Our Verdict
Samsung RU7100
LG UM6900
Although they use different panel technologies, the Samsung RU7100 is better than the LG UM6900. The Samsung has much better contrast, is a lot brighter, and it has an optional black frame insertion feature. The LG, on the other hand, has better viewing angles, better reflection handling, and can remove judder from 24p sources as well as the internal apps. The LG is worse for use as a PC monitor, though, as it uses the less-accurate RGBW sub-pixel structure.
