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.

    2160p at 36" would be the same pixel density as 1440p at 24", and I can confirm from using a Lenovo L24q that that is in fact an excellent pixel density for productivity.
  • boeush - Friday, January 3, 2020 - link

    That said, 38" shouldn't be terrible either, and possibly even better (by your numbers, the pixel density would be equivalent to 25" at 1440p). If only anyone from the OEM world were paying attention to these suggestions... *sigh*

    This is how I use my 40" 4k Iiyama. Everyone says I'm nuts when they hear I have a 40" monitor, but when they realize it's practically 4 20" Full-HD monitors set up in a 2x2 grid they start to realize how useful it really is.

    It's the first time I've had a single-monitor setup since about 2001.

    sorry i think you are completely wrong

    it is called "Windows" for a reason, and you can resize your content to be any size you want it to be

    There is nothing in my post that should trigger this sort of fight or flight response.
  • Alistair - Thursday, January 2, 2020 - link

    You're interpreting my post in your own voice. A large monitor is useful because we don't have to use our applications full screen, we can use "windows" when we use "Windows".

    "The UltraSharp U4320Q supports only sRGB color gamut, which is good enough for Windows…" This is such a low standard; Windows HDR integration could be a lot better to massively catch-up w/ MacOS.

    Monitors of this ilk should have HDR10+, HLG, & Dolby Vision HDR w/ HDR1000. Weird Asus & others get this, but then again those features seems to priced at a point creative & eng professionals are easily able to acquire at work vs. other pros.

    This is nice, coming from an old 2560x1600@30" with a 0.25 mm² pixel pitch, would be a good upgrade to 3840×2160@42.5" with a 0.245 mm² pixel pitch.

    Feels like at home, just a bigger display, without some annoying grid-borders, great for productivity.

    Priced almost the same like Dell UP3017.

    Good news!
  • hbsource - Thursday, January 2, 2020 - link

    The aspect ratio isn’t as good as the Dell 30”
  • mobutu - Thursday, January 2, 2020 - link

    yeah, it's 16:10@30" versus 16:9@42.5"
    but still, it's 1600p@30" versus 2160p@42.5" ... I can live with that seeing as I gain more vertical space anyway ;)
