LG UltraWide Ergo 34WN780-B Useful Review

LG UltraWide Ergo 34WN780-B Review

The LG UltraWide Ergo 34WN780-B is a widescreen monitor that deviates from the standard design. LG’s gadget, on the other hand, features a fantastic ergonomic arm that provides amazing adaptability. In fact, the ergonomic arm provides more mobility choices than other business screens, which is especially useful in a small workplace or if you work from home.

LG UltraWide Ergo 34WN780-B Review

The 34WN780-B is impressive, but it is not inexpensive. It costs £425 in the UK at the time of writing, although it frequently costs £500 or more. Expect to pay $591 in the United States. It is available for €528 in Europe.

That’s a little pricey for a 34-inch widescreen with this quality; the only more costly monitors at this size and resolution are often bombastic gaming displays rather than work screens.

Design and features

LG UltraWide Ergo 34WN780-B Review: Back
  • A fantastic, ergonomic stand
  • A widescreen format that is useful for everyday chores.
  • Internal specifications are middle-of-the-road, but they don’t go much farther.

Instead of a typical base, the LG UltraWide Ergo 34WN780-B’s ergonomic arm clamps to your desk. This is perfect for saving space, and the clamp is straightforward to use – it’s broad and quick to attach, and it has a rubberized covering that increases grip and protects the surface.

The ergonomic arm has a wide range of motion once it’s mounted to your desk. It can swivel a whopping 280 degrees and extend or retract by 180mm. It also has a 25-degree tilt and a 130-mm height adjustment. In most cases, the arm glides easily; only the height adjustment is stiff.

LG UltraWide Ergo 34WN780-B Review: 100mm VESA mounts

The LG also supports 100mm VESA mounts, however if you’re not going to utilise the ergonomic arm, a 34in widescreen with a traditional base might be a better choice. Fortunately, if the clamp is correctly set, the arm feels substantial and firmly supports the panel, and the display itself is as sturdy.

The clamp contains adjustable screws that secure the LG to various desk widths. It’s a clever solution, but keep in mind that the clamp must be securely fixed to your desk in order to hold the display in place; otherwise, the display may wobble dramatically. For the LG to fit correctly beneath your desk, you’ll need at least 75mm of clearance.

There’s more flexibility here than on any other monitor, which makes the LG excellent for adding adaptability to your work environment – or simply saving space. In the middle strut, there’s also a concealed cable management compartment to make things even neater.

The 34-inch display features a 21:9 aspect ratio and a 3440 x 1440 resolution. It’s almost as large as two 1080p monitors and has more vertical pixels than a conventional Full HD panel. If you’re having trouble with one monitor or want to replace an old dual-panel arrangement, the LG is an excellent choice because it has superior uniformity and no extraneous bezels.

If you work in creative programmes with horizontal timelines, a widescreen makes sense, and it also helps with multitasking.

LG UltraWide Ergo 34WN780-B Review: sRGB Color Gamut

The LG’s internal specifications are adequate, but its display isn’t designed for folks who want excellent image quality for color-sensitive tasks. It’s an IPS panel, but instead of 10-bit colour, it employs 8-bit colour, rendering 16.7 million hues instead of over one billion. While LG promises to follow the sRGB colour gamut, it makes no assurances concerning the Adobe RGB or DCI-P3 colour spaces. Despite having HDR10 capabilities, it isn’t bright enough for HDR content.

Aside from that, the 75Hz frame rate and AMD FreeSync ensure smooth daily motion and movement, but it’s only a small improvement over 60Hz; it doesn’t push any boundaries.

The LG focuses on practicality in other areas. The right-hand side of the screen features an on-screen menu with all of the typical choices, and the centre joystick allows for easy operation. The different picture-in-picture and picture-by-picture settings may be be tweaked with a Windows software.

LG UltraWide Ergo 34WN780-B Review: Two USB 3.2 Gen 1 Ports

There are two USB 3.2 Gen 1 ports on the back, as well as a DisplayPort socket and two HDMI connectors. They’re all facing outwards, making them more accessible. The feature set is completed by a pair of 7W speakers that provide adequate sound quality for casual movie viewing and background music.

Although the design is amazing, several details are lacking. If you work in color-sensitive applications, you’ll want greater colour reproduction on the inside, and USB-C with power supply would be excellent on the outside. It’s also worth noting that this display isn’t curved.

Image quality

  • For everyday use, mediocre contrast levels are sufficient, but there isn’t much depth.
  • Due to an incorrect colour temperature, the colours appear a little washed out.
  • If you need a screen for picture editing or design work, search elsewhere.

The LG UltraWide Ergo 34WN780-B’s brightness level is 231 nits with factory settings, which is adequate for any business. The black point is 0.27 nits, which is average. The resultant contrast ratio of 856:1 is also mediocre, but this isn’t a major flaw: this panel lacks a little depth, but this isn’t a deal-breaker for most productivity apps.

LG UltraWide Ergo 34WN780-B Review: Delta E Color Combination

Although the average Delta E of 0.97 is outstanding, the colour temperature of 7470K is off and cold. The LG displays the sRGB gamut with coverage and volume levels of 97.6% and 102.5 percent, respectively, which are respectable results, but in the Adobe RGB and DCI-P3 regions, it only managed 70.2 percent and 72.6 percent.

These benchmark data cast doubt on the excellent Delta E figure. Colors are a little faint due to the colour temperature. Because of its lack of gamut and reliance on 8-bit colour, this display can only produce a limited range of colours.

Colors are still decent, with enough accuracy to handle mainstream photographs, online browsers, and programmes, and there’s still enough depth and nuance, despite the average colour results and somewhat low contrast.

The LG’s image quality is average, and its uniformity is average. While the display’s top and right sides stayed steady, the panel’s bottom-left and right corners lost roughly 20% of their backlight power. This won’t be visible in ordinary chores, but it’s another indicator that the LG isn’t suited to jobs that need precision and regularity.

Also, don’t hold your breath for the LG’s alternative screen modes. It lacks work-specific choices, and its Vivid and HDR Effect settings degrade the colour temperature, contrast, and Delta E results of the display.

LG UltraWide Ergo 34WN780-B Review: 34 inch Screen

Because of the LG’s benchmark flaws, this display lacks the depth, colour capability, and accuracy of panels built for color-sensitive tasks like picture editing and design.

However, this isn’t always a drawback: the LG UltraWide Ergo 34WN780-B focuses on adaptability, and it succeeds in doing so while providing enough quality for everyday tasks. Given its ergonomic capabilities and dimensions, it justifies its somewhat higher price, especially if you desire a tidy desk or need to preserve space.


The LG UltraWide Ergo 34WN780-B boasts a fantastic, ergonomic design and a form factor that works well in regular work circumstances, as well as a number of other useful features. However, it is more expensive than a standard widescreen and can only give mediocre image quality.
