LG's 39GX950B has officially launched in the United States with a price of $1,800 (€1,656), marking the arrival of the world's first 39-inch ultrawide OLED monitor with a 5120 x 2160 resolution. The UltraGear evo GX9 features a 4th generation Tandem WOLED panel with a 1500R curvature, 165Hz refresh rate, and a dual-mode option that switches to 330Hz at WFHD resolution. The monitor delivers 335 cd/m² brightness in SDR, 0.03 ms GtG response time, and VESA DisplayHDR True Black 500 certification with 99.5% DCI-P3 color gamut coverage.
The 39GX950B includes built-in AI upscaling that enhances content to match the 5K2K resolution without requiring GPU processing, a notable feature for the UltraGear evo lineup. Connectivity options include one DisplayPort 2.1 port with full bandwidth support, two HDMI 2.1 ports, and a USB Type-C port with 90W power delivery. For Linux users, the monitor's DisplayPort 2.1 implementation arrives as kernel support matures, with Linux 6.14 adding UHBR modes for Ultra-High Bit Rate DisplayPort over Thunderbolt on Intel Panther Lake platforms, while Intel engineers continue work on USB-C DP 2.1 Alternate Mode support and AMD has submitted patches for Radeon GPU DisplayPort 2.0 compatibility. The monitor supports both NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro for variable refresh rate gaming.
The LG product page is now live in the US, with the monitor also appearing on Amazon at the same $1,800 (€1,656) price point, though currently out of stock. In Canada, the LG Canada product page indicates pre-orders begin 2026-04-17, while Japan's LG page suggests reservations start 2026-04-09. Availability dates vary by region, with most markets expected to receive stock between late April and May 2026.
