Measurements &
Review by Belgium HardwareReview by RtingsMatte 2018 model with 40-60hz AMD Free-Sync, 2x USB 3.0, and a height adjustable stand. It is quite accurate and offers excellent all around performance. It can display an HDR signal, but all it can do is max the brightness resulting in black looking grey, more obvious back-light bleed and glow, and vastly de-saturated HDR content viewing since it lacks a wide gamut panel. Keep HDR turned off.
LG 27MD5KA
Measurements by Belgium HardwareFully adjustable matte and wide gamut 5120x2880 LG AH-IPS panel with a perceived black depth increasing matte grey bezel, a webcam and 3x USB-C. It has
excellent preset RGB balance accuracy, but slightly too high preset gamma and the
Adobe RGB mode RGB balance is worse.
LG 27UL500
Measurements and
Review by Belgium HardwareMatte height adjustable 3840x2160 LG AH-IPS panel with 40-60hz AMD Free-Sync, Displayport, 2x HDMI 2.0 and 3.5mm Auido Out. The 27UL500 is least accurate of the tested 27" 4K monitors on the market, and while not awful, is not competitive, nor worth purchasing. It has low 2.05 (average) gamma and slower pixel response times than the many better options.
LG 27UL550
Review by NCXMatte height adjustable 3840x2160 LG AH-IPS panel with 40-60hz AMD Free-Sync, Displayport, 2x HDMI 2.0 and 3.5mm Auido Out. The UL550 is pretty much the same as the UL650 aside from the fact that the UL550 has a perceived black depth increasing dark matte grey bezel while the UL650 has a fake bezel or frame-less panel with a perceived black depth reducing inner black bezel. The 27UL550 is quite accurate, especially when set to the SMPTE-C mode, as well as offers top tier 60hz gaming performance (negligible input lag and fast pixel response times without overshoot ghosting). Belgium Hardware's
Standard Mode RGB Level Measurements (as well as others) are extremely similar to
the 27UL550 I tested.
