Don’t confuse it with LG’s 45GX950A-B
LG’s 45GX950A-B is a separate 45-inch UltraGear OLED model, not the monitor named in this deal. LG lists its resolution as 5K2K (5120 × 2160) and its dual refresh-rate modes as 165Hz or 330Hz on the official US product page. LG’s GX9 announcement also identifies the 45GX950A as a 5K2K display and specifies DisplayPort 2.1 and USB-C with 90W power delivery. See LG’s December 2024 announcement.
Those 5K2K resolution, refresh-mode and 90W USB-C details should not be attributed to the deal’s 45GX900A-B. The official LG sources cited here describe the other model and do not independently confirm the 45GX900A-B’s specifications.
