DAHUA LM34-E330CA is a 34" (86.4 cm) UltraWide Quad HD monitor with a 3440×1440 VA LCD panel and a 21:9 curved screen. The 1500R curvature and 300 cd/m² brightness deliver immersive wide-format viewing suitable for multitasking, multimedia and gaming. The monitor includes height adjustment and VESA mounting support, and offers a 1 ms response time with a typical 3500:1 contrast ratio.

Advantages

The curved VA panel provides deeper contrast and a wide color gamut (120% sRGB; typical coverage values for NTSC, DCI-P3 and Adobe RGB are listed at 85%), producing clear, vivid images. With a 200 Hz refresh rate, 1 ms response time and adaptive sync support, the display reduces motion blur, tearing and lag. Flicker-free technology and an energy consumption of around 47 W contribute to comfortable and efficient long-term use.

Suitable for

• Productivity and multitasking with ultra‑wide 21:9 workspace
• Multimedia editing and content review requiring wide color gamut and high contrast

Enable adaptive sync in your GPU or monitor settings if supported to reduce tearing. Use the on-screen display to fine‑tune brightness, color mode and response settings for your tasks.

Recommendations

For long sessions, set brightness and color temperature to comfortable levels and enable flicker‑free mode. Use a GPU and cable that support 3440×1440 at high refresh rates to fully utilise the monitor's 200 Hz capability.
