samsung U7900F

The Samsung U7900F and the LG UA77 are both poor TVs, but they trade blows in a few different ways, and the best one depends on your viewing environment. The LG gets quite a bit brighter and handles reflections better, making it the safer choice for a moderately lit room. The Samsung has much better contrast, though, so it's the better choice for a dim or dark room.
