LG 28MQ780‑B DualUp Review: Honest Overview

  • Niche ergonomic design with solid build quality
  • 60Hz refresh rate and warranty caveats

Positive Feedback & Highlights

  • Seamless multi‑PC switching via KVM

Many users report a seamless workflow when toggling between laptops, praising the PBP and auto-switching USB‑C functionality. The tall display delivers enough room for code, documents, and chats without constant scrolling.

Negative Reviews & Rumor Investigation

  • Persistent screen flickering and backlight issues
  • Limited official support and flat‑rate repairs

Several buyers experienced intermittent flicker after months of use, plus poor customer service that demanded paid repairs. No major safety rumors, but reliability concerns are well‑documented in user reports.

Who Should Consider LG DualUp?

  • Developers, editors, and multitaskers craving vertical space
  • Users with in‑house tech support or extended warranty

If you value tall workspaces and have backup support for warranty needs, DualUp can streamline productivity. Casual gamers or those needing high refresh rates should look elsewhere.
