LG Canada shares details of the world's first 39-inch 5K2K OLED gaming monitor with AI upscaling without a GPU

The much-anticipated LG 39GX950B has appeared on LG's website in select regions. LG presents it as the world's first 39-inch 5K2K gaming OLED monitor with AI upscaling. The screen debuted at CES 2026 in January, with a late-April launch window, and is now listed on LG Canada's store, giving us a more detailed look at its specifications.

The 39GX950B features a 38.86-inch 21:9 OLED panel with a resolution of 5120 x 2160 and a pixel density of 143 PPI. The screen curves at 1500R, which is much less aggressive than the 800R curve on LG's other ultrawide OLED monitors. Under the hood, it is built around a 4th Gen Tandem WOLED panel with a typical SDR brightness of 335 cd/m², 10-bit color, and 99.5% DCI-P3 gamut coverage.

For gaming, the monitor offers a 165Hz refresh rate and a dual-mode feature that boosts it to 330Hz at 2560 x 1080. It features a 0.03ms G2G response time, VESA DisplayHDR True Black 500 certification, FreeSync Premium Pro, G-SYNC Compatible support, and VRR.

The surface treatment is anti-glare with low reflection, though a glossy version is available for other monitor manufacturers to adopt. On the connectivity side, you get one DisplayPort 2.1 port, two HDMI 2.1 ports, a USB Type-C port with DP Alt and 90W power, two USB-A data ports, and a headphone jack. PiP and PbP modes support multiple inputs simultaneously.

The AI features built into the display itself are also a nice touch. LG says its internal processor handles 5K2K AI upscaling without requiring additional GPU power. The AI package also includes AI Sound, which separates voices, effects, and background audio into a virtual 7.1.2-channel experience through the monitor's 7W x2 speakers or headphones. AI Scene Optimization automatically adjusts color temperature, sharpness, and enhancement based on the content type.

That said, pricing remains unknown, and launch dates for most regions are still unconfirmed. The LG Japan page suggests that reservations will begin on 9th April in that region. We will share more details as they become available.
