Further information on supporting our work.The ‘desktop real-estate’ benefits and pixel density of a ~32″ screen with ‘4K’ UHD resolutions are very attractive. The Dell U3223QE of the UltraSharp series offers this combination. The monitor offers slender bezels at all sides, a dual-stage design with a slim panel border flush with the rest of the screen plus a thin hard plastic outer part. The stand uses a silver-coloured plastic with a satin finish, commonly seen on models in the series. The OSD (On Screen Display) is controlled by a joystick at the rear, towards the right side as viewed from the front with separate power button also included.
The monitor employs a 31.5″ 3840 x 2160 (‘4K’ UHD) ‘IPS Black’ panel from LG Display with 60Hz refresh rate. Of particular note is a specified 2000:1 static contrast, double the usual 1000:1 for the panel type. Specifics from the panel manufacturer suggest a special polarising filter is used to reduce ‘IPS glow’, too. Other points to note include a light or very light matte anti-glare screen surface, 178°/178° viewing angles and 10-bit colour support (8-bit + FRC assumed). A flicker-free WLED backlight provides a 400 cd/m² typical maximum luminance and 98% DCI-P3 colour gamut. The monitor is factory calibrated with specified DeltaE <2 within the sRGB and DCI-P3 colour spaces, using the appropriate presets. The peak of blue light is shifted to less energetic wavelengths, potentially aiding viewing comfort (TÜV Rheinland certified hardware solution). This forms part of the ‘ComfortView Plus’ solution, which also includes the usual ‘ComfortView’ Low Blue Light (LBL) setting for more relaxing viewing in the evenings (for example).
VESA DisplayHDR 400 support is included, allowing the monitor to respond to HDR10 content and put its relatively generous gamut to use alongside 10-bit colour. It doesn’t require local dimming to enhance contrast or a particularly high brightness by HDR standards, however. A 5ms grey to grey response time is specified, but as usual approach this figure with caution. The stand attaches via a quick-release mechanism and can be easily removed for alternative 100 x 100mm VESA mounting, if preferred. The included stand offers full ergonomic flexibility, including height adjustment (150mm or 5.9 inches) and pivot into portrait. The ports face downwards and include; AC power input (internal power converter), HDMI 2.0, DP 1.4, DP 1.4 out (for MST daisy chaining), USB-C (90W PD, DP Alt Mode, upstream data), a 3.5mm audio output, USB-C upstream (data only), 4 USB 3.2 Gen2 ports and an RJ45 port. A 5th USB 3.2 Gen2 port and USB-C downstream port is located at the bottom of the screen outside the main port area, for easy access. KVM support is offered to allow USB peripherals to be easily shared between 2 systems, with 2-source PbP and PiP also supported.
Further details can be found on the manufacturer’s website. The monitor is listed for ~$1150 USD.
