LG 45GR75DC-B 45-inch UltraGear™ QHD 1440P 1ms 200Hz Curved Gaming Monitor with USB Type-C™

LG 45GR75DC-B 45-inch UltraGear™ QHD 1440P 1ms 200Hz Curved Gaming Monitor with USB Type-C™

The LG 45GR75DC-B UltraGear gaming monitor redefines immersive gaming and productivity with its colossal 45-inch ultra-wide curved display. Featuring Dual QHD (5120×1440) resolution at 32:9 aspect ratio, 1500R curvature, 200Hz refresh rate, and DisplayHDR 600 with 95% DCI-P3 color coverage, it wraps you in a panoramic visual experience that transforms gaming, multitasking, and content creation.

Panoramic 32:9 Ultra-Wide Display

At 5120×1440 resolution, the 45GR75DC delivers the equivalent of two side-by-side 27-inch QHD monitors seamlessly fused into one massive canvas. The 32:9 aspect ratio provides 78% more horizontal screen space than standard 16:9 displays, enabling ultra-wide field of view in racing and flight simulators, expansive battlefields in FPS games, and real-time multi-window productivity workflows without bezels interrupting your view.

1500R Immersive Curvature

The aggressive 1500R curvature (1500mm radius) wraps around your field of vision, creating a natural, enveloping experience that reduces eye movement and enhances peripheral awareness. This tight curve is specifically engineered for ultra-wide displays, ensuring consistent viewing distance across the entire 45-inch span and pulling you deeper into game worlds and content.

200Hz + 1ms Response: Speed Meets Smoothness

At 200Hz, the monitor refreshes 200 times per second — 3.3x faster than standard displays. Combined with 1ms (GtG) response time, it eliminates motion blur, ghosting, and stuttering, delivering buttery-smooth gameplay even in the fastest-paced action. Whether tracking opponents in competitive shooters or navigating tight corners in racing sims, responsiveness is instantaneous.

AMD FreeSync Premium Pro: Tear-Free HDR Gaming

FreeSync Premium Pro synchronizes refresh rates with AMD GPUs, eliminating screen tearing and stuttering while maintaining low latency. Unlike basic FreeSync, Premium Pro includes HDR tone mapping and Low Framerate Compensation (LFC), ensuring smooth performance even when frame rates fluctuate. The result: fluid, tear-free gaming with enhanced HDR visuals.

DisplayHDR 600 + DCI-P3 95%: Cinematic Visuals

VESA DisplayHDR 600 certification guarantees peak brightness of 600 cd/m² (in HDR mode) with local dimming for deeper blacks and brighter highlights. DCI-P3 95% color gamut coverage delivers cinema-grade color accuracy with 1.07 billion colors (10-bit), producing lifelike skin tones, vibrant game worlds, and accurate content creation workflows. HDR10 support enhances dynamic range in supported games and media.

USB-C with 90W Power Delivery: Single-Cable Convenience

Connect, charge, and transmit data with a single USB-C cable. The 90W Power Delivery charges compatible laptops (MacBook Pro, Dell XPS, ThinkPad) while simultaneously displaying video and enabling USB hub functionality. Perfect for hybrid work/gaming setups where laptop docking simplicity is essential.

Built-In KVM Switch: Seamless Multi-PC Control

Control two PCs with a single keyboard and mouse using the integrated KVM (Keyboard, Video, Mouse) switch. Ideal for streamers managing gaming PC + streaming PC, IT professionals switching between work/personal systems, or content creators juggling multiple workflows — all without cable swapping.

Picture-in-Picture & Picture-by-Picture

Display content from two input sources simultaneously. PiP (Picture-in-Picture) overlays a secondary window over the main display, while PbP (Picture-by-Picture) splits the screen to show both sources side-by-side. Monitor Discord chat while gaming, reference documents while coding, or compare content from two systems.

Enhanced Gaming Intelligence

• FPS Counter: Real-time frame rate display
• Crosshair Overlay: Center-screen crosshairs for enhanced aiming precision
• Black Stabilizer: Brightens dark scenes without overexposing bright areas, revealing hidden enemies
• Dynamic Action Sync: Minimizes input lag for instantaneous response
• Game Mode Presets: Optimized settings for Gamer, FPS, RTS, and more

DTS Headphone:X: 3D Spatial Audio

Immersive 3D audio positioning through the 4-pole headphone jack (audio + mic) delivers accurate spatialization and localization, helping you pinpoint enemy footsteps, gunfire direction, and environmental cues in competitive gaming.

Live Color Low Blue Light

Reduces harmful blue light emissions while maintaining accurate color reproduction through combined RGB hardware and software adjustments. Game comfortably for extended sessions without sacrificing visual quality.

Full Ergonomic Adjustability

110mm height adjustment, tilt (-5° to +15°), and swivel (±15°) enable precise positioning for optimal viewing angles. VESA 100x100mm mounting supports aftermarket arms or wall mounts. The 3-sided virtually borderless design maximizes screen real estate and creates a clean, modern aesthetic.

A panoramic ultra-wide gaming monitor that combines immersive curvature, HDR600 visual excellence, and professional connectivity for the ultimate gaming and productivity experience.

Important Notes:

• GPU Requirements: Driving 5120×1440 @ 200Hz requires a high-end GPU (RTX 4070/4080, RX 7800 XT or better recommended)
• DisplayPort or HDMI 2.1 Required: Full 200Hz at DQHD requires DisplayPort 1.4 or HDMI 2.1; older HDMI versions limited to lower refresh rates
• USB-C Limitations: 90W Power Delivery may be insufficient for high-performance gaming laptops under full load (some gaming laptops require 100W–240W)
• Desk Space: 45-inch ultra-wide requires ~1.1m (42.7″) horizontal desk space; verify desk dimensions
• Viewing Distance: Optimal viewing distance: 75–100cm (30–40 inches) for immersive experience without excessive head movement
• VA Panel Characteristics: Excellent contrast and color but narrower viewing angles than IPS; may exhibit slight color shift at extreme angles on ultra-wide displays
• KVM Switch: Requires connected USB devices; may not support all peripheral types (verify compatibility with wireless receivers, USB hubs)
• HDR Content: HDR600 performance depends on content support (games, movies); not all content supports HDR
• Aspect Ratio Compatibility: 32:9 ultra-wide may display black bars in content optimized for 16:9; some games may require configuration for proper ultra-wide support

Ideal Use Cases:

• Racing and flight simulators (immersive FOV)
• Competitive FPS gaming (peripheral awareness)
• Content creation (video editing timeline, music production DAW)
• Multi-window productivity (code + documentation + preview)
• Streaming (game + OBS + chat simultaneously)
• Stock trading and data analysis (multiple charts side-by-side)
