Our Verdict
LG SK9000
Samsung RU8000
The LG SK9000 and the Samsung RU8000 have different panel technologies, each with their advantages and disadvantages. If you have a room with a wide seating arrangement, the LG is a better choice as the image remains accurate when you watch from the side. On the other hand, if you sit straight in front and dark room performance is essential, then you'll appreciate the deep uniform blacks the Samsung can offer. The Samsung also has a bit better gray uniformity and faster response time, which are great if you're a sports fan. The LG can handle reflections a little better, which is good if your room has many lights; it also has a local dimming feature to improve its dark room performance.
