QHD IPS LG UltraWide Ergo 34WN780-B monitor review
The LG UltraWide Ergo 34WN780-B monitor is a game-changer in the world of productivity and entertainment. Whether you’re a professional multitasker or a binge-watching enthusiast, this monitor has something special to offer.
Ergonomic Excellence: First and foremost, let’s talk about the ergonomic design. The “Ergo” in the name is no marketing gimmick; it’s a testament to LG’s commitment to making your workspace as comfortable as possible. This monitor comes with an adjustable stand that allows you to swivel, pivot, and tilt it to your heart’s content. Whether you prefer a portrait or landscape orientation, this monitor will oblige. And if you’re tired of slouching over your desk, you’ll appreciate the height-adjustable stand that can be set to the perfect eye level.

Working long hours? No problem. The LG UltraWide Ergo 34WN780-B has you covered with its eye-care technology. The flicker-free and blue light reduction features help reduce eye strain, allowing you to work or play for extended periods without discomfort. So, whether you’re editing spreadsheets, writing reports, or battling foes in your favorite game, your eyes will thank you for choosing this monitor.
Design: Now, let’s talk about aesthetics. The 34-inch ultra-wide display is a sight to behold. The virtually borderless design offers an immersive experience that draws you into your content. The slim bezels make this monitor look sleek and modern, perfect for any workspace, whether it’s a home office or a dedicated gaming den. The brushed metallic stand adds a touch of sophistication, making it a great fit for any environment.
What truly sets the LG UltraWide Ergo 34WN780-B apart is its attention to detail. Cable management is often an afterthought in monitor design, but not here. The monitor’s stand features a built-in cable management system that keeps your workspace clutter-free. No more tangled mess of cables on your desk!
Performance: Let’s not forget about performance. This monitor boasts a 3440 x 1440 resolution with an IPS panel, delivering vibrant colors and wide viewing angles. Whether you’re editing photos or watching movies, the picture quality is nothing short of stunning. The 21:9 aspect ratio is ideal for multitasking, allowing you to open multiple windows side by side without feeling cramped.

For gamers, the LG UltraWide Ergo 34WN780-B doesn’t disappoint. With a 75Hz refresh rate and 5ms response time, it offers smooth gameplay and minimal motion blur. While it may not be the go-to choice for hardcore esports enthusiasts, it’s more than capable of providing an immersive gaming experience for casual and enthusiast gamers alike.
Connectivity: In the connectivity department, this monitor shines. It comes equipped with two HDMI ports, a DisplayPort, and even a USB-C port. The USB-C port not only allows you to connect your laptop or desktop but also charges your device simultaneously. This feature is a godsend for MacBook users and anyone who values simplicity and convenience.
Additionally, there are two USB 3.0 downstream ports and a headphone jack, making it easy to connect your peripherals and audio devices. The inclusion of a USB hub is a nice touch, reducing the need for additional dongles or adapters.
Rock-Solid Build Quality: When it comes to build quality, LG has hit the mark. The monitor feels sturdy and well-constructed. The stand, in particular, exudes durability, and the adjustability options feel smooth and reliable. LG’s reputation for quality is evident in every aspect of this monitor’s design and construction.
Unique Features: Now, let’s talk about what makes the LG UltraWide Ergo 34WN780-B truly unique. The OnScreen Control software is a standout feature. It allows you to split your screen into multiple sections, making multitasking a breeze. You can customize the layout to suit your workflow, whether you’re a content creator, programmer, or just someone who likes to keep their email and social media open side by side.
Another cool feature is the Dual Controller. If you have two devices connected to the monitor, you can control both with a single keyboard and mouse. It’s incredibly convenient for those who work with a laptop and desktop setup or simply want more screen real estate for different tasks.

We were impressed by the versatility of its adjustable arm, which offers an impressive 130mm of height adjustment, a generous 25-degree tilt range, and an impressive 280 degrees of swivel. Getting comfortable with this monitor is a breeze, making it a fantastic fit for virtually any workspace. The arm itself feels robust and sturdy, perfectly suited for supporting the expansive 34-inch ultrawide panel.
LG has made a concerted effort to maximize the versatility of this monitor, a noteworthy endeavor considering its IPS panel, which delivers excellent viewing angles, and a 75Hz refresh rate for smoother on-screen motion. The port selection is commendable as well, featuring a couple of USB-A ports, DisplayPort, and HDMI connections, all conveniently facing outward for easy access. Priced at £509.99, it strikes a reasonable balance between features and cost.
Integrated stereo speakers, while not audiophile-grade, are a welcome addition on this monitor, sparing you the hassle of setting up separate speakers. Their sound quality may not blow you away, but they get the job done. Another noteworthy feature is the dedicated Reader Mode, which reduces blue light emission, ensuring a gentler experience for your eyes during those late-night sessions.
However, the true star of the show here is the ingenious arm mount. It securely clamps to your desk and provides exceptional flexibility in positioning the screen. You can effortlessly swing it into view when you need it and tuck it away when you don’t. While some users may prefer a more traditional stand, this mount design is a game-changer, and it keeps your desk free from clutter.
Cable management is a thoughtful touch, simplifying the organization of your cables. Moreover, the monitor offers a variety of ports at the back: two HDMI ports, a DisplayPort socket, a USB-B upstream port, and two USB-A downstream ports, effectively transforming the monitor into a convenient USB hub for your various devices. Additionally, there’s a headphone port for your audio needs.
Setting up the monitor is a straightforward process, although you might want a helping hand to get it connected and properly positioned, given its flexible arm. The on-screen display provides intuitive control over essential settings like brightness, contrast, and volume. For content or devices that don’t support the 21:9 aspect ratio, you have the option to stretch the image to fit or maintain its original dimensions, with black bars on the sides. This flexibility ensures compatibility with a wide range of content and applications.
The LG UltraWide Ergo 34WN780-B is a top-tier monitor that excels in ergonomic design, aesthetics, performance, connectivity, and build quality. It’s a versatile workhorse that can enhance your productivity and entertainment experiences. Whether you’re working from home, gaming, or simply enjoying multimedia content, this monitor is a worthy investment that will elevate your computing setup to a whole new level of comfort and functionality. Say goodbye to neck strain and hello to ergonomic bliss with the LG UltraWide Ergo 34WN780-B!
