Share this content

Details of Dell’s new U4323QE display have started to appear online, although an official product page on has not yet been launched. The U4323QE is a large 42.51″ sized display with a 3840 x 2160 “4K” resolution IPS panel and is aimed at general productivity and office environments, offering a range of modern connectivity options and features.

Dell U4323QE Specs

The screen is 42.51″ in size (43″ class) and uses an IPS technology panel from LG.Display. It has a 3840 x 2160 “4K” resolution which is useable on a screen this large without the need for any OS scaling. This gives you a nice large desktop area to work with at a comfortable text size.

In other specs the screen has a 5ms G2G response time, although this isn’t aimed at gaming really as it has only a 60Hz refresh rate. There is a 1000:1 contrast ratio, 350 nits brightness, 178/178 viewing angles, 1.07b colour depth and a standard sRGB colour gamut (95% coverage quoted). Strange in this day and age to have only a standard colour gamut to be honest.

The stand offers tilt, height and swivel adjustments (no rotate). For connectivity there are 2x DisplayPort 1.4 connections, 2x HDMI 2.1 (although see note below about available features), 1x USB type-C with 90W power delivery, data and DP Alt mode. There are also 3x USB-C upstream data ports for KVM functionality, 4x total USB A downstream ports, 1x USBV-C downstream data port, 1x RJ45 Ethernet and 1x headphone jack.

Picture In Picture (PiP) and Picture by Picture (PbP) modes are supported from multiple video inputs. A KVM function is also included. There are also integrated 2x 8W speakers on this model

Honesty around “HDMI 2.1” Capabilities

Within the user manual Dell list the following caveat for the HDMI 2.1 ports, which we applaud them for, as this provides proper transparent information about what is and isn’t supported. It looks like the HDMI ports are certified under the new scheme, but don’t include any of the capabilities you’d actually associate with HDMI 2.1. At least Dell are being open and honest about this, but it’s still a real pain that everything will be certified this way!

“**Not supporting the HDMI 2.1 optional specification, including HDMI Ethernet Channel (HEC), Audio Return Channel (ARC), standard for 3D format and resolutions, standard for 4K digital cinema resolution, HDR, Fixed Rate Link(FRL), Enhanced audio return channel (eARC) , Variable Refresh Rate (VRR) , Quick Media Switching (QMS) ,Quick Frame Transport (QFT) , Auto Low Latency Mode (ALLM), Display Stream Compression (DSC), and Source-Based Tone Mapping (SBTM).”

Pricing and Availability

Regional pricing and availability is not yet listed, but we would expect the official product page and further information to appear imminently.
