The current crop of 28″ ‘4K’ UHD models make use of a fairly uninspiring TN panel. The resolution itself is certainly a nice addition, though we find ourselves far more inclined to recommend the 27″ IPS-type options. The Samsung U28R550 (or U28R55 or U28R550U of the UR55 series – additional suffixes and prefixes may apply) mixes things up a bit by offering a 28″ ‘4K’ IPS-type panel. Aesthetically the monitor has a smart business-like appearance, with a brushed metal effect silver-coloured bottom bezel and slender dual-stage bezels at the top and sides. These top and side bezels include a panel border that’s flush with the rest of the screen, plus a slim hard black outer bezel. The OSD (On Screen Display) is controlled by a small joystick beneath the Samsung logo on the bottom bezel.

A smart appearance

The monitor uses a 28″ IPS-type (In-Plane Switching or similar) panel with 3840 x 2160 (‘4K’ UHD) resolution, 1000:1 static contrast and 178°/178° horizontal/vertical viewing angles. The Innolux M280DCA-E3B AAS (Azimuthal Anchoring Switch) IPS-type panel, more specifically. A 60Hz refresh rate is supported alongside Adaptive-Sync, including support for AMD FreeSync with a 40 – 60Hz variable refresh rate range. The monitor supports 10-bit colour and features a flicker-free WLED backlight offering 90% DCI-P3 coverage for a vibrant look plus a 300 cd/m² typical maximum luminance. The monitor offers basic HDR support, responding to HDR10 content and putting its colour gamut and 10-bit colour processing capabilities to good use. It lacks sufficient luminance for even the most basic VESA DisplayHDR certification level, though, and does not include any local dimming on the backlight to enhance contrast. A 4ms grey to grey response time is specified (approach with caution), with some attractive additional features including some Low Blue Light (LBL) settings, PiP (Picture in Picture) and PbP (Picture by Picture) functionality. The included stand offers tilt as the only ergonomic flexibility but can be removed and an alternative attached using 75 x 75mm VESA. The ports face downwards in a recessed central area at the rear and include; DC power input (external ‘power brick’), DP 1.2a, 2 HDMI 2.0 ports and a 3.5mm headphone jack.


Some VESA holes
