Our Verdict
LG UK7700
Samsung RU7100
The LG UK7700 and the Samsung RU7100 are different types of TVs, so if you have a dark room and you sit straight in front of the TV, the RU7100 is a better choice as it has deeper and more uniform blacks. If you have a room with a wide seating arrangement and many lights, then the LG UK7700 is a better choice as the image remains accurate when viewed from the side and the TV has better reflection handling.
