The LG 27GL850 and 27GN800-B have similar features. They are both black monitors with matte plastics for the bezel, arm, and base. The LG model has a red trim around the top and bottom edge, and a black panel edge. The 27GL850 has a more convenient stand that has a few more adjustment options. It also has two USB 3.0 ports.
Both monitors offer high-refresh rates. The LG model offers a refresh rate of 144Hz and adaptive-sync support. This means it can cope with NVIDIA G-sync and AMD FreeSync systems. It also has NVIDIA certification, ensuring decent VRR performance. It is a very good choice if you need a gaming monitor and a fast refresh rate.
The LG 27GL83A offers a wide 178-degree viewing angle, 10 bits of color depth, and a 1ms response time. It also offers 1440p resolution and 350-nit peak brightness. Like the LG 27GL850, the 27GL83A has a high sRGB color gamut. Hence, it’s suitable for entry-level color-critical work.
The 27GL850 is also a good choice for gamers. It offers good connectivity, with two HDMI ports and one DisplayPort 1.4. DisplayPort is the standard connection for PCs, but HDMI supports connections from gaming consoles and other external devices. Both HDMI and DisplayPort support variable refresh rates, which is useful for AMD and some games consoles.
When it comes to gaming, the LG 27GL850-B has a higher refresh rate (144 Hz). The higher the refresh rate, the more smooth animations will be. However, high refresh rates require a better graphics card. A 120 Hz monitor only works with a 120 fps graphics card.
