Don’t confuse it with the 5K2K 45GX950A-B
LG’s official US page is for the distinct 45GX950A-B, not the 45GX900A-B in the deal. LG lists the 45GX950A-B at 5K2K resolution (5120 × 2160), with selectable refresh-rate modes of 165Hz or 330Hz. Its December 2024 announcement for the GX9 family describes the 45GX950A as a 45-inch 21:9 5K2K OLED monitor and lists DisplayPort 2.1, HDMI 2.1, and USB-C with 90W power delivery. Those are specifications for the other model and should not be attributed to the deal monitor.
