AI Verdict

Pros
- The 21:9 aspect ratio and 3440 x 1440 resolution provide ample screen space for running multiple applications simultaneously.
- USB Type-C connectivity with 65W power delivery simplifies setup by charging laptops and transmitting video/data through a single cable.
- The monitor covers up to 99% sRGB color gamut, offering accurate colors for general use and content consumption.
- The stand allows for both height and tilt adjustments, enabling users to find a comfortable viewing position.
- Picture-by-Picture (PbP) functionality supports displaying content from two separate input sources simultaneously.
- The 3-side virtually borderless design is aesthetically pleasing and suitable for multi-monitor setups.
Cons
- The 100Hz refresh rate and 5ms GtG response time are not optimized for competitive or high-performance gaming, potentially leading to noticeable ghosting.
- Brightness is limited to 300 nits, which is not particularly bright and won't deliver a truly impactful HDR10 experience compared to higher-end displays.
- The VA panel's 3000:1 contrast ratio, while decent, won't match the deep blacks and infinite contrast of OLED panels.
- The stand lacks swivel and pivot adjustments, limiting flexibility for screen orientation and sharing views.
- There are no built-in speakers, requiring external audio solutions.
Dimension Scores
The 3440x1440 WQHD resolution and 99% sRGB coverage are solid, but the 300-nit brightness and VA panel's contrast, while 3000:1, don't compete with brighter, wider gamut, or OLED displays.
A 100Hz refresh rate is an upgrade from 60Hz, but the 5ms GtG response time is average and can show ghosting in fast-paced content, falling short for serious gamers.
With 2x HDMI, 1x DisplayPort, 2x USB-A, a headphone jack, and a USB Type-C port with 65W power delivery, connectivity is comprehensive for a wide range of devices.
The stand offers height and tilt adjustments, which is better than tilt-only, but the absence of swivel and pivot limits its overall flexibility.
Best For
- Professionals needing extensive screen space for multiple open applications like coding, video editing timelines, or financial charts.
- Users with USB-C compatible laptops seeking a single-cable docking solution for video, data, and power delivery.
- Casual gamers who prioritize immersive visuals over competitive response times and refresh rates.
- Home office setups where a large, curved display can replace a dual-monitor arrangement.
Not Recommended For
- Competitive esports players who require refresh rates above 144Hz and response times below 5ms.
- Professional graphic designers or photographers who need wider color gamuts like DCI-P3 for critical color work.
- Users who frequently need to rotate their monitor to portrait mode or swivel it for collaborative viewing.
Watch Out For
- The 5ms GtG response time on a VA panel can result in noticeable ghosting in fast-moving content, particularly in games.
- At 300 nits typical brightness, the HDR10 support is more of a marketing bullet point than a truly impactful visual feature.
- Some Reddit users reported negative experiences, with one calling it "horrible" and another suggesting VA panels can be "faulty" after a year, though these are isolated incidents.
- The absence of built-in speakers means you'll need to budget for external speakers or headphones.

What Buyers Say
This LG UltraWide monitor is a productivity powerhouse, giving you a ton of screen space that makes juggling multiple windows way easier. Users consistently point out how the 21:9 aspect ratio and 3440x1440 resolution are a game-changer for work, letting them see everything without constantly alt-tabbing. The USB-C with 65W power delivery is a huge win for keeping desks tidy and laptops charged. While the 100Hz refresh rate is a step up from basic monitors, some users noted it's not quite enough for hardcore gaming, and the 300-nit brightness won't blow you away with HDR content.
“Dude, this monitor is HUGE for work, like I can finally have all my spreadsheets open without squinting, and that USB-C cable for my laptop? Genius. But seriously, don't buy this if you're trying to be a pro gamer, the refresh rate ain't it.”
Common Praise
- The 21:9 aspect ratio provides an expansive workspace, making multitasking with multiple windows much more efficient.
- USB Type-C with 65W power delivery is incredibly convenient for connecting and charging a laptop with a single cable.
- The height and tilt adjustable stand allows for finding a comfortable viewing angle during long work sessions.
- The 99% sRGB color coverage delivers accurate and pleasing colors for general use and media consumption.
- The curved display enhances immersion, especially for productivity and casual entertainment.
Common Complaints
- The 100Hz refresh rate and 5ms response time are not sufficient for competitive gaming, leading to potential motion blur.
- Brightness levels at 300 nits don't fully leverage HDR10, making HDR content less impactful than on brighter displays.
- The lack of swivel and pivot adjustments on the stand limits ergonomic flexibility.
- Some users expressed concern about VA panel ghosting in fast-moving scenes.
- No integrated speakers means you need to buy separate audio equipment.
Ownership Tips
- The OnScreen Control software is almost essential for easily managing window layouts and monitor settings without fumbling with physical buttons.
- The curved screen takes some getting used to if you're coming from a flat panel, but it really helps with peripheral vision on such a wide display.
- While it has HDR10, the actual visual difference from SDR is minimal due to the 300-nit brightness.
- The 65W power delivery is enough for most ultrabooks, but some larger or gaming laptops might still need their dedicated charger for full power.
- The 3-side borderless design looks clean, but the bottom bezel is still present and noticeable.
Frequently Asked Questions

What kind of stand adjustments does it have?
The stand allows for height and tilt adjustments, so you can position the screen for comfortable viewing. It does not offer swivel or pivot functionality.
Can I connect my laptop and charge it with one cable?
Yes, the USB Type-C port on this monitor supports up to 65W power delivery, allowing you to connect and charge compatible laptops while also receiving video and data signals.
Is this monitor good for gaming?
For casual gaming, the 100Hz refresh rate and curved display offer an immersive experience. However, for competitive gaming, the 5ms response time and 100Hz refresh rate might not be fast enough, potentially leading to ghosting.
What is the color accuracy like?

Buying Guide
When you're looking at an ultrawide monitor like this, you're buying screen real estate. Think about how many windows you usually have open and if you're constantly switching between them. A curved screen helps keep the edges of such a wide display within your comfortable viewing angle, so you're not craning your neck. Also, check if your computer's graphics card can handle the 3440x1440 resolution without a hitch. If you're planning to use a laptop, USB-C with power delivery is a huge convenience feature.
Resolution (3440 x 1440)
This tells you how many pixels are packed onto the screen. More pixels mean sharper images and more space for your applications, like having two 1440p monitors side-by-side without a bezel in the middle.
Aspect Ratio (21:9)
This is the shape of the screen. A 21:9 ultrawide is much wider than a standard 16:9 monitor, giving you a panoramic view that's fantastic for multitasking or immersive movies, like watching a film in its original cinematic format.
Refresh Rate (100Hz)
This is how many times the screen updates per second. A 100Hz refresh rate means smoother motion than a standard 60Hz monitor, making scrolling and casual gaming feel more fluid, like flipping through a high-quality animation book versus a flipbook.
USB Type-C with 65W Power Delivery
This single port can handle video, data, and power. It means you can connect a compatible laptop to the monitor with just one cable, charging it while extending your display and using the monitor's USB ports as a hub, like a single super-cable for your entire desk setup.
Alternatives
If this monitor doesn't quite fit, look for models with a 144Hz+ refresh rate and 1ms response time for competitive gaming, or displays with DCI-P3 color coverage and higher peak brightness for professional creative work.
