Our Verdict
LG UK6570
Samsung RU7100
The Samsung RU7100 and the LG UK6570 are very similar overall, but they use different panel types, each with their strengths and weaknesses. The RU7100 uses a VA panel and has much better dark room performance, thanks to the excellent contrast ratio. The UK6570, on the other hand, except for the 70" size, uses an IPS panel. This results in worse dark room performance, but much better viewing angles. Beyond these panel differences, the UK6570 can remove judder from 24p sources, and it has better reflection handling.
