Dell this week began shipments of its curved ultra-wide 3840×1600 UltraSharp U3818DW display. The monitor is the fourth screen of this size and with this resolution on the market, and one of a few displays with a USB Type-C input (via DP 1.2 alternate mode). Dell is positioning its U3818DW as a business-class monitor, so it gets market-typical features such as an antiglare coating, but notably it does not get support for AMD’s FreeSync (which is available on competing monitors).

The Dell UltraSharp U3818DW is based on a 37.5” 8-bit + FRC IPS panel featuring a 3840×1600 resolution, a 24:10 aspect ratio, 2300R curvature, and 1.07 billion colors. This panel has rather unique specifications and comes from LG Display. So far, three displays have used the panel for monitors aimed at consumers. For example, LG’s own 38UC99 and Acer’s XR382CQK come with FreeSync support and up to 75 Hz refresh rate (LG’s one only supports 75 Hz when FreeSync is used). Moreover, ASUS’s Designo Curve MX38VQ has integrated wireless Qi charging, whereas the LG 38UC99 has Bluetooth speakers (to playback music from smartphones or notebooks without using wires), two consumer-oriented features. By contrast, Dell seems to position its UltraSharp U3818DW in a similar way that it positions a number of its other curved displays: as a solution for business users looking to do a lot of multi-tasking.

In a bid to better appeal to the target audience, Dell has managed to increase maximum brightness of its U3818DW to 350 nits (from 300 nits on competing monitors), added an antiglare coating, and also added support for Dell's Command remote management capability. Each screen is sRGB-calibrated to Delta E < 2 accuracy, which is important for those who work with color-managed content. Meanwhile, the monitor also technically supports the DCI-P3 color gamut, but only covers 78.1% of it.

Dell’s formal positioning of the U3818DW does not really curtail its advantages for home users. Its resolution and the aspect ratio are well suited for displaying HD and UHD content filmed in an aspect ratio of 2.35:1 or 2.40:1 (a lot of movies are shot in such aspect ratios) as well as for games. Meanwhile, the monitor is equipped with HDCP 2.2, so it can display protected UHD content transfered to it using one DP 1.2 or two HDMI 2.0 inputs.

Dell’s UltraSharp U3118DW is now available directly from Dell for $1500, which is a bit lower than the price of LG’s 38UC99, but higher compared to similar displays from Acer (available now) and ASUS (set to be available in Q3).

    Well, I'll's a monitor with Pythagorean triple dimensions. Meaning the diagonal is a whole number, 4160 to be precise (13x320).

    Well, I should say it's a monitor with Pythagorean triple dimensions that aren't 4:3, obviously.

    All that to find out whether it would work with a 27" 1440p monitor without significant scaling issues (it would).
  • peterfares - Friday, July 21, 2017 - link

    What? Can't you just look at the pixel density to see if it would work with a 27" 1440p without scaling issues? Same density.
  • Old_Fogie_Late_Bloomer - Friday, July 21, 2017 - link

    Lol, welp, I would have sworn that I looked for the density in the article before doing the calculation myself, but there it is, right under my nose..

    Then again, if I'd seen it, I might not have noticed the Pythagorean nature of the dimensions, so whatever...

    FWIW, Amazon actually has the U3818DW in stock for about $130 less than Dell (URL shortened)

    Personally, I will be sticking with my Dell U3415W as it fits my desk nicely and the price was much more reasonable IMHO. I am not sure how popular these larger displays will be as the added size/pixels seems minimal for the price difference:
    Dell U3818DW
    37.5″ 499.26 square inches (34.6″x14.4″) 3840×1600 12:5 110.93 PPI

    34″ 411.76 square inches (31.4″x13.1″) 3440×1440 43:18 109.68 PPI ~$700

    Dimensions/PPI source:

    Anybody out there going to get one of these?
  • DigitalFreak - Monday, July 24, 2017 - link

    I have the U3415W as well. The only thing I wish it had was G-Sync. It launched at around $1200 IIRC (got mine for just under $900 at the time), so I'd guess the price on this one will drop over the next couple of years.
  • extide - Monday, August 21, 2017 - link

    You can simplify it all the way down to 12:5
  • abrowne1993 - Friday, July 21, 2017 - link

    I'd rather just have a 40" 3840x2160 monitor.
  • cekim - Friday, July 21, 2017 - link

    With 120Hz refresh please... 60Hz is all work and no play.

    Ultra wide has a number of advantages in several usage scenarios.
