Overview

LM340UW6-SSA3 LG Display 34 inch  3440(RGB)×1440  tft display 

The LM340UW6-SSA3 features an UltraWide QHD resolution (3440 × 1440) with a 21:9 aspect ratio, providing significantly more screen real estate than standard widescreen displays. It utilizes LG’s renowned IPS (In-Plane Switching) technology, ensuring wide viewing angles of 89/89/89/89 and consistent color reproduction. The panel uses a high-speed 4-lane eDP (Embedded DisplayPort) interface to handle its massive data throughput, supporting 1.07 billion colors (10-bit) for incredibly smooth gradients. With a brightness of 400 cd/m² and a contrast ratio of 1000:1, it is equipped with a high-performance WLED backlight system and an Anti-glare (3H) hard coating to minimize reflections.

FAQ:

What is the aspect ratio of this 34-inch screen? What are its advantages over a standard 27-inch screen?

This panel features a 21:9 ultra-wide aspect ratio. Compared to a 16:9 27-inch screen, it provides a broader field of view, making it ideal for multi-tasking, video editing, and immersive gaming.

34-inch screens are very large and fragile. How do you pack them to ensure safety during international transit?

We use original factory wooden frames or heavy-duty foam trays for securing the panel, with multi-layered corrugated boxes on the outside. For individual units, we provide customized wooden crates to withstand severe vibrations during international logistics.

Can you guarantee this is a brand-new Grade A panel produced by LG Display?

We promise to supply original brand-new LG Display products. Every panel is strictly inspected before shipping to ensure no bright spots, no light leakage, and no scratches, fully meeting Grade A industrial standards.
