Dell UltraSharp UW3423WE with 34″ Ultrawide IPS Black Panel and USB Type-C

Share this content

For CES this week Dell have showcased their new UltraSharp U3423WE display, a 34″ ultrawide screen based on a new IPS Black technology panel. The screen has a curved IPS Black panel offering a 3440 x 1440 resolution and a 1900R curvature. IPS Black offers improved contrast ratio, black depth and dark content viewing angles, something that we took a look at recently in this video.

The screen is focused on general and office-type uses, providing a range of features and enhancements to boost productivity. There are USB type-C connection (with 90W power delivery) for single cable connectivity, as well as Auto KVM, an RJ45 Ethernet docking port, Picture in Picture (PiP) and Picture by Picture (PbP) modes. The stand also offers tilt, height and swivel adjustments.

In other specs the screen offers a 5ms G2G response time (Fast mode), 300 nits brightness, 178/178 viewing angles, 1.07b colour depth and a wide colour gamut covering 98% DCI-P3. It’s a 60Hz screen only, we have yet to see IPS Black used on any high refresh rate panels sadly.

There’s a very wide range of connectivity options with 1x DisplayPort 1.4, 2x HDMI 2.0 ports*, 1x USB type-C (with DP Alt mode and 90W power delivery) for video. There’s also a total of 5x USB A ports, 1x USB type-C data ports an audio output and an RJ45 Ethernet port.

Fake HDMI 2.1 being advertised!

*Note that Dell refer to the HDMI ports on this screen as being “HDMI 2.1 (TMDS)” in their product documentation. They go on then to say in the small print “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).”

This is, in our opinion, super misleading. These are basically HDMI 2.0 ports, with HDMI 2.0 bandwidth and capabilities. A casual buyer might see the HDMI 2.1 name, then also see a long list of recognised features in the small print and assume those are all supported, missing the “not” at the beginning of the sentence potentially.

We really don’t like this approach, and we would really expect better from a large brand like Dell. Just call them HDMI 2.0 ports if they only have HDMI 2.0 capabilities and not a single feature people associate with HDMI 2.1!
