Review

The LG 45GX950A-B is a 44.5-inch OLED gaming monitor designed for users who need both high resolution and extreme speed. Its standout feature is the VESA Dual Mode, allowing seamless switching between 5K2K (5120×2160) @165Hz for cinematic graphics and WFHD (2560×1080) @330Hz for fast-paced FPS games [S1]. Users can also adjust the effective screen size from 44.5 inches down to 24 inches and choose between 21:9 and 16:9 aspect ratios [S1]. Visually, the monitor utilizes Micro Lens Array (MLA) technology to achieve a peak brightness of 1300cd/㎡ (at APL 1.5%), complementing the near-perfect blacks inherent to OLED [S1]. A response time of 0.03ms minimizes motion blur for crisp action [S1]. Connectivity is modernized with DisplayPort 2.1 (UHBR13.5), featuring Forward Error Correction (FEC) to reduce noise and data errors [S1]. It also supports USB Type-C with power delivery up to 90W [S1].
