When it comes to high-quality displays, LG monitors are often at the top of the list for many professionals and gamers. Two popular options from LG are the 27UL850-W and the 34GN850-B. While both monitors offer impressive features, they cater to different needs and preferences. In this comparison, we'll delve into the details of each model to help you decide which one is best for your specific requirements.

Display Size and Resolution

The most obvious difference between the two monitors is their display size. The LG 27UL850-W features a 27-inch screen, while the LG 34GN850-B boasts a larger 34-inch display. In terms of resolution, both monitors offer high-definition displays, but with different pixel densities. The 27UL850-W has a 4K UHD (3840 x 2160) resolution, resulting in a pixel density of approximately 163 pixels per inch (PPI). On the other hand, the 34GN850-B has a QHD (3440 x 1440) resolution, which translates to a lower PPI of around 109.

Aspect Ratio and Curvature

The aspect ratio of both monitors differs, with the 27UL850-W featuring a traditional 16:9 aspect ratio, while the 34GN850-B has a wider 21:9 aspect ratio. The latter is ideal for multitasking, gaming, and cinematic experiences. Additionally, the 34GN850-B features a curved display (3800R curvature), which can enhance immersion and reduce eye strain. In contrast, the 27UL850-W has a flat panel.

Refresh Rate and Response Time

For gamers and fast-paced content enthusiasts, refresh rate and response time are crucial factors. The LG 34GN850-B has a higher refresh rate of 160Hz (overclockable to 180Hz), making it more suitable for smooth motion and reduced screen tearing. In contrast, the 27UL850-W has a lower refresh rate of 60Hz. However, both monitors feature a fast response time of 1ms (GtG), which helps minimize ghosting and blurring.

Color Accuracy and HDR Support

Both LG monitors are known for their excellent color accuracy, with the 27UL850-W covering 98% of the DCI-P3 color gamut and the 34GN850-B covering 95%. However, the 27UL850-W has a slightly higher contrast ratio (1000:1) compared to the 34GN850-B (800:1). In terms of HDR support, both monitors feature VESA DisplayHDR 400 certification, but the 27UL850-W also supports Dolby Vision.

Connectivity and Ergonomics

In terms of connectivity, both monitors offer a range of ports, including USB-C, HDMI, DisplayPort, and USB-A. However, the 34GN850-B has an additional headphone jack and a more comprehensive set of gaming-oriented features, such as NVIDIA G-Sync compatibility. When it comes to ergonomics, both monitors feature adjustable stands with tilt, height, and pivot adjustments, but the 34GN850-B also allows for swivel adjustment.

Conclusion

When choosing between the LG 27UL850-W and the LG 34GN850-B, consider your specific needs and preferences. If you prioritize a compact design, high pixel density, and excellent color accuracy, the 27UL850-W might be the better choice. On the other hand, if you prefer a larger, curved display with a higher refresh rate and more comprehensive gaming features, the 34GN850-B is likely the way to go. As part of the esteemed lineup of LG monitors, both options offer exceptional performance and value, making either one a great investment for professionals, gamers, and entertainment enthusiasts alike.
