NEC MultiSync® EA Series

High-Performance , LED-Backlit LCD
Ideal Displays for Corporate Environments


Reimagine Your Desktop Computing Experience

With its 4th generation MultiSync EA Series, NEC has developed monitor solutions that push the boundaries of what you've come to know as business-grade screen performance. The 22" EA224WMi, 23" EA234WMi, 24" EA244WMi, 24" EA244UHD, 27" EA274WMi, 29" EA294WMi, and 30" EA304WMi deliver a completely redesigned chassis with a host of enhanced features, advanced technologies, future-proof connectivity and environmentally friendly benefits. Select models tout an IPS module, which boasts the best possible color accuracy and minimal viewing angle shift.

These models boast LED backlight technology, which not only reduces power by up to 52% compared to their predecessors, but leads to a 30% thinner and 25% lighter chassis. Other green features include ECO Mode™, a carbon footprint meter and an ambient light sensor, which automatically adjusts the brightness to the optimal setting depending on ambient lighting, screen content or both, conserving power up to 87% compared to typical energy consumption. In addition, the human sensor detects user activity in front of the monitor and reduces display power up to 95% with inactivity.

The ground breaking ControlSync™ feature allows users to control up to six select MultiSync EA Series units in a multi-monitor configuration. Upon establishing one unit as the master, you will be able to simultaneously control many performance attributes of the multi-monitor setup through the master monitor.


  • LED backlight technology provides industry-leading, low-power consumption and less hazardous materials
  • Four-way ergonomic stand boasts pivot, tilt, swivel and height adjustment up to 5 inches (130mm) to maximize your viewing comfort
  • Touch-sensitive OSD® controls are integrated into the bezel, making display adjustments easier than ever
  • Integrated USB hub easily connects you to your peripherals
  • Comprehensive input panel, including DisplayPort, HDMI, DVI-D and 15-pin VGA (on select models), connects you to the latest peripherals and future-proofs your investment
  • Space-saving, multimedia speakers, which enhance your computing experience, are hidden to maintain the monitor's aesthetic appeal (headphone jack also included)
  • ControlSync enables multi-monitor setups of up to six monitors and controls up to 26 settings
  • Customize Setting allows both users and IT administrators to set and restore preferred settings with just one touch, contributing to a free-seating business environment
  • Smart sensing technology includes ambient light and human sensors, which considerably reduce power consumption by automatically detecting your work conditions and adjusting to the proper display brightness or entering Power Saving Mode
  • Carbon footprint meter helps track and calculate the reduction of green gas emissions, while the resettable cost meter (via On Screen Display) indicates electricity cost savings based on currency settings
  • NaViSet™ software offers an intuitive graphical interface, allowing for easy adjustment of display settings via mouse and keyboard. NaViSet Administrator provides all the advanced control to remotely located IT professionals.
  • EPEAT Gold compliance ensures the displays reduce hazardous waste and electricity usage, resulting in lower energy costs and increased protection for the environment
  • ENERGY STAR® compliance reduces electrical costs and lowers total cost of ownership

4 out of 5 eggsExcellent Display, with Some Quirks

Pros: - Picture quality is excellent
- Very light, great for use with a monitor arm
- Included monitor stand is superb; easy to adjust and sturdy
- Two VESA mounting positions (high and low)
- Tons of inputs and a 4-port USB hub
- Great menu interface
- Runs very cool; Heat is hardly noticable next to my old LCD display which doubles a hand warmer.

Cons: - DisplayPort glitch causes the monitor to wake up very frequently (every 2 to 15 minutes) at random when in sleep mode and connected via DisplayPort (AMD and NEC have not been able to resolve this problem); Workaround is to connect via any other source.
- My HDMI port is a little loose and falls out easily if cable is not secured.
- Monitor device disappears from system when turned off and connected via DisplayPort, and reappears when turned back on.
- DisplayPort cable not included; just HDMI and VGA
- Left edge USB ports not ideal when positioned on the right in a dual monitor configuration.

Other Thoughts: - USB ports turn off when the monitor is turned off; This is nice if you don't connected storage or other always-on devices to it (e.g. mice, keyboards).
- Touch controls are easy to bump when adjusting the display on a monitor arm.
- Barring the DisplayPort issue, I really love the display, but I wouldn't vote for this if you're committed to using it for the DisplayPort connection.
- Disappointed in NEC's attention to this issue. I have reached out to them about this and they have left it up to me to diagnose my problem. While I have expert-level knowledge of computers, I don't have the time or ability to diagnose electrical/driver type problems that are this minute.

5 out of 5 eggsSolid panel

Pros: - Uses the more common RGB pixel layout
- HDMI & DisplayPort inputs, which is surprisingly hard to find on other monitors
- Lots of adjustments can be made (e.g. turning down the power LED's brightness)
- Matte bezel
- Tech support was knowledgeable and prompt (see other thoughts below)
- Speakers accept input over DP and HDMI
- Human sensing worked surprisingly well when I tested it
- Power consumption is on par with my other 23" IPS panel
- Has standard VESA mount capability

Cons: - Monitor needed calibration to get the colors right. The built in settings on the monitor are not enough, as those provide only linear adjustment. I used a device that sits on the monitor to create an ICC profile, and things look very good once calibrated.
- Viewing angle, while much better than a TN panel, isn't quite as good as some other IPS displays I've seen
- Default contrast is fairly low (compared to what my calibration device recommended), but can be bumped up in the settings
- Speakers aren't amazing, but will work in a pinch or in lieu of desktop speakers if you need space
- Theoretical privacy issues aside, if you want to use the "Human sensing" feature of the monitor, you will see a faint red light near the bottom center of the monitor
- Though not an issue for me (as I'm not using its USB hub), the USB ports on the left are blocked by my secondary monitor. Consider this if you're using two monitors and want access to all the USB ports.

Other Thoughts: I run dual monitors, and this is paired with my Dell U2312HM. I originally bought a P2314H to replace an old TN panel that the U2312HM was previously paired with, However, the P2314H I received had a BGR pixel layout, and ClearType text will not work properly in GDI applications on all monitors if the pixel layout is different.

Ultimately I returned the newer Dell monitor as I found non-ClearType text more fatiguing to read. After contacting NEC's tech support, they informed me that this panel was RGB, and sure enough, when it arrived, it was.

Despite the cons I still consider it to be a very good IPS panel, as they are mostly minor, can be resolved, or not an issue for everyday viewing/use. Also, the buttons are not physical buttons, but capacitive, though each have their tradeoffs and it really comes down to personal preference.

Lastly, I can't speak to the quality of the stand, as I put it in my dual monitor stand immediately. However it looks to be very well thought out in regard to cable management. Additionally, I am not using the built in USB hub, so I cannot judge its quality/functionality.

5 out of 5 eggsGreat Upgrade

Pros: Great color and easy to set up. Impressive improvement in games like Skyrim and Deus Ex Human Revolution. Much better color than previous 19" generic wide screen. Includes all needed cables including several different power cords.

Cons: Printed manual was in Russian.

Other Thoughts: I am running this on a GTX 760 video card on ultra settings and love the difference. I hope this one lasts as long as my previous NEC monitor, a 4D CRT that I had for over 10 years.

5 out of 5 eggsPerfect

Pros: Bright, easy setup, dependable

Cons: A bit pricey, but worth it

Other Thoughts: I have three of these. I bought the first one a couple of years back after having a couple of other brands either have pixels in key areas die off, ballast go out, or just completely die. I got tired of troubleshooting broken monitors. So far the first one and its two younger (two months back) siblings are trouble free.
