Our Verdict
Samsung UE590
LG 27UD58-B
The LG 27UD58-B is much better than the Samsung UE590. The LG 27UD58-B has much wider viewing angles, and there are no duplications in moving objects as the backlight is flicker-free. The 27UD58 has better gray uniformity, which is great for watching streaming sports.
