Overview

The LG UltraGear evo AI 27GM950B-B is a 27-inch gaming monitor that pushes boundaries with a 5K (5120×2880) resolution and Hyper MiniLED backlighting. Its IPS panel covers 99% of DCI-P3 and holds VESA DisplayHDR 1000 certification, making it equally suited for creative work and high-end gaming. The standout feature is VESA Dual Mode, which lets you switch between 5K@165Hz and WQHD (2560×1440)@330Hz on the fly. With a 1ms GTG response time, the monitor delivers crisp motion clarity. The USB-C port supports 90W Power Delivery, allowing you to charge a laptop while transmitting video. It also includes DisplayPort 2.1 and HDMI 2.1 inputs, ensuring compatibility with the latest graphics cards.

Connectivity & Compatibility

Video inputs include DisplayPort 2.1 (one), HDMI 2.1 (one), and USB-C (with PD 90W). DisplayPort 2.1 handles 5K@165Hz at full bandwidth, while HDMI 2.1 can drive WQHD@330Hz. The USB-C port simplifies desk setups by combining video and charging in one cable. The monitor supports VESA 100×100mm mounting and comes with a height-adjustable, pivot, tilt stand. Two USB 3.0 downstream ports are available on the rear for connecting peripherals.

Product Info

Released in late 2025, the 27GM950B-B is available in Japan through retailers like . It sits in the premium price bracket, around ¥197,000, with few direct competitors in the 27-inch 5K Hyper MiniLED category. LG offers a standard 3-year warranty (extendable to 4 years with registration). Included accessories: power cable, DisplayPort cable, USB-C cable, and quick setup guide. Market positioning: a high-end dual-purpose monitor for gamers and creators. While 4K@240Hz panels exist at similar prices, the 27GM950B-B's unique 5K resolution and 330Hz WQHD mode give it a distinct advantage for users who want both pixel density and extreme speed.

Best Use Cases

For creative professionals: the DCI-P3 99% coverage, HDR1000 brightness, and hardware calibration support make it an excellent choice for photo and video editing where color accuracy is critical. For gamers: those who appreciate stunning visuals in RPGs and open-world titles at 5K, and also want the option to switch to a blistering 330Hz for competitive shooters. The 1ms response and FreeSync Premium Pro (G-SYNC Compatible) ensure tear-free gameplay. However, driving 5K at high refresh rates requires a DisplayPort 2.1-capable GPU (e.g., RTX 40-series or newer). Budget-conscious users who don't need 5K may find better value in 4K@240Hz alternatives.
