Dell was among the first companies to introduce a 43-inch monitor designed for office and environments where multi-display configurations have traditionally been used. At CES, the company rolled out its new UltraSharp U4320Q 42.5-Inch 4K display that features a newer panel, an improved stand, and a USB-C input.

Dell continues to position its UltraSharp U4320Q monitor as an ultimate tool for productivity applications as well as a replacement for multiple smaller displays. To that end, specifications of the display are pretty modest: a 3840×2160 resolution, 350 nits typical brightness, a 1000:1 contrast ratio, 178°/178° horizontal/vertical viewing angles, a 5 ms GtG response time in Fast mode, and a 60 Hz refresh rate. The display does not support HDR10 transport, a variable refresh rate technology, and other multimedia enhancements. Being a ‘workhorse’ type monitor, the UltraSharp U4320Q supports only sRGB color gamut, which is good enough for Windows.

The key improvement that the UltraSharp U4320Q has over its predecessor is its adjustable stand that can now regulate height, tilt, and swivel, as well as a modernized set of connectors. In addition to usual DisplayPort and HDMI inputs, the new unit has a USB Type-C port that supports DisplayPort alt mode and can deliver up to 90 W of power to the host. The monitor fully supports Picture-by-Picture and Picture-in-Picture capabilities and can work with up to four PCs at once. Unfortunately, the display does not have a built-in KVM. Moreover, it does not have built-in speakers either.

    Seems like you are gaining ~5" of vertical space in the move - 12.54cm, specifically.

    better off buying Samsung's best 43 inch TV for half the price though

    Missing HDMI 2.1. Kind of weak in the "updates" category over the prior model. A wider color gamut is really going to be "required" for devices over 1K, imo, business or not. Engineers will definitely consider the lower gamut to be a negative. And worse, there are better panels for the same money.

    It certainly has a sturdy stand but I don't think it should cost a lot more than a 4K TV.

    What is new about this one? Just curious. Is it the size?

    -focus on general office productivity, usability and ease of use;
    -can show content from four different devices simultaneously in four quadrants for serious multitasking;
    -4K resolution with no need for scaling by the operating system;
    -IPS panel @42.5" (at this size almost all competitors use VA panels ... if not all);
    -ergonomic stand (height, tilt and swivel);
    -easy connectivity with USB type-C provided for single cable connections and up to 90W of power delivery.

    I have the U3219Q and love the USB-C connectivity. I can bring my work laptop home and quickly connect. Or my son can hop on it with his Mac. Of course they come out with the 43" right after I got mine :) I find I have to use scaling at 4K with the 32" for my old eyes. The 43" would be amazing!

    I’m hoping this is an RGB pixel stripe. Ive only ever seen 43” monitors so far that use strange stripes and cause big issues, particularly under Mac.
    I’m a multi monitor user and I find the idea of this size and resolution amazing as its 4 x 21.5” 1080p screens but can be used any way I wish.
    Just need to get the RGM pixel stripe and I’m set!

    I needed more pixels as I work a lot with large excel sheets, powerpoint decks, word documents (books) and graphic design (adobe xd). At the same time, give my middle age, I use progressive lenses so I need the display to be a bit forgiving too by having more room to zoom in and out as I wish.

    I bought a 32 inch 4K monitor but found that at native resolution, the menus were hard to see. In other works I would never be able to use the full 4k. I considerered a 38 inch curved screen, but for the price (usd1200) was not impressed with the meagre increase in pixels, especially on the vertical, where you only get 1600 pixels (cf 2160 pixels on a 4k screen).

    In the end I purchased this Dell U4320Q and I am really happy. The panel is very homogenous, no dead pixels, no flickering, no shadows or problems that i had read wbout with so many other monitors regardless of manufacturer.

    Initially, I thought I had made a huge mistake! It is a big monitor. But one day later, I find my prductivity has improved measurably. I use it at native resolution, at a distance of 60-70cms. The menus are readable. Text is fine. I am happy to edit docs at 0% zoom (i.e. no zoom). But when needed, I CTRL roll the mouse wheel to zoom into anything and still have a massive 4k pixel space to play with.

    It's bright enough for working like this. I run it at 30% (evenings) to 50% (bright days) brightness. This panel is not bright enough to display corporate media e.g. in an office entrance on a sunny day. But for home/office use at short distance it's just fine. The dell software makes it very easy to change the warmth and brightness without messing around with the pesky buttons on the monitor itself.

    Most of the time I find I use the left 2/3rds of the panel (Windows 10). I have my windows taskbar at the top which goes well with the top menus of applications. This minimizes eye travel. For apple users, you may find you have extra eye travel as the app menu is always stuck at the top and the content may be in a window somewhere in the middle of the screen. I typically reserve the right 1/3rd for reference windows e.g. file explorer windows with files to copy to or from or a browser running a page I am looking at at the same time as working on a document. So in this sense, a large panel is not a problem at all.

    I don't use multiple computers connected into the monitor at the same time. I did connect my old macbook pro (2009 17" version) running Catalina (hacked). It was perfect and had no problems driving 4k at 30Hz plus it's own laptop screen.

    All in all its a joy to use. I love seeing all 50-80 slides in a powerpoint deck so I can rearrange them, seeing huge amount of excel data and so on...! The same for viewing large numbers of photos in Google...! Everything is much faster.
