+Competitive sale price and superior performance compared to multiple more expensive 27" 4K monitors.
+Build quality and height adjustable stand
+Displayport and 2x HDMI 2.0 with Free-Sync and full 4K 60hz support
+AMD Free-Sync support over Displayport (40-60hz) and HDMI 2.0 (40-60hz)
+Balanced overdrive with no overshoot and very fast pixel response times
+Negligible input lag
+Nearly grain and sparkle free matte coating allows for increased clarity and vibrancy of light colors and white
+Great preset color accuracy, especially when set to the SMPTE-C Picture Mode
+Excellent calibrated image quality
+Minimal glow for a AHVA/IPS/PLS panel
+Reduced IPS glow compared to older panels from LG
+Wide viewing angles which do not negatively affect the viewing experience unless looking down at or viewing the monitor from above

-Fake HDR which should not be used
-Minor preset blue dominance
-Not as accurate as the cheaper Philips 276E8VJSB (review links)
-Height adjustable stand is too short to be useful

The LG 27UL550 is a great monitor without any major flaws, especially since it is competitively priced (for a 4K non-TN panel) and has less glow than many older, and many more expensive AHVA, IPS and PLS panels.  It does suffer from a preset blue tint, but it can be reduced by switching the SMPTE-C Picture Mode, and the flaws are quite minor, even when compared to a nearly perfectly accurate calibrated monitor.  The cheaper Philips 276E8VJSB (review links) and more expensive BenQ PD2700U (review links) are a bit more accurate, but I don't know if they suffer from more or less glow, and they use fake bezel or frame-less casings with perceived black depth reducing inner black bezels while the 27UL550 has a perceived black depth increasing dark matte grey bezel.  I can attest to the greatness of the 27UL550 (for the price), but can't claim that it is the best affordable or budget 27" 4K monitor, or recommend it over the  cheaper Philips 276E8VJSB (review links) and more expensive BenQ PD2700U (review links), but I do recommend it over the 27" 4K IPS panels in the LG UD, UK and other UL series monitors, especially the overpriced 850 monitors which offer USB-C and 2x USB 3.0 ports but no performance improvements.
