Our Verdict
Sony X750F
LG UM6900
The Sony X750F is a bit better than the LG UM6900 for most uses. The Sony is brighter, and it has an optional black frame insertion feature. The LG uses a less accurate RGBW pixel structure, which isn't great for use as a PC monitor, but it has lower input lag, so it's a bit better for gaming.
