Please review all product photos before purchasing. 45" Curved OLED · Anti-Glare · 20W Speakers · webOS + Remote · USB-C 65W · Built-In LAN The 45GX90SA-B is the version of the UltraGear OLED lineup that doesn't require a separate speaker bar, soundbar, or streaming stick to be genuinely useful as a living room gaming or home theater display. The webOS smart platform — the same OS used in LG's premium TVs — gives this monitor direct access to Netflix, Disney+, Prime Video, and cloud gaming services without a PC, and the Magic Remote in the box makes navigating it feel like a TV. The 2×10W built-in stereo speakers are substantial for a monitor and adequate for casual gaming and streaming without an external sound system. On the PC side, the connectivity is unusually complete: USB-C carries 65W power delivery plus DisplayPort signal — a single cable charges a laptop while connecting it as the display source. A built-in RJ-45 LAN port provides wired network connectivity without a hub or adapter — useful for both the webOS smart features and low-latency PC gaming. The anti-glare matte coating manages ambient light well without the saturation penalty of some anti-reflective treatments. The 800R curvature is the steepest mainstream curve available — noticeably more immersive than 1800R alternatives at 45", wrapping the edges of the 21:9 field into peripheral vision. 3440×1440WQHD 21:9 240HzRefresh Rate 0.03msGtG Response 20WStereo Speakers 800RCurvature 🔌Ports & Connectivity 📺 HDMI 2.1 ×2 4K@120 · VRR · eARC 🖥 DisplayPort 1.4 WQHD@240Hz 🔌 USB-C 65W PD · DP Alt · Data 🌐 LAN (RJ-45) Built-In Ethernet 🔷 USB-A ×2 USB 2.0 Hub 🎧 Headphone Out 3.5mm 📋Specifications PanelOLED (3rd Generation) · Anti-Glare matte coating · 800R curvature Screen Size44.5" (marketed as 45") Resolution3440 × 1440 — WQHD · 21:9 aspect ratio Refresh Rate240Hz Response Time0.03ms GtG Brightness1,300 cd/m² peak HDR (MLA) · 275 cd/m² typical SDR Contrast1,500,000:1 (OLED true black) Color98.5% DCI-P3 · 10-bit · 1 billion colors HDRDisplayHDR True Black 400 · HDR10 · HLG Variable RefreshNVIDIA G-Sync Compatible · AMD FreeSync Premium Pro · VESA Adaptive Sync Smart PlatformwebOS · Wi-Fi built-in · AirPlay 2 · LG Channels · Netflix, Disney+, Prime Video, cloud gaming · LG ThinQ RemoteLG Magic Remote — included Speakers2× 10W stereo speakers — built-in (20W total) HDMI 2.1 ×22× HDMI 2.1 — supports console gaming at 4K@120Hz or WQHD@240Hz · eARC DisplayPort 1.41× DisplayPort 1.4 — WQHD@240Hz · primary PC gaming connection USB-C1× USB-C — DisplayPort Alt Mode · 65W Power Delivery (charges laptops) · upstream data LAN1× RJ-45 — built-in Ethernet for webOS streaming and wired PC connection via hub USB-A ×22× USB 2.0 Type-A — downstream hub ports Audio Out1× 3.5mm headphone / line out Stand ErgonomicsTilt -10° to +15° · Swivel ±10° · Height ±120mm · Pivot (portrait mode) · VESA 100×100mm Dimensions (w/ stand)993mm W × 457mm D × 218mm min H (39.1" × 18.0" × 8.6") Weight13.5 kg (29.8 lbs) with stand PowerInternal PSU · 100–240V AC 📦Package Contents — All Original Accessories Everything in the Box — 45GX90SA-B ✅LG UltraGear 45GX90SA-B MonitorBlack · 45" OLED WQHD · 240Hz ✅Ergonomic Stand + BaseTilt · Swivel · Height · Pivot ✅LG Magic RemoteFor webOS navigation ✅Power SupplyOriginal LG power adapter ✅CablesHDMI + DisplayPort + USB-C included ✅Quick Start GuideOriginal documentation ⚠️Buyer Notes 🆕 Open Box · New · All Accessories: Stand · Remote · PSU · Cables · Guide Open box, new condition. Every original accessory is included: ergonomic stand and base, LG Magic Remote, power supply, HDMI cable, DisplayPort cable, USB-C cable, and quick start guide. 🖥 GPU Requirements for WQHD@240Hz · DP 1.4 or HDMI 2.1 Required To run 3440×1440 at 240Hz, your GPU needs DisplayPort 1.4 or HDMI 2.1. DisplayPort 1.4 (using the included DP cable) is the primary PC gaming connection. HDMI 2.1 supports full 240Hz at WQHD from compatible GPUs (NVIDIA RTX 30 series and newer, AMD RX 6000 series and newer) and PlayStation 5 / Xbox Series X at their supported resolutions and refresh rates. G-Sync Compatible and FreeSync Premium Pro both work via HDMI 2.1 and DisplayPort 1.4. 🔌 USB-C Charges Your Laptop While Connecting It · 65W Power Delivery · Single Cable Setup The USB-C port supports 65W Power Delivery alongside DisplayPort Alt Mode — one USB-C cable from your laptop handles both display output and charging simultaneously. Compatible with MacBook Air, most thin-and-light Windows laptops, and any device using USB-C power delivery. Laptops requiring more than 65W (gaming laptops, MacBook Pro 16") may charge slowly or supplement with their own charger. The USB-C connection also activates the built-in USB hub, making the two USB-A ports and LAN available to your laptop through the monitor. 📺 webOS Smart Monitor · Magic Remote · Wi-Fi · No PC Required for Streaming The 45GX90SA-B runs LG's webOS smart platform — the same system used in LG's premium TVs — independently of any connected PC or console. With the included Magic Remote, you can navigate Netflix, Disney+, Prime Video, LG Channels, and compatible cloud gaming services (GeForce Now, Xbox Cloud Gaming) directly on the monitor over Wi-Fi, without any additional device. AirPlay 2 lets Apple devices mirror wirelessly. webOS also enables LG's ThinQ AI-driven picture and audio optimization, which adjusts settings based on content type in real time. 🔊 20W Built-In Stereo Speakers · Anti-Glare Matte Panel · 800R Curvature Three practical advantages over competing ultra-wide OLEDs: the 20W stereo speakers are built into the panel frame and produce usable audio without a separate sound system — functional for casual gaming, streaming, and video calls. The anti-glare matte coating reduces ambient reflections in mixed-lighting environments without introducing the haze of some anti-reflection treatments — preferable for desk setups near windows. The 800R curvature is steep enough that the screen edges wrap visibly into peripheral vision at typical viewing distances of 60–80cm, significantly increasing the sense of immersion compared to 1800R panels. 🛡 OLED Pixel Cleaning · Normal Use Poses No Burn-In Risk · Desk Depth Requirement LG's built-in Pixel Cleaning cycle runs automatically during standby to maintain panel health — gaming and varied content use carries no meaningful burn-in risk. Desk requirements: the monitor is 39.1" wide and 18" deep with the stand, weighing 29.8 lbs — confirm your desk can accommodate this before purchasing. A monitor arm (VESA 100×100mm) reduces the depth footprint to the panel itself. The 800R curvature means you'll want a viewing distance of 60–80cm for the full immersive effect. 📋Seller Terms 🚚 ShippingFree expedited shipping. Fully insured.
