The ‘4K’ UHD resolution offers a nice pixel-dense experience and plenty of desktop real-estate, when coupled with a ~32″ screen size. The LG 32UN500 and 32UN550 (32UN550-W and 32UN550-W owing to white rear) provide this, with the same homely styling adopted by earlier models from the company. A silver plastic stand neck and crescent shaped stand base is adopted. The screen has a ‘3-side borderless’ design, or more precisely a dual stage bezel design is used at the top and sides. This includes a slim panel border that’s flush with the rest of the screen plus a thin hard plastic outer component. The bottom bezel is thicker, matte black plastic with a mere sliver of panel border visible. The OSD (On Screen Display) is controlled by a joystick on the underside of the monitor, in the central region.
A 31.5″ 3840 x 2160 ‘4K’ UHD VA panel is used, more specifically the AUO M315QVN01. This has a 3000:1 static contrast ratio, 178° horizontal and vertical viewing angles and a light matte antiglare screen surface. A 60Hz refresh rate is supported alongside Adaptive-Sync, including AMD FreeSync with a 40-60Hz VRR range. 10-bit colour is supported and a flicker-free WLED backlight is employed, offering a 350 cd/m² typical maximum luminance and 90% DCI-P3 colour gamut. The monitor includes LBL (Low Blue Light) functionality, with a ‘Reader Mode’ aimed at enhancing viewing comfort. Basic HDR support is offered – it will respond to HDR10 content, allowing it to put its bit-depth and gamut to good use. But it doesn’t offer a particularly high luminance and no local dimming is specified. A 4ms grey to grey response time is specified (caution advised), whilst ‘Dynamic Action Sync) DAS’ low input lag operation is included. The included stand is tilt-only on the ‘500’ and tilt plus height adjustable on the ‘550’ – this is the key distinction between the two models. The ports face backwards and include; DP 1.4, 2 HDMI 2.0 ports, a 3.5mm headphone jack and DC power input (external ‘power brick’). 5W MaxxAudio stereo speakers are included for potentially fairly powerful sound output.
Further details on the ‘500’ and ‘550’ can be found on various regional websites from the manufacturer. The ‘500’ is available for ~$350 USD (£370) whilst the ‘550’ may be confined to other regions such as Asia.
