The LG has a stable or non-wobbly height adjustable stand made of metal, 3.5mm Audio Out, Displayport, and 2x HDMI 2.0 inputs which all support 40-60hz AMD Free-Sync which I could only test with the Xbox One X since I do not have a compatible AMD or Nvidia graphics card. Unlike the majority of monitors made in the past year the LG 27UL550 has a perceived black depth increasing, sparkly, matte, dark grey bezel instead of a fake bezel or frame-less casing with a perceived black depth decreasing inner black bezel like the LG 27UD, 27UK and 27UL6-8xx series monitors. The height adjustable stand is too short when raised maximum height to be useful.
