While 21:9 displays have never caught on for TVs, they seem to have found a niche with computers. Now most vendors have at least one 21:9 display, and at CES this year we saw larger, higher resolution 21:9 panels introduced. All of these panels are aimed at consumers so far, with an emphasis on integrated audio, multiple video inputs, MHL, and other consumer features. Because of this it isn't a surprise that the 21:9 display from NEC is also consumer focused, but let's see how it performs.

The EA293WMi is a 21:9 monitor with 2560x1080 resolution. As with all the 21:9 displays so far, the backlight is an edge-lit white LED that provides the sRGB color gamut but not AdobeRGB. I asked NEC what their target audience is with the 21:9 aspect ratio, as figuring that out has been somewhat challenging.

As I expected, their main target is people that want a display that multitasks between computer and movies or games. For people that watch a lot of films that are shot in the 2.39:1 aspect ratio (which is around half of the movies released each year), the 21:9 aspect ratio allows you to watch those films without black bars at the top. As someone that has a 2.40:1 projection system at home, I understand the desire to watch films without any letterboxing.

Another target that I was unaware of is medical imaging. For lots of medical imaging, people are still using a pair of 19", 4:3 displays to view content. A 29" 21:9 monitors provides a near direct drop-in replacement for those two displays as you can't really purchase them anymore. The NEC contains a DICOM (Digital Imaging and Communications in Medicine) mode, specifically targeting this use case. This is not a use that I, or most people, would likely be aware of but it does help to explain where 21:9 displays will fit in.

Most of the 21:9 monitors on the market have been more concerned with looks over usability. They have nice, thin profiles but lack height adjustments or VESA mounting holes on the back. They look stylish but if you want them at any other height you'll need to place them on top of something. Additionally if you want to use them in portrait mode, where their extra height can be a useful feature, you are going to need to come up with a complex system of mounting it to something. This lack of adjustments is a pet peeve of mine, so I'm happy to report that NEC doesn't restrict their display in this way.

The stand included with the EA294WMi offers both height adjustments and the ability to rotate into portrait mode. There are also VESA mounting screws on the back so you can use your own stand if you desire as well. Even with their consumer line NEC still keeps more focus on ergonomics and usability than looks, which I admire. It also offers full tilt and swivel ability making the stand very versatile.

The EA294WMi is well stocked with inputs: DisplayPort, HDMI/MHL, Dual DVI (only one is Dual Link), and dual DSub mean that anything you want to connect should be possible. There is a 4-port USB hub that is integrated as well but it is only USB 2.0. Unlike the professional displays you can’t use the EA294WMi as a KVM for two computers.

The on-screen display is reminiscent of the professional line but is more consumer focused. Brightness levels are indicated in percent instead of cd/m^2 and there are fewer preset modes to select from. It still provides more flexibility than most displays but not the granular ability found on professional NEC models. The menus are fairly easy to control as button labels pop up on the screen. I’d prefer a 4-way control, or all the controls to be along the same side of the display, but all the required features are at least present.

NEC provides a few features specific to their displays here. One is a human presence sensor that detects if someone is sitting in front of the display or not. If you are absent for a set time period it can dim the display to conserve energy. Many of us just use the power management in our OS to accomplish this, but in case that fails (and Windows has a habit of just turning back on I find) this is a backup. You can also daisy-chain NEC displays together with a 3.5mm cable and have a master control the other units. If you often make adjustments to brightness or other controls this can be handy, but you need a full array of displays from NEC for it to work.

    Ever since moving to 1440p sometime back I wont go back 1080p...is just old now..the only trhing imo holding back 1440p from being mainstream is the fact that you need a HPU to use it as the intel igpu is crap and same witht he amd....

    keep hearing about 4k this and that yet most don't even understand those craphole panels only do 30hz lol people are skipping and thinking they can go straight to 1080p to 4k over the next year or two.....nope not gonna happen get yourself a good 1440p Korean pnael or even two and be set...don't wait for crappy slow manufactuare to release some overpriced non sense like Asus is doing with the 1440p AOG crapy TN panels and ripping everyone a new one lol 1080p trash

    Almost twice the cost of the under-rated AOC Q2963OM

    You mixed up the contrast ratio chart- it's 989:1 at max brightness, and 838:1 at minimum brightness, not the other way around.

    Where are the LESS wide-aspect displays? I want a nice 16:12 3200x2400 display.
  • ShieTar - Tuesday, February 18, 2014 - link

    16:12 is 4:3. Thats not less wide, its legacy.
  • Hrel - Monday, February 10, 2014 - link

    We don't need wider displays. We need Hollywood to stop making things wider for NO FUCKING REASON AT ALL!!!!! If you can't fit the shot in a 16:9 frame back up, or stop sucking so hard at your profession.
  • extide - Monday, February 10, 2014 - link

    The sad part is, if you notice, in basically anything shot wide (or super wide) the 'important stuff' is all within a 4:3 box in the center, so it can still be viewed on a 4:3 screen properly. Ever notice when you watch the news on widescreen, the news logos in the corner aren't in the far corners, they are in a bit? That is because they are at the edges of where a 4:3 screen would be! So the edge space is all basically wasted!

    There's actually a very good reason movies are shot in widescreen resolutions. It's the same reason people generally do multi-monitor setups that extend horizontally, rather than stacking two or three monitors vertically. Think about it.

    A 21:9 monitor like this is a great alternative for a multi-monitor setup for those who don't want to deal with the headaches and bezels.

    For years, people put two 1280x1024 monitors next to each other. Then 1080p screens show up and it becomes a fucking meme to pretend you're a "professional" who can't work with anything less than 1200p.

    So 1440p becomes affordable and people still play this frickin' meme, because 16x9 is the "Devil's AR".

    Except 16:9 was picked as a compromise aspect ratio for everything. Academy Ratio (1.37:1) content can fit windowboxed, Scope content(2.39:1) can fit letterboxed, and flat (1.85:1) content will fit almost perfectly. 16:9 wan't created to eliminate choice in aspect ratios, but to provide a good format for all of them. I shouldn't foget 70mm (2.20:1) in here either.

    Also, I'd like to let artists pick how they want to present things. If they want to use Academy, or Scope, or Flat, that's their choice. The idea that they don't know what they're doing by shooting scope is just laughable as well.
